Helpful info for VT3 owners

Helpful hint #1: Brought to you via e-mail converstion with Doug.

Q1. How do I go about using the PLAN mode to plan the next dive with a different Nitrox mix??? I assume enter the new gas % then look at the Plan mode for the selected depth. If different please advise.

A1. You are correct - change your FO2 and access plan mode - it will take residual nitrogen and your gas mix into account.


Q2. Does the EL level effect the dive calculations??? mine dove an EL 2 in a quarry in Louisville, KY. The highest elevation in that area is 876ft above sea level.

A2. The Elevation calibration does effect no-deco calculations. At 800+ feet, the unit is going to round up, rather than down.

Also helpful:
The strap is designed to be cut to size - you're saying that it's too long even after doing so? I prefer to dive mine on a retractor - we have one that installs on the back using the wrist strap pins - very streamlined, if you're not stuck on wearing it on your wrist. A compass may also be mounted to this setup if that's of interest. All of these accessories are listed on the VT3 page on our web site - http://www.oceanicworldwide.com/p_computers_vt3.html

If a buddy is diving an Oceanic Comp with a transmitter like the VT3 Pro set the number into your comp and use it to do buddy checks!!! This is great for that buddy team that wants to buy 2 VT3 pros and use this option... works also with the vt pro or atom.

If using the computer during a night dive, go to Set U and change the backlight time. Just remember to change back for other dives. If you want it simple, than just set it for the max value.

The backlight will remain on for as long as the button is depressed (up to 10 seconds), plus the user set duration time when released - user option of either 0, 5 or 10 seconds.

Found the pins. What a PITA to get to them so you can release the band! Mounting the transit clip/retractor takes some thought as well. Here's a couple of tips for the install for future reference:

1. remove band by unlocking at least 1 side of each band pin, then angle them and remove

2. When installing the transit clip/retractor be sure you note which side of the computer has the "cut-outs" for the band pins. Put 1 pin in the transit clip and set it in the "cut-outs", but do not lock them into place.

3. Install the pin for the other side and compress the pin one side at a time slowly sliding it down into place. Be sure you lock at least 1 side of this pin in place.

4. Compress the pin on the side w/ the "cut-outs" and fully lock the pin into place. You WILL need to press on the back of the clip to make sure the pins and seating holes line up, wiggle it around a bit as needed until it locks. (make sure if you tug on the clip to test the lock of the pins that you do it in a place you can find the pin as it will shoot out!)

5. Fully lock the final portion of the pin opposite the "cut-outs", then install the compass bracket and compass if you will be using them (these are simple install and need needlenose pliers to fully lock the pins as indicated in the directions).



Doug, Oceanic obviously spent some $$ on the glossy instructions for these parts. Could you suggest that they do away with the glossy install instructions for these parts and provide a better installation picture instead? The B&W pics are so small that you can't really use them for reference (these are currently the approximate size of a dime).
