Being a new diver this is my very first computer and all can say about it is... wow! Very well designed both ergonomically and functionality. It's easy to use, especially if you have someone like Martha or someone at the store showing you, that was actually the only *bad* thing about it, the manual makes you feel you need to go to college to learn how to work with it, lol... but once you have someone showing you screen by screen which won't take more than 10 minutes, it's a whole different story.
The larger display make it easy to read and use in and out of water, and of course one of my favorite being able to download all my dives info directly to my pc into a very friendly user software interface than contains all the data needed and more to log your dives including graphs that show your depth minute by minute, descent and ascent rates which has been helping me my improve my dives tremendously!
What else can I say....Sherwood pulled out all cards on this one! Highly recommended!
