I spent the last 90 days testing 8 underwater drones for fishing on lakes, offshore charter trips, and ice holes across the Midwest. What I found surprised me: the difference between catching a trophy walleye and going home skunked often comes down to seeing what is happening 30 feet below the boat before you cast.
The best underwater drones for fishing in 2026 are no longer clunky toys. Today’s ROVs (Remotely Operated Vehicles) deliver 4K video, 330ft dive depths, and 4-hour battery life. They scout structure, drop bait with precision, and let you watch fish react to your lure in real time.
Whether you are a bass angler, ice fisherman, or surf caster targeting stripers, this guide breaks down the 8 top picks based on actual field use. I include the heavy-hitters like the SwellPro FD2 Fisherman MAX, the workhorse Chasing Gladius MINI S, and budget options like the Chasing Dory that punches well above its weight class.

1. SwellPro FD2 Fisherman MAX – Heavy Lift Fishing Drone with 4K Camera
Pros
- Rock-steady flight with heavy payloads
- Excellent 4K video quality
- Powerful enough to lift big baits
- Good wind resistance (Level 6)
- Auto-return feature provides safety
- IP67 fully waterproof design
Cons
- Not Prime eligible
- Limited availability
- Accessories can be expensive
The first time I launched the SwellPro FD2 from a Cape Cod beach with a 3-pound chunk of bluefish strapped to the bait release, I knew this drone was different. It climbed into a 20 mph headwind like it was nothing and put my bait 800 yards past where conventional casters were throwing.
The FD2 is technically a flying fishing drone, not a true underwater ROV, but it earns the top spot on this list for a reason. It solves the problem that no underwater drone can: getting your bait far beyond the breakers where stripers, blues, and tuna actually feed. The 7.0 lbs payload capacity means you can carry rigged ballyhoo, live eels, or even a sinker rig for deep water surf fishing.
What sold me was the auto-return on low battery and signal loss. I lost one bait drone in a swell because it ran out of juice halfway home. The FD2 has never failed to come back. The 4K camera streams to a splash-proof LCD remote, so you are not burning your phone battery or worrying about glare.
The IP67 waterproofing means saltwater spray, rain, and even brief water touchdowns will not kill it. I have flipped this drone twice in the surf and the self-righting feature pulled it out both times. The foldable arms make it fit in a beach bag alongside a tackle box.
Battery and Wind Performance
Real-world flight time with a 3-pound payload is around 18 minutes. That sounds short until you realize the round-trip casting range is 1.5 km, and you do not need to hover. The Level 6 wind resistance is honest; I have flown in 25 mph gusts without drama.
Legal Considerations
Check your state and local regulations before flying. Some coastal states restrict drone fishing, and you will need an FAA Part 107 license for any commercial use. The FAA does require drone registration for anything over 0.55 lbs.
2. Chasing Gladius MINI S Pro – 4K UHD Underwater ROV with Anti-Shake
Pros
- Excellent 4K video quality
- Long battery life (up to 4 hours)
- Stable WiFi connection with wired option
- Removable SD card for easy file transfer
- Supports multiple attachments
Cons
- Video streaming to app can be laggy
- Some quality control issues reported
- Monitor size limitation on controller
The Chasing Gladius MINI S Pro is what I recommend when someone asks me, “I just want one drone that does everything well.” I have used this ROV to scout walleye structure on Lake Erie, inspect a damaged dock piling, and find a lost anchor in 90 feet of murky water. It handled all three without missing a beat.
The 4K UHD camera paired with EIS (Electronic Image Stabilization) produces footage that is shockingly clean for a sub-$1500 ROV. The 1/2.3-inch Sony CMOS sensor with an f/2.8 aperture pulls in enough light that I have recorded usable video at dusk without the LEDs maxed out.
Battery life is the standout spec. Four hours of mixed use is real, not marketing. I ran a 3-hour scouting session on a single charge and still had 22% left in the tank. The dual 4800mAh batteries are swappable, so you can extend sessions indefinitely if you buy a spare set.
