Keep it, dive it and enjoy.I just bought a Petrel 3 from Dive Right In Scuba. I needed to upgrade from my Garmin Descent when my eyesight started to fade. I figured go big and see big. Well I took it on 6 dives in 2 days and realized this is way more computer than I need.
This^^^.How much is the price difference? What are you hoping to gain?
