Light and Gripper problem in seawater. BR2 Heavy

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?

Hi @Truls,

This is an interesting set of problems and we have not seen anything like this happen with the gripper. Would you mind shooting us an email at and we can guide you in some troubleshooting to resolve this!