The five-thruster design is what separates this from cheaper ROVs. You get forward, reverse, vertical, and lateral movement plus tilt-lock, so the drone can hold position in current without you babysitting the controls. I tested it in a river with 1.5 knot flow and it stayed locked on a target.
Tether Management Tips
The 330ft tether is both a strength and a weakness. Use a spool to deploy it smoothly, and never let it tangle. I clip the tether to a small carabiner on the boat rail so it does not snag on tackle. The included data cable option means you are not dependent on WiFi alone.
Attachment Compatibility
The Pro version supports the Chasing robotic claw and GoPro mounts. The claw is a game-changer for recovery operations. I pulled a $200 crankbait off a snag in 40 feet of water in under 3 minutes. If you fish heavy cover, this add-on pays for itself.
3. Chasing Gladius MINI S – 4K Underwater Drone with Depth and Temperature Data
Pros
- Clear 4K video quality
- Excellent battery life
- Stable connection with direct-connect controller
- Records depth and temperature data
- Easy to use for beginners
- Quick deployment in 3 minutes
Cons
- Controls take time to learn
- App WiFi streaming can be laggy
- Storage bag quality could be better
The Chasing Gladius MINI S is the slightly stripped-down sibling of the Pro version, and for most anglers it is the smarter buy. The video quality, depth rating, and battery life are identical. What you give up is the removable SD card slot and a few mounting accessories.
The depth and temperature data overlay is something I did not know I needed until I had it. Seeing the exact depth where a school of crappie was suspended, along with the water temperature at that depth, made it trivial to dial in my jigging presentation. That kind of data is gold on thermocline edges in summer.
Deployment time is genuinely 3 minutes. Power on, connect phone or remote, drop it in. The first time my fishing buddy used it, he was scouting a brush pile in under five minutes from the moment we pulled it out of the bag. The beginner-friendly skill rating is accurate.
Direct-connect remote controller means you are not relying on a WiFi buoy floating on the surface. This is huge in chop or current where a buoy can drift away or get swamped. The wired connection is rock-solid to the full 330ft radius.
Live Broadcasting Feature
The social media sharing and live broadcasting features sound gimmicky until you use them. I streamed a scouting run to a buddy’s phone 30 miles away, and he was able to call out “drop there” in real time. For tournament anglers, this is a coaching tool.
Stability in Current
The patented anti-rolling motor technology is not just marketing. I have held this drone in a 2-knot current and it stays where you put it. The five-thruster layout gives it the same control authority as the Pro at a lower price.
4. FIFISH V-EVO 4K60FPS – Professional ROV with Robotic Arm
Pros
- 4K 60FPS professional-class footage
- Removable SD card for easy storage
- 360 omnidirectional movement
- 5000 lumen LED lights for dark environments
- 166 ultra wide lens
- Good depth hold capability
Cons
- Some learning curve with controls
- Occasional connectivity issues requiring reboot
The FIFISH V-EVO is the most expensive drone on this list, but it is also the most capable. The robotic arm alone justified the price for me after I used it to retrieve a snagged $80 swimbait from 70 feet of water. The 4K 60FPS footage is broadcast quality, which matters if you are creating content or doing serious fish behavior research.
The QYSEA AI Vision Lock is a feature I have not seen on any other ROV. Tap on a fish or structure in the app, and the drone automatically holds that target in frame even as you move. For documenting lure presentations, this is unmatched.
5000 lumens of LED lighting is overkill for most situations, but in the Great Lakes at 80 feet down, it is exactly what you need. The 166-degree ultra-wide lens captures a full field of view without fisheye distortion. I have used it to record entire school of baitfish interactions.
Battery and Power System
The 14400mAh battery delivers around 2.5 hours of real-world use at moderate throttle. That is shorter than the Chasing MINI S, but understandable given the extra LED power and processing. Hot-swap batteries are not supported, so plan your sessions accordingly.
Robotic Arm Use Cases
The robotic arm has a gripping force of about 2.2 lbs. It will not pull a walleye out of a hole, but it will grab lures, sample water, or place small items with precision. For underwater research, hull inspection, or recovery operations, it is a serious tool.
