I have a problem with the lights and the newton gripper. I have tested in a small fresh water pool and everything worked well. Then I tested in seawater and then all the lights began to flash when i come down at 2-3meter deep. The light is OFF and the problem is the same when it’s ON. The gripper does not work in seawater either, it works in pulses and sometime it moves a little when I use the thruster’s. Someone who has had the same problems?
