I am purchasing a Zeagle ZX/Flathead V1 regulator and I have been given the option of purchasing a Smart Com Console to replace the depth gauge on the console. I am brand new and this is my first purchase and really like the looks of a wrist computer but the deal is very good for the console. I don't want to spend the money for the upgrade and then in a few months regret not buying a hoseless wrist computer. Suggestions?
