The VT4 was everything it is claimed to be, but I have only used it for a week. Plenty of options but well organized and customizable so that you get your screens easily when underwater.

Main quibble so far is that the compass calibration is not as quick as I would have thought.

Love the product! I am a new diver and it worked flawless on my first dive without my instructor. Thank you Oceanic for making a solid product and making me more at ease on my first out of the class dive! Best of all it is a cinch to program and the large backlit screen is easy to read. I read some reviews about having issues with the transmitter I did not experience this at all with my dive. However, once I uploaded my dive log to my computer it showed me that it had loss signal at 55 feet. However, this was only for a brief few seconds and it picked the signal right back up. I like that I didn’t even have to re-sync the transmitter.
