Yeah, I bought one and have 6 freshwater dives on it. The display is large and very easy to read. It's so easy that your dive buddy can probably see the display. In fact on a few dives, Aquamaniac read the display just looking over my shoulder without me even knowing it.
The user interface it very easy. Everything is menu driven. A big plus since I didn't want to be carting out the manual all the time. The battery is user replaceable, although I have a ways to go before I need that feature.
There are three buttons which control it. They are easy to push even with gloves on. The unit is always on, telling you the time. When you hit the water it switches to dive mode and actually starts counting time.
The wrist strap is of decent length that you can easily fit it on top of a wetsuit. For those who want to replace the strap with bungees, you'll have a bit more work. The strap holes are small, barely big enough for some fishing line so you'd have to do some fishing line/bungee combo or drill out the holes.
The only thing I miss (well not right now, but maybe in the future) is a gauge mode - it doesn't have it. Although someone mentioned you could put it into 50% nitrox mode and you'd get something equivalent. I'm just ow certified so this is all beyond me. So this computer will grow with you through air and nitrox non-deco diving. It hits its limits when you progess to deco and/or trimix diving. My personal plan is to move very slowly through the diving certs so it will be some time (or never) before I get to trimix.
Don't have the pc interface yet. I'm waiting for DiveInn to get it in stock.
I like the computer. It's so easy to use that it's blended into the background with all my other stuff.
