oceanic vt3 new computer user need help.

[danieldale]

asking for help ,have Oceanic VT3.Manual shows how to navigate the computer which I can do,but am unsure (never used a dive computer)if I need to change my maximum depth each time I dive OR when I go to dive plan mode do I select i.e. 50' and will it control my dive from there;if thats the case.Does anyone know of a dive tutorial for a VT3.Could not find one on oceanics site which would probably help.Pre thanks for help

The dive plan mode doesn't actually change any setting. Nor do you have to set a maximum depth.

The dive plan mode just lets you know how deep you can go and stay out of deco. You'll notice that after your first dive it'll tell you that you can't go nearly as deep on the next dive and stay out of deco. That's about all it does.

That said, the computer may have a "Max Depth Alarm" that you can set to whatever value you want. If you exceed that depth it'll beep at you incessantly until you come up a bit. At any rate, this has nothing to do with the Dive Plan Mode.

The maximum depth setting is only for the alarm to activate.
This doesn't have any other effect on the computer.
Planning mode is just to inform you of the maximum time you have on your next dive. So when you select the depth it tells you the max time at that depth. As charlesml3 stated it has no effect on the programming of the computer.

The maximum depth alarm is just an alarm that goes off whenever you get close to the depth that you've programmed into it. It has nothing to do with the recreational limit of 130-ft, or anything else.

Because it's an air integrated computer, I programmed it to compute air consumption in a way that by the time I ascend, did my 3-minutes safety stop, surfaced and still have 500-psi reserve in the tank.

But things like turn-around alarm pressure setting...if I can't look at my gauge and see that it's 1500-psi or 1000-psi or whatever the pressure setting that we've agreed before the dive as turn around pressure...

The dive computer is there to assist the diver and not the bible for the divers to blindly follow by. I've seen people who put their entire faith into the computer and glue their eyes to these contraptions instead of paying attention to their surroundings and their dives.
