Re: [PSUBS-MAILIST] Barometers

A standard barometer is just fine. 
Read it during closing the hatch - and adjust the "stay" arrow to the number. 
Means bring both indicators to the same figure.
If during the dive the barometer indicator increase this means you have a gas leak in your sub..
To much oxygen flow or a leak in the compress air system.
