I applaud Gary and Disco's comments.It is NOT a snorkle it is a RAISED AIR INTAKE designed to let the engine breathe cleaner air in dusty conditions.
Ignore the maximum depth warnings at your peril.
We ALL know Land Rovers will if used correctly drive through deep water but remember it is not just keeping it out of the engine that is important. There are a multitude of electrics you need to worry about.
ESPECIALLY the 100, ECU in seat box and potentiometer for accelerator to mention two of them.
As a rough guide use the top of the wheel rim as a guestimate for SAFE water depth.
