From ELLOCODIABLO: I vote spg. Have never seen one fail. Have seen AI fail. Having a redundant comp to me is mandatory . I run 3. 2 in dive mode . 1 in gauge mode with a set of dive tables.

Had a dive buddies AI computer fail in Roatan, dive op had nothing to loan her, I had a second computer to loan her. The only saving grace is we had done a lot of dives together and her air consumption was always within a 100 psi of mine so we just cut the dives short and she came up on my long hose.

At least have an SPG on a hose in your kit
