another ? for the vets.
I will get trained and own an evolution in the next 2 years.so my ? is what computer would you add to your dive kit ? as a back up.
the main reason for asking is ,say during the last part of a dive the computer on the evo fails . what are the best options ,I always dive with buddy so a safe ascent useing his comp for depth and speed of ascent {I am asuming the Rebreather is still working on manual or I have bail out to oc}and safety stops .I just perfer to be totaly indepentant of my buddy and use him or her for company and friend ship .
as I do not know the computer companys some web links would be nice.
thanks