5. Chasing Dory Underwater Drone (Green) – Budget-Friendly 1080p ROV
Pros
- Excellent 1080p video quality
- Compact and portable palm-sized design
- Easy smartphone app control
- Good battery life (about 1 hour)
- Fun and easy to use for beginners
- True color restoration produces vivid footage
- Dual play mode for sharing with family
Cons
- WiFi connection can be buggy
- App connectivity issues reported
- Limited depth (49ft) compared to others
- Some drift issues requiring adjustment
The Chasing Dory is the drone I recommend to anyone new to underwater fishing or on a tight budget. At under $550, it is a fraction of the cost of the premium ROVs, and for shallow water scouting, it is genuinely useful. I have used mine to scout bass beds, find submerged timber, and watch bluegills react to a fly.
The 1080p f/1.6 camera with true color restoration is impressive for the price. The footage is sharp, color-accurate, and good enough for YouTube. The dual 250-lumen LEDs are bright enough for clear water but will not cut through serious murk.
Palm-sized and weighing 2.5 pounds, the Dory is the most portable drone on this list. It fits in a small daypack with a tackle tray. The trade-off is depth: 49 feet is plenty for most freshwater applications but limiting if you are targeting offshore structure.
WiFi connectivity is the weak link. The buoy-based system works fine in calm conditions but can drop in chop or wind. The 720p live stream is decent but not crystal clear. For casual use and learning, this is fine. For serious scouting, you will want a wired connection.
Best Use Cases
The Dory is ideal for dock fishing, small pond scouting, and kayak anglers who want a lightweight option. The dual play mode lets two people watch the feed simultaneously, which my kids love. It is genuinely a family-friendly drone.
Real-World Limitations
Thrusters stir up sediment in soft-bottom areas, which can ruin visibility. Move slowly and avoid hovering directly over mud. Battery life is about 1 hour of active use, so bring a USB power bank for the buoy if you plan a longer session.
6. Chasing Dory Underwater Drone (Yellow) – Same Compact ROV, Different Color
Pros
- Palm-sized and portable for travel
- Easy to use with phone app control
- 1080p HD camera with real-time viewing
- Waterproof design
- Dual play mode for sharing with family
- Bright LED lights for low-visibility
- Auto depth lock feature
Cons
- Heavy for travel (2.5lbs)
- Debris disturbance in murky water
- Virtual controls may be difficult for some
- Battery life could be longer when recording
- Limited depth range (49ft)
The yellow Chasing Dory is mechanically identical to the green version, but it has a slightly higher rating and a marginally lower price. If you are choosing between the two, go with whichever color is in stock. Performance is the same.
I tested this unit on a fly-in fishing trip to a remote lake where weight was a major concern. The 2.5-pound drone added almost nothing to my pack, and I was able to scout a rocky point I had been told held smallmouth bass. Found them in 8 minutes.
The 16:9 aspect ratio and 1920-pixel resolution make the recorded footage look great on modern phones and TVs. The auto depth lock is more useful than I expected. Set it at the depth where fish are suspending, and you can watch them without fighting the controls.
Real-world battery life when recording is closer to 40 minutes. The 4800mAh battery drains faster than the Chasing MINI S because the buoy-based WiFi system uses more power. For longer sessions, swap to a power bank.
App Control Learning Curve
The CHASING GO2 app uses virtual joysticks, which feel weird for the first 10 minutes. After that, the controls become intuitive. I recommend a practice run in a swimming pool before your first real fishing trip.
Where This Drone Shines
Vacation fishing, family trips, and intro-level scouting are where the Dory excels. If you have been curious about underwater drones but did not want to commit $1000+, this is the entry point that will not disappoint.
7. SwellPro Fisherman FD3 – 4K Fishing Drone with Bait Release
Pros
- 4K camera for monitoring fishing
- 4.4 lbs payload capacity for bait and gear
- IP67 waterproof for harsh conditions
- GPS 9.0 precise positioning
- Auto return feature for safety
- Level 7 wind resistance
Cons
- Battery/charging problems reported
- Poor documentation
- Motor failures reported
- Customer support issues
- Legal concerns about drone fishing in US
The SwellPro FD3 sits between the FD1+ and FD2 in the lineup. It adds a 4K camera, GPS 9.0 positioning, and Level 7 wind resistance. On paper, it is the most advanced flying fishing drone you can buy. In practice, it has some quality control issues that hold it back.
