This is not connected to a high pressure gauge used in the first stage, can not be used in the water?Well, whats the use of it?

Hello Lin, yes this gauge does come with the high pressure hose that will connect to the first stage. It is not designed for in-water use. This is a gauge designed to be used with a compressor or for scuba repair.
hi just ordered 2 of these. Assume they come with hoses and can be used as normal pressure gauge with regulator.

Yes they come with hoses and can be used with a regulator. BUT they are not for in water use.
