I used a Galaxy S3 when I got back into sailing. It was a long way out compared with GPSTC devices.

Hey segler has anybody written a GPSTC divisions firmwater for it? ie alpha, nautical mike and hour

Not that I know of. I have never checked since I don't need to record speeds that anybody would consider official. I use it only to archive my own sessions. It does a great job of that.

The reason Decrepit asked, I assume, is for 'on the water feedback' of the GPSTC categories when using a Motion Mini Logger for recording data for posting to the GPSTC. Such an app is available for many of the Garmin Watches, but if one was written for the Timex, it could obviously be a much less expensive option.

OK, thanks. I understand better now. My Timex allows for some programming of the on-water display in real time while out sailing.

I have mine set to show elapsed distance, real-time speed, and time of day in three easy to read lines. It does not display track or alpha, but it does record track. Each session is saved as a "workout" file every time you start and stop the gps.

Then, after ending and saving the session, it can be programmed to display all sorts of things. I have mine set to display, among other things, total distance, total time of the session, and maximum speed of the session (these are what go into my paper logbook).

When you upload each "workout" to the Timex Connect app (Windows only), all data are uploaded and displayed, including a bunch of charts, such as speed over distance or speed over time; this includes the gps track superimposed on a map. Quite nice. No, there is no function for alpha in the app or on the watch.

The Timex Connect app keeps all sessions in the cloud, but can also upload to such workout sites as strava. I archive my sessions in strava as well as my paper logbook. Then I delete all "workout" sessions on the watch to keep the memory clean.

If you use Mac or Linux, you can upload the .fit files directly from the watch to strava.

A lot of useful functionality for a cheap waterproof watch that collects gps data indistinguishable (to my old eyes) from the GW-60.

No. Nothing custom on the Timex Ironman GPS watch. Only what comes already baked in, which is already perfect for my needs. This is part of the simplicity that I like about it.

For more custom stuff, I ordered a Garmin Vivoactive 3. They are down to USD$99 on amazon, formerly USD$250.

For 10 second, 2 second, alpha, and such, I just use my GW-60.
