How much does the FiFish V6 cost?

Quick answer

desde ~1.600 $

The FiFish V6 is the best-known consumer underwater drone: a ROV from QYSEA (Shenzhen) with a 4K camera, six thrusters that let it move and rotate in any direction, a 100-meter maximum depth and about 4 hours of battery, from around $1,600. You pilot it from the surface through a cable, even with VR goggles that track your head. It is teleoperated by design: radio doesn't travel underwater, so here the cable isn't a limitation, it is the category.
