If you are using an aquapak (which you should for either GPS), the biggest issue is the track logging. The foretrex logs 10,000 points, thus recording your whole day.

Also, most users on GPS-speedsurfing are using the foretrex, just so that there are no questions as to the legitimacy of the track logs.

Hi Harrow The Geko 201 has a similar chipset to the Fortrex.
It also stores 10000 track points 20 routes and so on.
But the Geko 201 is the same price as the fortrex 101.
I would go for the Fortrex 101.
dont forget the aquapac with arm strap $50.

Mk7 I had the Etrex which is alot different.

Looks like the new AquaPac Pro Sports Mini is the one to buy. Yes? MapsDownUnder sell them, but they're in Victoria, so I want to be sure it will fit !!!!

Harrow, my understanding is that the "waterproof rating" is not much more than a standard test method, eg, submersible for 5 min @ 1 metre or whatever, rather than an actual indication of its actual performance. My Magellan Meridian GPS has the same rating as does a lot of other so called waterproof electrical equipment. You've got the right idea using an Aquapac. Even though they say these GPS's are waterproof, the water pressure acting on the seals is a hell of a lot higher when wiping out at speed, compared to holding a GPS stationery under water for a certain time. If I were you I'd treat them as though they are really just water resistant and let the Aquapac do the work.

Unfortunately no arm band.

I have been using the strap from an old Ronstan start watch, but it wouldn't be to difficult to make one. There are slots to thread a strap.

Whitworths in NSW have the Boxit cases.

The boxit has slots, but no armband. It floats as well

G'day Harrow,

I have the Geko and have found it a good unit.

I use it in a aquapac with I bung down the front of my wet suit (between my man boobs).

I actually get less dicky readings with it there than when I used to carry it outside my wetsuit.

I have found that with the Buttons on the face of the unit it can start doing things by itself and have had my max speed reset a couple of times.

Myself I wouldn't get a strap-on GPS as me and the water regularly embrace each other at speed and as Tony W from Sandy piont recently found you can lose the lot quite easily with a crash(including the data for a possibly best this season session).

GPS's are great for taking the bull out of speed sailing and can be great tools for improving technique and setup.

But..Be warned!!! GPS's are EVIL, ya crack your PB's for the first 6 months and then you spend the next year trying to better them by 0.1knot

Haaaa, yes I can see that coming a mile off. Actually I was hoping it would make me a better sailor, since instead of backing off during the gusts in Botany Bay chop, I will be cranking the sail in!! Anyway, as long as others get some joy from observing the impending wipeouts, it will be worth it.

By the way Elmo, have you tried any of the Geko's built-in GPS games while sailing? The snake game could be a lot of fun on a one design!

Chris, The only diff between the 101 and the 201 is the in built battery. So far I haven't had trouble with the mini-walkie aquapac.
And they do come with a 3 year Warranty.

So ........... are the Foretrex or Geko suitable for the casual sailor that just wants to know how fast he can go ? If so where would best place be to buy these from ?
