ROV attempted to move the magnet by both pulling the Atlas arm, and thrusting with full thrust in all direction. The magnet did not move.

We use magnets mainly to moor to ships stopped at sea. I tested the magnets in various conditions and
I must say that the Willy 800 is excellent.

The Willy 800 kg | 1750 lbs is by far the best diving magnet on the market.
