Qysea added better gear and new tools to its underwater drone, the FiFish V6, to reveal the V6 Expert. Like the standard V6, the V6 Expert has six thrusters for 360-degree movement and the ability to descend to a maximum depth of 328 feet (100 m). With a forward speed of 4.9 feet per second, the V6 Expert comes standard with a 4k/30 FPS camera system with 6000 lumens LED spots. Thanks to a more robust body and a larger 156 Wh lithium battery, it can be used for up to five hours on a single charge. When you want to reach unlimited diving time, it also has the necessary infrastructure to connect it to an optional external power source. In cases where you do not have the opportunity to connect it to an external power source, the time you will need to charge it up to 90% is only 1 hour. What really makes V6 Expert different is; It has a port that you can use to mount tools ranging from a robot arm, sonar module, water sampler, navigation system, and laser rangefinder.
