I never liked the aquapack+GPS around my arm, however gps-speedsurfing demands the doppler gps for the 'official' rankings. I sold my GT 11 and later I bought this Suunto Watch. This is much much better again, its not too loose or tight. Its not heavy. A gps watch is just better in terms of design in my opinion.
The GPS does everything, it works 2-3 sessions in a row. It displays speed, it can be used for navigation. It can even make a video of your track.
Could it be better?
I think soo, and yes I would buy the new one if these features would be added:
- tilted display: let me explain. A normal watch is used everywhere. However this sportswatch is most often used during activities. In my case windsurfing. When windsurfing (or riding a bike) your arms are fixed to the boom or steering weel, in this position it is actually impossible to get a good look at the display. It would be better if the display was orientated towards (45~70 degrees) to the arm. I know the watch would be thicker, however you can read it during sailing (wouldn't that be fun?);
- doppler gps: would be good if the GPS is approved according to gps-speedsurfing.com rules;
- an optional second bluetooth large display which can be mounted on the boom. Wouldn't it be fun to have a large display mounted on the boom. It doesn't need fancy colordisplay.
Up till now, its the very best gps I ever had. Though, functional and many options to play. If you're a programmer it might be fun to know that you can write your own apps for this watch.
