Hi I am quite new on this forum but topic of GPS measuring is hot for me - I found another interesting alternative for GT-31 unit from VELOCITEK. In fact they offer pro sailing machines on their website, there is good real time demo for these units as well and they are full waterproof + optimised for real time speed and position monitoring - definitely it is interesting and worth to check:

www.velocitek.com/

1. prostart - unit optimised for start time countdown and the GPS monitoring

Technical SpecificationsSpeed Accuracy: ±0.2 KnotsHeading Resolution: 1°Display Update Rate: 2Hz (twice a second)Water Resistance: 3m / 10 ft (IPX-8)Display: 30mm / 1.18” digit height 120° viewing coneData Logger: Lat, Long, Time, Speed, and Heading recorded every 2 seconds, 30hr capacity.

2. speed puck - looks like it is good for speed surfers, too

Speed Accuracy: ±0.2 KnotsHeading Resolution: 1°Display Update Rate: 2Hz (twice a second)Water Resistance: 3m / 10 ft (IPX-8)Display: 27mm / 1.06” digit height 120 degree viewing coneData Logger: Lat, Long, Time, Speed, and Heading recorded every 2 seconds, 20hr capacity.

your opinion?

Sorry I did not mentioned that both units work with parametrs described below:
"Speed is calculated by the GPS unit by measuring the Doppler shift in GPS signals. The device can be configured to record data every second, every 2 seconds or every 4 seconds. The SpeedPuck can store up to 20 hours of data when recording GPS data every 2 seconds.

prices are unfortunately very hi... 399 for speed puck and 499 use for prostart but especially prostart looks like very professional tool for those who are keeping focused on sailing, so it could be definitely suitable for windsurfers, too.

the most important functions of the prostart device (from the manual):

Speed, compass, and distance to line updated twice a second
? Count down start timer
? Header/Lift indicator updated twice a second
? Maximum and best 10 second average speed recall

Waterproof (IPX8) to 3m

My initial thoughts are the puck looks like a nice find and seems to tick a lot of boxes, but then my enthusiasm is killed off by the price...

Maybe a bit too big to be used in windsurfing? Definitely for the pro start...and most obviously for the Puck.... They need to make a miniature version of it....

Announcement on GPSTC


<div>The Canmore GP102 is now accepted for GPSTC data recording.
The unit is limited in that it does not allow the detailed data checking that the GT31 allows.
Therefore it is recommended that if you are looking to get to the upper levels of the rankings you should be using a GT31.

<div>
To enhance the ability to check top level data it is requested that any post in the top 15 of the individual rankings is also submitted to www.gps-speedsurfing.com

<div>Each team is responsible for checking data to keep the challenge as accurate as possible. If you are uncertain about the accuracy of a track please contact your team captain or use the contact link on the homepage.

<div>KA72.com is the easiest way for most posts to the challenge to be made and further analysis can be carried out using additional software. Please consider supporting the windsurfers who have put time in to developing software.

Very difficult to see the display on Fangy's Canmore after a few runs.
Advantages of drying it out in the oven, however, include a beautiful and moist steamed fish supper .

I have read many of your posts regarding finding a suitable waterproof pouch for your GPS units. I have been using an
Overboard brand pouch for my car key and IPhone for the last few years without any leakages.

Here is the link. http://www.over-board.com.au/waterproof-iphone-case-aqua.html

I am also about to purchase a Canmore 102 +, as my first introduction into GPSTC.

Hard to beat the Paqua waterproof pouches!!

I have been using these for quite a while with no issues. Less than $5 from BigW.
Also just found out today that you need to delete the files in the Activities folder
on the Canmore otherwise when it is full the unit stops recording data.

I have been using exactly the same( branded Sistema) but found getting dealt to in the waves was enough to get water past the seal. I now use a layer of lanolin grease on the seal- not a drop gets past. I still like SeaSkips solution the best, but I am too lazy to brave the alternate life forms that inhabit my local Kmart

I mount mine on my helmet. It's important to me that I look stylish when I am on the water

Pity this doesn't have a screen

This one even records G forces imagine that in an alpha or high speed crash

Hello all!

This gps interrest me a lot!
What are the news with the FW modifications resquest to canmore? Will they put them in?

Otherwise, some people can send me .fit records please? (slaught (at) live (.) fr) I want to see what the gps record exactly.

Regards,
Alex.

I have a mate with a GT31 but he can't get it to record to the card. Can anyone shed some light? and yes it is a small 2g card. Power on/off, format etc etc doesn't seem to work or help.

Cheers Dave

Contacts inside the GT-31 could need respringing. Have done this with mine a couple of times when trouble reading card. As long as he doesn't worry about voiding warranty opening it up though. Also I've found cleaning the SD card contacts sometimes helps.

GT-31 provides power of 2.8VDC.

The following cards have been tested to work with GT-31:
SanDisk 2GB
Transcend 1GB
Kingston 2GB
PNY 2GB
Apacer 2GB 60X

Compatible/Suggested SD card to go with Locosys GT-31/BGT-31 or SD cards (<=2GB) with 2.8VDC(3.3VDC~2.7VDC) power input should work.

I have been looking but cant find where it says the the Canmore 102 is MAC compatible? Does anyone know?

Cheers

Yes, no problems.

If you want to analyse your tracks and results in detail on your own computer, there are three excellent programs.

RealSpeed: This was the first, written in 2003-4 for the first 2004 GPS speed event at Sandy Point by Mal Wright. It is Windows only. I like it a lot. It still does things that the others don't do at all, or don't do as well. It allows for virtually unlimited category definitions and parameters. Unfortunately it has not been developed and updated for the last few years and can't upload results directly to GPS-SS or GPSTC. But it it highly recommended of in depth analysis and cheaper than the other two.

GPS-Results: This one is available in Windows, Apple Mac and Windows CE PDA versions. It is probably the most up to date program and has integrated uploading of results to GPS-SS and GPSTC. It is quite easy to use and the Windows Version also is the one used for analysis and validation of GPS records. It does all the main categories and the windows version allows for custom categories. Allows for Google earth or other sat maps to be loaded behind your track map. Developed by Manfred Fuchs in Germany and used by the GPS-SS site for it's auto analysis when you upload tracks. I personally use this one the most now that I mainly use a Mac, but go to the Windows version and RealSpeed for more in-depth analysis.

GPSActionReplay and GPSAction Replay - Pro: Written by Yann Mathet in France. GPSAR was the original version and is still free. GPSAR-Pro is the paid version and has far more capability. It can do some type of analysis that the others can't related to Jibe analysis and wind direction vectors and perhaps some others. This program is Java so it runs on any operating system that can run Java, including obviously Windows Mac and Linux. It has provision for Auto Upload of results and satellite imagery behind your track map. This has a strong following of devotees, but personally I find GPSAR-pro a bit unintuitive and complicated to use the advance features. There is comprehensive documentation online though for those who wish to delve into it.

You can download and try the free trial versions of all these programs before you decide if you want to buy them.
