FYI the Cressi Digi 2 doesn't only display accurate cylinder pressure and depth. It also displays the estimated time (minutes) to 50 bar based on the current gas usage - very useful to see how gas consumption is tracking - this was the main reason I purchased this gauge. Also displays temperature information and dive time. It is not replace a dive computer since it doesn't track NDL.
have a Digi 2 myself and i love it. the accuracy is +/- 1% as opposed to a regular gauge which is +/-10%. its as good as you can get to AI without AI ( if that makes sense)
two little questions: 1) Can we use a SPG on one brand in a regulator of another brand? 2) When you have a transmitter + computer, you don't need a SPG right? Again, it does not matter the brand of the computer+transmitter if you have a regulator of another brand? thx
