Shearwater GF contacts problem

spunkmire

Hello,
I am using a 2nd-hand Shearwater GF. When sea diving, it won't turn off afterwards (the "turn off" option isn't there in the menu list).
Only after soaking it freshwater will it turn off, and then it turns ON again when in my damp dive bag,

1) Where are the on/ off wet sensors?
2) How can I get it to die? Will turning it over and getting the underside to dry work?
(N. B. if is salty it cannot dry completely and will always be damp because of the salt).

3) Anyone heard of a Shearwater Pursuit for under £600? Any condition accepted.

Wet contacts are clearley visable under the wrist strap.

Its the wet strap that making it turn on.

I used to have problems with it not switching off but swabbing the contacts with kitchen towl sorted it out.

Have you done the software upgrade? i thaught they sorted out the pezo button issue? Thats whats stopping the unit offering the turn off function in the menue.

Talk to Bruce.

I had the same problem with mine.

I removed the stainless mounting plate and cut a couple of pieces of inner tube to fit under it then fitted the plate again. The rubber makes the mounting plate stand off from the bottom of the case so that water drains fully away and doesn't gettrapped in there.

Cheers,

Stuart

I thought it is the wet sensor that won't let you turn it off - at least, my pursuit won't offer the turn off option underwater, so I assumed the wet contact was responsible?

I *think* Bruce disabled the wet sensor in the Pursuit. I think the early pursuits had wet contacts, I don't think the new ones have them. They use the pressure sensor to determine whether it is appropriate to turn off. I bet Bruce covers this in the manual when it comes out.

The GF has wet contacts, and uses them.

All Pursuits have wet contact. New case versions have the contacts in a different position.
Dive computer versions do not use the contacts, only controllers.
Early Pursuits have the wet contacts under the wrist strap which look like two small needles sticking out near the protected depth sensor. drying these pins will allow the menu item "turn off" to be accessed.

You are using an old GF? They are completely different from the Pursuit. Wet contacts are thre same as the early Pursuits though.

Hi All,
Thanks for all your replies.
Yes I do have an Shearwater GF computer,
will try keeping the pins on the back clean,
and do the updates. Cheers
All!
