Ok, got my new VT3 today. Talk about excited!
Unfortunately, I'm going to disappoint some on the functionality, but it's a minor issue that will raise some questions for some. Please keep in mind, I have yet to dive it, this is an issue straight out of the box and in the manual. These things have been verified by Oceanic's Tech department.
1. Manual activation: Once the VT3 is activated manualy, it takes 2 entire hours from the last button pushing for it to shut off automatically. 10-20 minutes is reasonable. 2 hours is flat out ridiculous and should be corrected to help conserve battery life.
2. Wet activation: Once a dive has been made, the VT3 will remain on for 24 hours. It becomes "locked" in a specific mode for that time frame. Again, this is absolutely ridiculous and should be corrected or set up for a manual turn off/on. I can understand the unit being locked if an extreme violation is noted on the computer, but it stays in this mode after a normal dive according to the manual and the tech department.
3. No way to manually turn the unit off. Why?
4. The manual boasts that battery life is 100 dive hours, but it does not include information on what an actual dive hour is for this computer, nor does it state how the "locked" 24 hour mode and 2 hour self-shut off effect the 100 dive hour life. Why?
I know someone will eventually raise the issue that features 1 and 2 are designed with emergency services in mind just in case of a dive accident. Well, if you think that you need to think again. How many people carry their manual with them for their dive computers, very few if any. Then, how many emergency services folks will take the time to figure out how it works and scroll through the information, absolutely none unless you're already dead; saving your life is way too important for that immediate moment and time will be crucial.
So I pose the question as to why features 1 and 2 in my post exist as they do not make any logical sense. If a unit goes unused at the surface for 10-20 minutes, it should shut down, unless connected to the d/l kit and software. This will conserve battery power and save divers money on batteries and hopefully create less batteries in the garbage.
Now for the good:
1. Extra protective face shields are available= part # 04.8220 VT3 Cover
2. Transit clips are available, but currently on backorder due to demand
3. Compass mounts to add to the transit clip are available, but currently on backorder
4. The band is long enough to quite possibly fit over a hard suit!! (really long!!)
5. Backlight is quite adequate in low-to-no light and won't kill your night vision
6. Easy to read display, even through the protective sticker (ha!)
7. Cool dive plan features: turn-around/return pressure alarm, max depth plan alarm (can set manually), dive time remaining alarm (can set manually), end pressure alarm (can set manually), safety stop alarm (can set depth and time manually).
The VT3 Complete came packed in a case much like the Pelican hard cases, and lovingly surrounded in foam to protect the transmitter and computer. For those who feel the need for a pressure relief valve, there is not a Pelican case that the foam will simply slide into perfectly, so you'll need to buy one that's near the right size and use the pull-foam to fit it. There are so many user programmable features that it will put a grin on your face to see just how versitile this unit truly is! I can't wait to get this unit in the water! In fact, there should be a special certificate if you manage to use all the features at least one time legitimately (I know I won't be able to).
