From meltonart: If you dive a computer have a backup and analog pressure/depth gauge. I don’t have one currently but am adding to my gear/kit asap. I estimate about 90% of all the missed dives I’ve seen on boats have been related to computer problems.
If you have a back up computer it needs to go with you on repetative dives, not sit in the save-a-dive kit. Both need to be using the same profile and both need to be set for the same % o2. Problem is I have had both die on the same dive :(
If you have a back up gauge you need to have the tables with you too and know how to use them!
