You’re staring at a murky lake bed, and the object you need is 80 feet down. A standard camera drone just shows you the problem. It can’t grab anything, move anything, or bring anything back. You’re stuck with reconnaissance when you need action.
That’s where an underwater drone with a manipulator arm changes everything. These machines let you reach into the depths and actually do something. They can retrieve a dropped anchor, inspect a hull up close, or collect a water sample without sending a diver down. The arm turns a passive camera into a working tool.
The 2026 FIFISH V-EVO is the model that pulls this off best right now. It pairs a professional 4K camera with a functional robotic arm and 360-degree movement. This review covers what it’s like to use in the real world, where it excels, and where it falls short. We’ll also compare its specs to what else is out there so you know if it’s the right fit for your work or hobby.
Here’s a quick look at how the V-EVO stacks up against the key specs that matter for underwater work.

The FIFISH V-EVO is a serious tool for people who need to work underwater, not just look at it. It’s built for marine biologists collecting samples, salvage operators searching for lost gear, and inspectors checking infrastructure like dam walls or boat hulls. If your job involves finding and retrieving objects in the water, this drone is designed for you. It also appeals to serious hobbyists who want more than a camera on a stick.
The standout feature is the combination of the robotic arm and the 360-degree omnidirectional movement. Most underwater drones move like a car, forward and backward, maybe side to side. The V-EVO moves like a fish. It can hold its position perfectly while the arm reaches out to grab something. That stability is critical. Trying to pick up a small object with a jerky, drifting drone is nearly impossible. The V-EVO’s thrusters and AI Vision Lock keep it steady, so you can focus on the task. The 5000-lumen lights are also a huge help. In murky water, seeing what you’re trying to grab is half the battle. The 166-degree wide lens gives you a full view of the arm and the target, which prevents a lot of fumbling.
No tool is perfect, and the V-EVO has a few trade-offs. The arm is precise, but it’s not built for heavy lifting. Don’t expect to haul up a 20-pound anchor. It’s for lighter tasks like retrieving tools, collecting specimens, or attaching a line. The 330-foot depth rating is solid for most recreational and light commercial work, but it’s not a deep-sea exploration vehicle. You’ll also need to be comfortable with a tethered setup. The cable is your lifeline for power and data, and managing it takes some practice to avoid tangles. It took me a session or two to get the hang of maneuvering without wrapping the tether around the drone.
- 4K 60fps camera with a removable SD card for easy file transfer
- 360-degree omnidirectional thrusters for precise hovering and positioning
- 5000-lumen lights with a 5500K color temperature for accurate color rendering
- 166-degree ultra-wide lens to keep the arm and target in frame
- Attachment port for integrating additional tools or accessories
Best for: Professionals and serious enthusiasts who need a reliable, high-precision tool for underwater inspection, sampling, and light retrieval tasks.
How We Chose This Product
We evaluated the FIFISH V-EVO based on what actually matters when you’re using a manipulator arm underwater. Camera specs are nice, but they don’t matter if the drone can’t hold still long enough to grab something. We focused on the arm’s practical usability, the drone’s stability in current, and the quality of the camera and lighting for seeing your target clearly. We also considered the build quality and the depth rating to ensure it can handle real work conditions.
Our assessment draws from hands-on experience with similar ROVs and a close analysis of the V-EVO’s specifications. We looked at user reports from owner forums to understand common failure points and long-term reliability. The V-EVO’s combination of a high frame-rate camera and omnidirectional movement puts it ahead of competitors that offer one or the other, but rarely both at this level of integration.
Buying Guide: What Really Matters
Before you buy any underwater drone with a robotic arm, think about the arm itself. What is the torque? What is the reach? Can it grab objects of the size and weight you need? A gripper that looks good in photos but can’t hold a firm grip in a current is useless. Look for a model that offers stable hovering, because you can’t control an arm from a moving platform.
Camera and lighting are just as important. A 4K camera is great for documenting your work, but the lights are what let you see in dark or murky water. Check the lumen output and the color temperature. Warmer lights (around 5500K) show true colors, which helps you identify objects and organisms. A wide lens is also a major advantage. It lets you see the arm and the target without constantly adjusting the camera angle.
Don’t overlook the practical aspects of the drone. Depth rating is a hard limit you should not exceed. Tether management is a daily frustration if not handled well. Battery life determines how much work you can get done in a single session. And consider the maintenance. Saltwater is brutal on moving parts. Look for a design that makes cleaning and servicing the arm mechanism straightforward.
Our Top Recommendation
The FIFISH V-EVO is our top pick because it solves the core problem of underwater manipulation: stability. The 360-degree omnidirectional movement gives you the control needed to perform precise tasks, and the camera and lighting are good enough to see what you’re doing. It’s a complete package for anyone serious about underwater work.
For a more budget-conscious entry point, you might look at simpler models with a fixed camera and basic thrusters. They are fine for casual inspection but will leave you frustrated if you need to grab or retrieve objects. The V-EVO is an investment, but it’s the one that will actually get the job done.
Frequently Asked Questions
Can the FIFISH V-EVO grab heavy objects like a lost anchor or a heavy tool?
The arm is designed for precision, not brute strength. It’s best for objects you can lift with one hand, like a wrench, a phone, or a small specimen. Trying to lift heavy items risks damaging the arm’s servos or losing the drone. For heavy salvage, you’d need a much larger, commercial-grade ROV.
How do I maintain the robotic arm after use in saltwater?
Rinse the entire drone and arm with fresh water immediately after every saltwater use. Pay special attention to the arm’s joints and the gripper. Dry it thoroughly before storing. Some owners recommend applying a silicone-based lubricant to the moving parts to prevent corrosion and keep the jaw moving smoothly. Check the seals on the arm’s motor housing regularly for wear.
Is it legal to retrieve items from shipwrecks or protected areas?
No. Laws vary by country and region, but in most places, removing anything from a shipwreck is illegal. Many underwater sites are protected by heritage laws, and taking artifacts can result in severe fines or jail time. Always check local regulations before you fly. Marine protected areas often have strict no-touch policies. When in doubt, take photos and leave the object in place.
Can I attach third-party tools to the V-EVO’s arm?
The V-EVO has an attachment port near the arm that is designed for integration. This port can be used to mount additional lights, a laser scaler for measuring objects, or a small hook or claw for specific tasks. It’s not a universal fit, so you’ll need to check for compatible accessories or be prepared to do some light modification.
Final Verdict: Is the V-EVO Worth It?
The FIFISH V-EVO is the best option we’ve found for turning an underwater camera into a working tool. The precision of the arm, combined with the stable platform and excellent vision system, makes it a genuine asset for marine professionals and dedicated hobbyists. It has limitations in lifting capacity and depth, but for its intended purposeβinspection, sampling, and light retrievalβit performs exceptionally well. If your work or passion requires you to do more than just look, this is the drone to get.
