To my knowlegde the bilgepump motors can only take a certain amount of pressure about 30 m. Because the pressure will push the bearing that is located around the drive shaft.so hard that the driveshaft will stop.and this is only hear say.i hope somebody knows better and can prove me wrong.so i wont ...

Checkout dive store online.search for manometer.its an analog gauge.divers use to read depth.its accurate and reliable,but,you have to keep it in reach of the camera to read it

If so very cool.getting it watertight is easy,but making it so it can withstand waterpressure is much harder.how deep can you go? I was hoping to reach 50 m ,even though my bi...

Meters I use dc current.will i loose much current if my tether is 60-70. Meters. Its either tether or wireless .wireless is more demanding regarding waterproofi...
