I took it sailing today. It was a bad day. The wind was too west. First run was best with 6.2m on slalom board with 34 cm fin. The GX-52 said I peaked at just over 38 knots! Changed to speed board immediately, but the wind died and swung too far West again. Skunked!

Got back to find NO LOG in the GX-52. I am starting to get a bit Pissed off!

I can't see any reason why it didn't log. The Genie recorded my speeds on the display, but no log file. Oh well, back to studying the set up guide! It should not be that hard.

I found setting it up in the utility much easier, but the logging does seem to change by itself. I was sure I had it set on 5hz yesterday, but the utility said it was off. Today when I plugged it in early to make sure it was logging, the utility was on 1 hz but the file is definitely 5hz.

No distance readout that I could find either.
I asked Locosys and Tom about the History Max scrolling through months ago. They kept fobbing me off and avoiding the question. No I know why! Not good enough!

I got mine to log today. It seems that there are problems with the Utility. It does not seem to talk to the GPS settings. I had to use the GPS screen to turn logging on and adjust the HZ rate. On the screen there is no option for smart logging. Another bug methinks.

I logged everything at 5hz today.

A couple of observations.:

-5hz give slightly better speeds.

At first I was a bit worried when comparing with the GT-31 results, but then I realised I should have expected this. Logging at 5hz means the software can find a slightly faster section in a normal speed run due to its higher resolution.

Peak speeds on the 3 GT-31's were a few hundreths of a second under 45 knots. peaks speed on the GX was 45.08. But the 2 second speeds from GPS-Results and RealSpeed were almost identical, so it's not a biggie.

My best 10 sec on the GT-31 was 43.96. On the GX-62 it was 44.18.

- The screen font is slightly smaller than the GT-31. I can read it fine when I stop but it is harder to read on the go.

- The SDOP strength bar on the screen is pretty well useless because it does not show up when the genies screen is showing. This means the only time you could see it is before the first run and after that, while you are over the Genie speed.

-I was running it for about 3.5 hrs. The memory was almost exactly half full when I downloaded.

- The file is SBP. No satellite position and strength in the file, but I guess the reasoning is that it is not needed with SDOP values. I don't agree. The number of sats fixed on is logged. Not sure about this.....

- The use of the Menu relies on pure memory. One has to just memorise the touch combinations to manipulate the settings and review your runs. Not good for the memory challenged like me. Maybe it will finally sink in

- as already mentioned: there is no on unit setting for smart logging, and

- the GX-52 Windose utility does not seem to communicate the settings to the GPS unit, and although it seemed to write the username to the unit OK, it actually didn't. and

- There is no distance readout on the screen. Correction. There may be a distance readout. I just looked at the set up manual and notice that there may be a distance readout in the genie speed review function. After scrolling through the 'Max' speeds and then 'Max 10 sec' speeds, the next screen shows the Time, Date, GPS location coordinates and maybe the distance. Mine has reset to blank so I will have to check this next time I use it. It is super tiny font though.

- You can view the top peak speed list and 'N' second (10 second) list in the utility, but you can't save it to your computer like with the GT-31.

- The Utility seems to make and save a KML file OK for track viewing in Google Earth.

- Although fiddly in that it requires physically plugging the GPS into your Windows computer via USB and opening the utility, the actual download is quite fast. It took only maybe 10-20 seconds for me.

Thats about all I can think of now.

OK, took the unit for a smart logging test today and it failed miserably!
I think it's a Dumb Logger!

Had some fun on the water today, GW52 on my upper right arm, Gt31 on the right shoulder. the Gw52 gave me a max of 28.63 the GT31, 28.18.
Was looking forward to checking the files, especially what happened as the smart logger changed frequency in the middle of a gybe.
BUT nothing was recorded today!!! The file was still full of what I did on the 10th. So to check whether this was caused by a full memory or smart logger selection, I deleted the memory, and took the unit for a drive to the shops, had 39.5 on the display, but an empty data logger. So then changed from smart logger to 5hz, went for a walk round the park, and had a successful recording.

I suspect that the smart logger function hasn't made it into this firmware, that's why you can't select it from the unit, and when selected from the utility, the unit doesn't know what to do, so it does nothing.
Tomorrow may bring us a bit more wind, so I'll have another go at 5hz.

how about creating a topic just for the GW (or GX ) 52 ???

I was thinking exactly the same thing, but was going to start it when I'd finished my tests, and could be positive about what's going on.
But perhaps I'll start one with today's strange results, once I've figured out what's caused them.

I have been wearing a "TomTom Multi-Sport Cardio" GPS watch on my wrist and a GT-31 on the top of my head over the past couple on months when windsurfing. Below is a comparison of GPS results from 9 windsurfing sessions. It seems the TomTom always underestimates the GT-31 results by 1 or 2% (double that for distance).

Well throw that TomTom in the bin if it's making you slower

Will the powers to be, looking at the garmin 920 xt ,now that the software has be modified to suit windsurfing, kiting.
Looks to be a good replacement if it fits the criterier needed.
Cheers

Manfred tells me there is a new Beta version of GPS-logit for android that can do live uploads to websites, maybe KA72! That is very interesting stuff because it means there is potential there to update results for events like the Defi or the Barrum Heads etc as they happen. Manfred is seeking as much feedback as possible on the performance and accuracy of the app in different Phones. Email your findings to info@gps-speed.com

Sailquik the info I was looking at was posted in the gps and speed talk thread under
Garmin 92oxt windsurfing activity.
Fin 151 has done the mods by the sound of it.
Cheers

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

www.gps-speed.com/gpslogit.html

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.

www.dicksmith.com.au/prepaid-mobile-phones/optus-sony-xperia-e1-pre-paid-dsau-em5286

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.

That's very interesting!!! I've just checked it's specs and it says.

A-GPS, GLONASS

under GPS, never heard of Glonass before, checking reveals it's the russian alternative to gps.
This seems to say it's using both????

Took my new Canmore for a drive with my GT 11.
I had thought the GT 11 was pretty good positionally but on the roads it clearly continues beyond the point where you change direction which must affect the validity of alpha results. The Canmore was consistently better in this regard and followed the driven track much more closely. This seems to mirror the experience Mike had with his trials when comparing the Canmore ,GW52 and GT31.

As I attempted to point out before: The offset error of the positioning should have no effect on alphas unless it changes drastically during the run, which is quite unlikely.

Manfred's latest version of GPSLogit 1.2 works brilliantly. The voice readout of the speed and maximum for the leg you have completed makes a huge difference. I play it over a mix of 80's Aussie hits I have loaded on the phone. It starts giving the speed once you hit the speed threshold set in the app, I use 25 knots. With some great tunes playing through the headphones and the speed readout it makes it easy to adjust your course and bring up the speed. It also tracks the best 5 x 10 secs and has a readout on the screen.

So maybe a GW52 on the head for verifable 5hz data and an android phone for instantaneous feed back.

Just wondering, Optus have a sony $30 prepaid for $49. I guess you need to spend the first $30, but then what happens if you don't recharge at the end of the month?

I like the Vodafone $30 for 365 days, it cost more if you use the allowance quickly, but this phone would only be used for emergency calls. I think the sony is available for around $100, and at that price I'd trust it to just a Paqua without ziplock bag, that way it may be readable if it can be shaded.
