Here is the link to download GPSLogit - up to version 1.11 now

I have installed in on a $49 Sony Experia E1 and the app seems to work well but haven't used it on the water yet.

The 920XT Garmin watch looks nice and solid, but $549 price tag put me off. The Vivoactive one is cheaper but doesn't do 1sec logging.

It that the total cost to obtain one of those Sony phones? If so I will certainly get one tomorrow! Are there any catches?

Another session with GPSLogit 1.2, bloody amazing how it allows you to tune for the optimum course angle and speed by listening to the audio readout. Can't imagine not sailing without it anymore, lets you maximise your sessions without looking at the screen. Check it once an hour to see the 5 x 10s average. Even better when you can play all the greatest Aussie hits from the last 40 years through the earphones. Somehow the music motivates you to go faster and the speed readout confirms that you are! Mega app Manfred, well done for all your hard work creating it. I'm using a X-1 Audio Amphibx waterproof armband to keep the phone dry, no problems so far. http://www.amazon.com/Waterproof-Sweatproof-Music-Enabled-Discontinued-Manufacturer/dp/B004BU8F6G

Roo, i'll have to try the headphones on the water. good idea.

The phone was $49 outright. It did include an optus sim card but i havent bothered activating it. The phone runs fine without a sim card but obviously you can't make calls/sms etc! I hooked it up to wifi at home to download the app, and transferred the GPS log file across to my PC via USB cable.

I bought it at the local Dick Smith, but looks like you can buy online as well.

I just got back from the local Dick Smith shop with my very own Sony Experia E.

I was about to activate it but now I won't bother. At least not now.

This may be a bit of a learning curve for an Apple phone user but I can't be much dumber than the average.

I will report on how I go.

Roo's report of the usefulness of the earphones speed talking is one of the holey grail features we talked about years ago. Despite trying really hard, Tom could not interest Locosys in it at all. In many ways, these phone devices are far ahead of the dedicated GPS's abilities in many ways. It's a pity none use a GPS chip that records the accuracy data (that I know of), but it stucj me that it might be possible to use a 5hz or 10hz Bluetooth UBlox based dongle to get the GPS input in the way that Roo and Chris did in the past with Palm Pilot computers. That would be really something!

James and Roo, you're making a very good case between you, guess I'm going to have to join you.

The 15 second difference seems to be from leap seconds. The GPS time was defined in 1982. Since then, 15 or 16 leap seconds have been added, so the "raw" GPS time is 16 seconds ahead of the correct time. Seems the Canmore does the leap second correction for the displayed time, but not when writing data files. Seems Android phones have had a similar problem for a number of years (see www.zdnet.com/article/the-time-displayed-on-most-android-phones-is-wrong/).

If you want a better overlay of the tracks in GPS Action Replay Pro, you can use the "Time Shifting" function in the "Tracks Toolbox".

Only if you're doing a "regata" in gpsarpro.

I'm using the regular one that I linked to, just ordered another and headphones to have as spares. No brainer getting this setup, more features than the stand alone gps we've been using for years.

Saw this on facebook:

http://shop.gps-speedsurfing.com/p/67/thingsee-one-gp3s-edition-v1
Available for pre-order - 299 euros - 450 AUD.

From the website:
The Thingsee One GP3S Edition V1 is based on the Thingsee One. It has two important feautures to make it suitable for GPS-Speedsurfing.com.
- It run's a custom firmware developed by GPS-Speedsurfing.com enabling 10Hz RAW Data-logging in .UBX file format. The data stored in this format has the highest quality for Speedsurfing and containts 10x more data-points than the GT-31.
- The Custom firmware will show your AVG Speed (5x10s, 2s, 100M, 250M, 500M, Nautical Mile, Distance, Time) on the display so you can check your progress on the water easy
- When connecting the USB cable to your Windows or Mac computer you simply access it like a remote USB device and just upload the .UBX directly to GPS-Speedsurfing.com
- The GP3S has a custom display, this display makes it possible to read the data on the water even in sunlight an mosty conditions (The standard Thingsee has a much darker display, makes it harder to read it on the water)

The development of the firmware will continue in the months to come, and we will publish new builds on a frequent base, enabling new features like Wifi-upload, Live tracking by Mobile Data and others.Please note that the Thingsee is Weatherproof and you need an aquapack or equivelant to use it on the water.More info about the Thingsee can be found at thingsee.com/thingsee-one/data-sheet
Pre-orders will be shipped in 6-8 weeks
