Boy, I can't say enough about this great sub-$300 computer. My one gripe is that once you are in the log setting, it seems you have to go through all your dives (40 hours worth) before you have a chance to exit and get back to another screen...unless you do nothing and wait 1.5 minutes. I can't find anything in the manual that suggests there is another way to get from the last logged dive (for example) and get back to dive planning. Am I missing something?
