I'd stay away from the Wisdom. It's not a bad computer...when it works. Mine went bad a couple of months ago. Sherwood did replace it, but I also found out from my LDS that Sherwood said they've "been replacing all the Wisdoms that do that." Sounds like it's a common occurrence. My LDS owner had the same thing happen to his promo model on the 3rd dive he did with it. If I had to do it again, and went with a hose console, I'd probably get a Suunto Cobra.
