Here’s a new one! The Cressi Digi 2 is a simple but very precise instrument that will keep track of your air pressure digitally. Making it much more accurate than an analogue manometer, a copper spiral through which a hole detects the pressure and offers the reading in a sphere moving a needle.

It also acts as a depth gauge, dive timer and water thermometer all encased in a surprisingly compact size with a great compact price. Say good bye to your cricket bats and hello to the Digi 2!
