Paqua Midi is the way to go.....I notice that they have made the neck a bit larger than the Paqua Mobile...easier to get GPS in and out. Fits either Navi or Garmin.
Do they come with an automatic fastener for people who forget to do it up themselves.....3 times, not mentioning any names ...... Danish, hairy, has horns on his helmet, apparently can be horrible.
Just picked up a Paqua midi and looks very good, great velcro strap. The best thing for me is that you have to roll/fold the top down to close so gumbies like me cant forget to the do the pack up
The only downside is that it is only water tested to 2 metres for periodic submersions, I guess time will tell ..........
I believe 2GB is the biggest it will take. Unfortunately this is only large enough for a couple of years 24 x 7 continuous logging.
Memory size is not really an issue as the GT will make very small files, they are only text, no sound, images or video. So think back to 1996 and memory sizes back then.
Just find a memory card laying around the place you got with a cheap camera or mobile phone. Thats what I did, with a 32MB card from a phone. However I'm now using a 1GB card my sister bought off eBay for $1 and $10 postage.
Yep, that's why I said size wasn't an issue.
For my distance attempt last month, when the unit was on for 6/7hrs, and I did 150km the file size was 1.5MB.
I've got a 1 gig card, every session I've ever done is on there, and it's still 90% free...
Does anyone know what the "low power" mode on the GT-31 does?
(Harrow waits in front of his PC for the typical useless response...."uses less power")

Got a GT-31 through Sunshine Coast Sailboards, they were very helpful and I was very happy with the price. Prices may be in flux now due to exchange rates with Oz $$. Will post another thread re what I found setting it up etc. Thnx all for your help
Haggar check sic-em-rex's post on 1hr problems. Towards the end of it Sailquick describes why you should update the GT31 to the latest firmware.
