Had a look at the Suunto website, and it looks like there are three differences between the Vyper and the Vyper2. Firstly, the electronic compass.... I don't know how useful this really is other than giving a general idea of direction?? I certainly would prefer to do precise navigation with a real compass. Second is the introudction of the deep stop algorithm. I like this feature on my Vytec, but it has one drawback.... when you switch it into DS mode it gives you either a 1 or a 2 minute stop at half way between your max depth and the current ceiling - in recreational terms that's a stop at about half your maximum depth.
Unfortunately, what it does is also switch off the count down of a three minute stop at 6m. There's nothing tos top you doing a shallow safety stop, there just isn't a prompt to do so. You get used to it fairly quickly, particularly if you're diving with someone who has a computer that prompts for a safety stop anyway. The other option is to get into the habit of doing a staged ascent over the last 10m or so. IMHO, a safety stop is more about getting control of your ascent in that top ten meters rather than prevent any DCS issues.
The final difference is that they've changed the display, primarily it seems to incorporate the electronic compass. Here's how the Vyper looks;
and here the Vyper2;
I prefer the layout of the display on the Vyper - possibly as it's the same as my Vytec, mind you! I really don't like the fact that if you switch into compass mode on the Vyper2 that you actually (seem to, at least) lose your dive time and your no deco time displays in order to see both a general heading (N, NE etc) plus what seems to be a precise bearing.
If you want, Buck, you're more than welcome to borrow my Vytec - if I change it back to the default settings it will look and feel exactly like an old Vyper. You'd get an idea on how intuitive (or not as the case may be) it is at 30m or so.
