Since you are buying a used oceanic - since that is a stock size, you can add it to a clip mount console and get a retractor if you ever get tired of it on your wrist. That would set you ups like wscdive does his. The
Quick Disconnect Compass is $49.95... but that is with the compass included... just the little clip mount shown is just 15, (compass mods are 35) so it will be easy to get it off your wrist if you don't like it that way.
Personally... I hate things on my wrist. Won't wear a compass, or computer there.
I know that is the unpopular answer... but here's my reasons:
First, I'm a kinda disorganized individual. A wrist computer (through out this rant, feel free to include compass any time I say computer - when applicable), A wrist computer is kinda big. Unless you have one of those tiny little ones, which then are too small of a display for me. A big computer (compass) on my wrist gets in way when I put on my BC. Always seems to hang up on my left strap when putting on my BC.
If I'm trying to reach under a ledge to tickle out a lobster to take his picture, I'm scratching it up.
When I get back on the boat, dock, etc... it's too big to leave on my wrist, so off it comes. An hour or so later when getting ready for the next dive you hear "Has anyone seen where I left my computer?" but I do the same thing with keys, sunglasses, dive buddies...etc.
Or walk up to the camera table, and sitting in a pile are 4 identical dive computers... all of which had slightly different dives earlier... and yours is...? So if you are doing that... Make sure you carve or write on your initials or some mark so you know which is yours.
Ok, final and most important point in my mind. Number one reason divers get hurt is running out of air. Number one reason divers run out of air is not looking at their gauge. People ask me all the time - "how do you use this computer?" "Easy... jump in the water and don't let the big number hit zero!" Really that's about all there is... But folks get a bit caught up with the computer - when on the wrist.
They're diving along and the computer says, 8 minutes left - depth 110... so they work up shallower, 20 minutes left, depth 56. If the computer says they have 20 minutes left... well they have 20 minutes left! But not if they are down to 200 psi in the tank. But I've seen divers get hypnotized, lulled into safety by having a big number on the computer.
That's why I prefer it's on the gauge (unless of course it's an air integrated wrist computer like the
Aeris Elite - I'm fine with that on my wrist, or on a retractor.)
My thought is every time you check depth and time you should check air supply. End of story. Well why look here, then look there? If splitting up the info was a great idea, why don't you drive your car with a speedometer on the dash, tach on your wrist, oil gauge on your knee... etc. Put the data I need in one spot - If I look at one - glance at it all.
To me, it's more convenient, easier to use, less hassle, and safer.... But maybe it's just my opinion....
