Buying an underwater drone often requires some research. There are many factors such as cruise speed, depth, battery life, etc that needs to be considered while buying ROVs. Even after all the research you often find at least a couple of drones falling in the same category. To help you in such situations I have tried to provide insight into two of the famous underwater drones in the general-purpose ROV category.

In this article, I am comparing Gladius Mini with FiFish V6, two of the best drones for hobby or recreation purposes. I had the privilege to see both these ROVs in action at CES 2020. Also, check out our in-depth buying guide on best underwater drones which you’ll find super helpful if you are planning to buy an underwater drone.

Physical Features

Both these underwater drones have a unique design and both look good. It is really difficult to pick one when it comes to aesthetics.

GladiusMini vs FiFishV6 Underwater Drone Let us see how Gladius Mini and FiFish V6 differ in terms of physical features.

Gladius Mini FiFish V6
Weight ~5lbs ~8lbs
Thrusters 5 6
Tether Length 50m/100m 100m
Number of Lights 2 2

Gladius Mini weighs just around 5lbs whereas FiFish V6 weighs about 8lbs. But FiFish V6’s extra thruster might help you when the water current is higher.

Both these ROVs have the same tether length and number of LED lights.

Technical Features

Apart from the camera the three major features that must be considered while buying any underwater drones are operating depth, battery life and cruise speed. Also as you go deeper it gets darker and hence you may also need to consider a drone with powerful headlight.

Gladius Mini vs FiFish V6 Comparision

So let us take a look at how both Gladius Mini and FiFish V6 stand against each other in terms of technical specifications

Gladius Mini FiFish V6
Camera 4K 4K
Lens Angle 95° 165°
Operational Depth 50m/100m 100m
Cruise Speed 4 knots 3 knots
Battery Life 2hrs 4.5hrs
LED Lights 2x 1200 Lumens 2x 2000 Lumens

As you can see, both the drones can operate at the same depth but the speed of Gladius Mini is more compared to FiFish V6. When it comes to the camera, although both Gladius Mini and FiFish v6 is capable of 4K recording, FiFish V6 has a wide-angle lens allowing to capture the surroundings with ease.

FiFish V6 comfortably outwits Gladius Mini when it comes to battery life and Lights. FiFish V6 has double battery capacity compared to Gladius Mini which is very much important in ROVs. Also, headlights of FiFish are much more powerful giving you crisp and bright videos even when there is no natural light at the depth.

Other Features

There are some features that are unique in both these ROVs. It completely depends on your purpose as to what features you need. I have tried to list those features in this section.

Gladius Mini

  • One-Touch Depth Lock Mode
  • ±45° Adjustable Tilt Lock Mode
  • One-Touch Share on Social
  • Live Stream

FiFish V6

  • 6 Degrees of Freedom
  • VR Head Tracking
  • FIFISH Posture Lock
  • Quick Charge

As you can see both ROVs have their own unique feature and if you need one you are bound to lose others. So it is better to choose the one based on your applications.
