It seems as though everyone that has given their opinion so far owns a cobra or some other suunto product which will tend to skew the responces towards suunto or more specifically the cobra. No problem with that as suunto makes excellent products, but I have another view. My first computer was the Sherwood Wisdom and I love it. Large display, many different settings and functions, nitrox compatible, all in all a very customizable computer for whatever kind of diving you may be doing. Now I just recently got the cobra 'cause I have to have a suunto product for teaching(shop requirement). Now I'm not complaining one bit. The cobra is an excellent computer and it does everything the Wisdom does. The Wisdom, in my opinion however, has two advantages over the cobra. First, the display is much bigger and is easier to read(this may or may not be a factor for some but I thought of it as an advantage). Second, the Wisdom has more user adjustable functions like turn around pressure, minimum ascent pressure, and end of dive pressure. These functions are all adjustable by the user where as the cobra does not allow the user to adjust these and even has one less function(no turn around function). Again, some may see this as an advantage or disadvantage. The Wisdom also has two buttons as opposed to three but I don't think that is a factor either way. I like both computers about the same. There's just a few fuctions on the Wisdom that I liked that the cobra does not have. This may be an issue for some and others not but you really can't go wrong with either choice. Oh yeah, the Suunto is the more popular brand by far and is much more likely to be serviceable wherever you go where as the Sherwood might be more difficult as far as getting service. Depends on where in the world you are.
