| Gekko
As a first computer a Gekko is great for the price.
I thought the only difference between them and the Vyper was the PC interface? If you don't want to download your dives to you PC, then there is no need to pay the extra.
My Gekko took me from beginner, through Nitrox and right up until I started technical - now of course it is pretty much redundant, but it's still working! |