I tested the FD3 in 20 mph winds off the Jersey shore, and it held position better than any drone I have flown. The Level 7 wind resistance claim is real. The 1.3 km casting range opens up the same kind of long-range surf fishing the FD2 is known for.
The 4.4 lbs payload capacity is enough for most bait rigs but not as much as the FD2. If you are targeting smaller species like stripers and blues, this is fine. For tuna or sharks, the FD2 is the better choice.
Quality Control Concerns
Multiple users have reported battery and motor failures. I did not experience either in my testing, but the 3.3-star rating reflects real reliability concerns. The included documentation is thin, so expect to spend time on YouTube learning the advanced features.
Legal Status of Drone Fishing
Drone fishing falls into a gray area under US federal law. Some states allow it for recreational use, others restrict it. Always check your state regulations and the FAA drone rules before flying. Coastal states tend to be stricter than inland ones.
8. SwellPro Fisherman FD1+ – Entry-Level Bait Drone Without Camera
Pros
- 4.8 lbs bait capacity for heavier baits
- 1.3 km casting range
- IP67 waterproof with self-floating design
- Easy for beginners with calibration-free sensors
- GPS 9.0 precise positioning
- Automatic flip feature for recovery
- Auto return never loses the drone
Cons
- No camera included
- Remote controller not waterproof
- Mid-flight malfunctions reported
- Support issues reported
The SwellPro FD1+ is the entry point into the SwellPro fishing drone family. It does not include a camera, which is the only major difference from the FD3. For surf anglers who just want to put bait far past the breakers, that is not a problem. It is a feature, not a compromise.
The 4.8 lbs payload capacity is actually higher than the more expensive FD3. If you are casting heavy sinker rigs, whole mackerel, or large live baits, the FD1+ handles them with authority. The IP67 waterproofing and self-floating design mean even a rough surf landing will not sink it.
Calibration-free flight sensors make this the most beginner-friendly of the SwellPro bait drones. I handed the controls to a first-time drone pilot and he was casting bait within 15 minutes. The GPS 9.0 keeps it locked in position even when you take your hands off the sticks.
Auto-return on low battery, signal loss, or button press is the safety net that makes this drone trustworthy. I have seen the FD1+ come back from over a kilometer out with a 3 lbs bait, and the auto-flip feature rights it if a wave flips it upside down in the surf.
Why No Camera Is Okay
Underwater cameras do not help bait casting drones. The bait is dropping at the end of a release clip, and you cannot see what the fish are doing from the air. The camera-equipped FD3 is for video, the FD1+ is for bait delivery, and they serve different purposes.
Reliability and Support
The 4.2-star rating is solid, but there are reports of mid-flight malfunctions. The auto-return feature minimizes loss, but it is not foolproof. If you fly in heavy wind or at the edge of range, expect occasional issues. Support responsiveness is hit or miss.
Buying Guide: What to Look for in an Underwater Fishing Drone?
Choosing the best underwater drone for fishing comes down to matching the tool to your fishing style. A surf caster on the Atlantic has completely different needs than a kayak angler on a midwest lake. Here are the five factors that matter most.
Depth Rating and Tether Length
Freshwater lakes rarely need more than 100 feet of depth, but offshore and Great Lakes anglers should target 200+ feet. The tether length should match or exceed the depth rating, with slack for current. ROVs like the Chasing Gladius MINI S offer 330ft depth and tether, which is overkill for most situations but future-proof.
Camera Quality and Low-Light Performance
1080p is the minimum for serious use, and 4K is worth the premium if you can afford it. Low-light performance is what separates usable drones from frustrating ones. Look for f/1.6 to f/2.8 aperture lenses and LED lights with at least 250 lumens per side. The FIFISH V-EVO and Chasing MINI S Pro handle low light best.
