What sort of life do they have? ( If you don't drown them ).. I've had mine for 18 months now so wondering if it's likely to die - done c 2800kms..

No Sue, GT31s are out of production, there's still a few around but you really have to hunt for them now.
As Mineral says, they don't wear out with Kms travelled, I've had my GT11 since 2007.
The battery doesn't last as long as it did back then, but I did a 7hr 200km session with it last month with no problems.
The main thing is to keep salt water well away from them! Don't open the pack with wet salty hands, dry them well first.
I've seen guys open them out on the water, because the joystick is hard to use in the pack, these units had signs of corrosion on the screws in the card slot, and shortly thereafter, would not recognise a card.

Ok. Good. Hope they have a replacement when mine dies although it sounds like I'll wear out first.
200kms in 7 hrs! Don't know how you do it!

Hmm, now you put it like that, I've had a proper look. GPS was on for 8hrs but we sailed for 7.
Secret is flat water, much easier and faster sailing.

Mmmmmmmmmmmmmmm

Sue, for once, why don't u ask the people you sail with??

Today, you sailed Peely with Mark J........who had his trailer of windsurfing gear.........yes he was selling GT-31, Blue tooth,

I bought one, today, at Peely......................

I didn't know he'd be there. I told him if I had known I would have got a whinch from him!
Not sure if I want to get another GPS at the moment as mine still works fine and I've just spent $ on a whinch + formula line...
I'd just heard rumours you couldn't get them anymore.I assume there will be others you will be able to get that will do the job if the 31's aren't available..

I found it harder to find a 2 Gb SD card.
Got it from Ebay, then postage took about 3 weeks (from Syd to Bris).

I hope Laurie don't mind - not that I'm gonna get rich selling this :)

But if anyone is stuck looking for 2gb SD card which works with the GT31, my business www.netplus.com.au have them in stock.

A micro SD works with the adapter

Yep, one of our guts is using a micro with adapter, but initially it was very stiff to get in and out, (woops did I really say that!). So it was hard to tell if it was properly seated, if it wasn't it would work loose during the session and stop recording. Don't know what he did, but it's ok now.

Yes Decrepit , my Capt'n, that would be me, WazzaTechnoIdiot.
The carrier was very stiff so I solved the problem by tossing it in a bin and getting one that clicked in nice and easily. I was worried about damaging the GT31 otherwise. The one I have at present is a (Pro)Master carrier with 2gb SanDisk card. Because the position of the slot, apparently designed by a chimpanzee, it is impossible to grab hold of the carrier to get it out unless it "springs" out of the slot when you click it. For this to happen the carrier mustn't be a tight fit.

I bought a GT-31 from WS & S today and they only have one left.
Sam said they are not making them any longer so if anyone's thinking about it,don't delay.
