Underwater crabbing for crab nets

Was wanting to attach a camera onto our crab net. Will need to be waterproof and ideally wifi connection as we want to see what's in the water live.

Other things in mind would be taking the camera when we go scooping and snorkelling. We do a bit of free diving to catch crayfish as well.

The DJI osmo action 4 looks promising but not sure if I should get something cheaper in case I lose it in the water throwing the crab nets into the water ?

Thanks guys !
