What is the ‘Depth Rating’?

Depth rating is the maximum depth the torch can be taken too and not flood (i.e. leak water). 

Leaking water is normally considered catastrophic failure for a torch as it causes corrosion of metal parts, short circuits electronics and damages the battery.


This is usually tested using a pressure chamber/pot, to simulate the pressure at the target depth.