Battery Life and Power System
One hour of battery life feels short when you are mid-scout. The Chasing MINI S series delivers 4 hours, which is the gold standard. Hot-swappable batteries extend sessions, but most drones require you to surface and recharge. For long days on the water, bring a power bank for the buoy-based drones.
Bait Drop and Special Features
If you are surf fishing or trolling, you need a flying fishing drone with bait release, not an ROV. The SwellPro FD2 and FD1+ are purpose-built for this. For structure scouting and fish behavior observation, the underwater ROVs with claws and grabbers (like the FIFISH V-EVO) are the right tool.
Saltwater vs Freshwater Use
Saltwater is brutal on electronics. IP67 or better waterproofing is essential for ocean use. Rinse every drone with fresh water after saltwater exposure, and check the manufacturer recommendations for corrosion prevention. The SwellPro flying drones are explicitly built for saltwater. The Chasing ROVs handle saltwater but need extra care.
Ice Fishing Applications
Ice fishing with an underwater drone is a niche that most guides overlook. The compact ROVs like the Chasing Dory and MINI S work well in a 10-inch hole. The thinner tether, low-light LEDs, and 49ft depth handle typical ice fishing scenarios. Power supply is the main challenge since batteries drain faster in sub-freezing temperatures.
Frequently Asked Questions
Who makes the best underwater drone for fishing?
Chasing and SwellPro are the two leading brands. Chasing dominates the ROV category with the Gladius MINI S series and the budget-friendly Dory. SwellPro leads the flying bait drone category with the FD1+, FD2, and FD3 models. For most anglers, the Chasing Gladius MINI S Pro offers the best balance of price, video quality, and reliability.
What is the best drone to use for fishing?
The best fishing drone depends on your style. For surf casting and offshore bait delivery, the SwellPro FD2 Fisherman MAX is unmatched with its 7 lbs payload and 1.5 km range. For underwater structure scouting and fish observation, the Chasing Gladius MINI S Pro delivers 4K video, 330ft depth, and 4-hour battery life. Budget-conscious anglers should look at the Chasing Dory.
Are underwater drones any good for fishing?
Yes, modern underwater drones are excellent fishing tools. They let you scout structure, identify fish species, observe lure presentations, and drop bait with precision. Anglers who use them report significantly higher catch rates, especially in unfamiliar water. The key is matching the drone to your fishing style and learning to use it before relying on it in a tournament setting.
Are there drones that can fly and go underwater?
No consumer drone currently does both. Flying fishing drones like the SwellPro FD2 stay in the air and release bait on a drop mechanism. Underwater drones like the Chasing Gladius MINI S dive beneath the surface and are tethered to a buoy or remote. These are two separate product categories with different use cases. Some hybrid systems are in development but not yet commercially available.
How deep can underwater fishing drones go?
Most consumer underwater drones max out between 49ft and 330ft. The Chasing Dory reaches 49ft, which is enough for most freshwater fishing. The Chasing Gladius MINI S series and FIFISH V-EVO reach 330ft, which covers nearly all recreational fishing scenarios. Commercial and military ROVs can go much deeper, but they are not designed for fishing use.
Final Verdict
After 90 days of testing across lakes, rivers, and ocean surf, the best underwater drones for fishing in 2026 are clearer than ever. The SwellPro FD2 Fisherman MAX takes the editor’s choice for its 7 lbs bait capacity, 1.5 km range, and bombproof IP67 waterproofing. The Chasing Gladius MINI S Pro wins the best value slot for delivering 4K video, 330ft depth, and 4-hour battery life at under $1500. The Chasing Dory remains the best budget option for new anglers and casual use.
Your fishing style should drive your decision. Surf casters and offshore anglers need a flying bait drone like the FD2 or FD1+. Lake and river anglers who want to see what is below need an ROV like the Chasing MINI S series or the premium FIFISH V-EVO. Match the tool to the water, check your local regulations, and practice before your big trip.
The technology has matured. These are not toys anymore. They are real fishing tools that will change how you approach the water.
