To be honest, I think GS is biting off more than it can chew...
It seeme the limited resources are to blame that the existing product portfolio is already slow to hit the market - I eagerly awaited the bicycle computer, but my Christmas money went to another purpose. Technical glitches seem to plague even products that are already on the market (gh505).
Rather than to tacle the market on all fronts and be late to deliver/being unable keep up with the competition, why not focus to pioneer/develop/obtain market leadership in just a few selected?
You can be the best at a few key products, but unless you have very deep pocksts, you can't be good enough in everything when you want to do it all at the same time.

Thanks for advice. It is frank and true.
To take off the glitch problem from GH-505, we are processing the new model, GH-505s. For sure we still mainly focus on our key technology such as SirfIV, new alogrithm on training devices and cycling computer. As our plan, they will be lanuched on Q1, 2011.
To respect customers' demand, just put more features on current/ furture products likes Windsurfing/ Surfing function and keep listening what they need.

Probably to expend more products lines once we got more resources.

Cheers and happy new year.

A good place to read about and get in contact with windsurfers using GPS is http://www.seabreeze.com.au/forums/Windsurfing/Gps/

The organisation that approves GPS devices for speed measurements and records is GPS Speedsurfing http://www.gps-speedsurfing.com/default.aspx

A good device to look at is Locosys Genie GT 31 http://www.locosystech.com/product.php?zln=en&id=30. This is the most commonly used device for measuring speed for windsurfers. 

This guy has developed a custom firmware specialised on windsurfing for the device http://mtbest.net/setting-up-navi-GT31.htm where I am sure you can draw some conclusions on required features and algoritms etc.

hi folks,

i am all in! i have been using gh 615 with the latest gh 625 firmware for years now. i bought it when i got into kitesurfing course races. check out this thread i started more than a year ago:
http://www.usglobalsat.com/forum/index.php?topic=932.0

right now i use it to record data of course and i analyse later on the computer. if you set some waypoints right you can also, with some practice, estimate your upwind performance.

Hi,

It is nice!
I have read throughout Tom's paper and bought GT-31! I have not ever tried it. Do you have this kind experience? And is it feasible to ask him to cooperate with us?

Sincerely,

Geoffrey

Hi Holden,

Nice to see you again! Our marketing would like to implement this kind application into our model to provide more wide services.
Do you mean VMG? It is no problem for us and we are checking the way to improve speed through Doppler and Tom's function.


Sincerely,

Geoffrey

Hi Geoffrey,

I have not used the GT-31 or know Tom, only read about the device when looking for the best device to use when sailing and windsurfing. I have been using a Garmin eTrex Vista HTC for a long time but is looking for something more convenient and accurate (my GPS does not use doppler). Found the GT-31 but would prefer a wrist mounted device as easier to read at a glance.

I am sure Tom would be interested to talk to you. I do not know him at all but from reading his website, it looks like he is doing the development as a hobby. Probably best that you send him an email and include a link to this thread so he can see the background. Hopefully his algorithms should not be too hard to port to your device. 

Regards,

Andreas

Hi Andreas,

Thanks for suggestions.
I am wondering how did Garmin eTrex perform in this application? Is it good enough?
I will try to contact Tom, hopefully he is not employee in Locosys. ;)

Hi Geoffrey,

The etrex works but is not great for speed reading as speed fluctuates a bit as not using doppler. Also not convenient to have dangling from your neck which actually disturbs the speed readings in low speed as not fixed in space, a watch formfactor would be much more convenient. Very good to have sea charts in the etrex though which is great for sailing.

If you do develop a firmware for sailing and windsurfing, you should definitely include a sailing countdown timer. Not sure if you have this already but features should include:
1. Easy to set countdown with starting periods with minutes increments up to 60 minutes.
2. Easy to reset countdown (i.e. press a button once countdown has started and countdown goes to closest full minute (i.e. goes to 3.00 if you press the button both at 2.55 or at 3.05), essential to be able to reset countdown if you miss the first start signal by a few seconds).
3. Beeps at each second the last 10 seconds of each minute the last 5 minutes with stronger beep at full minute. (beep, beep, beep, beep, beep, beep, beep, beep, beep, BEEP). BEEP at each minute for 10 to 5 minutes before start.
4. Once countdown reaches zero, normal stop watch should automatically start taking time so you can time the race.

Hi Andreas,

Thanks for suggestions, it seems not difficult to implement. I will check engineer.
I would like to know does BEEP start when countdown timer was getting start or normal timer was getting start?

Hi Geoffrey,

I am referring to a LOUD BEEP at the each full minute (10.00, 9.00, 8.00...1.00, 0.00) during countdown.
As countdown timer reaches 0.00, there should be a loud BEEP and normal timer should start to run automatically to make it easy to time the race.
There should be slightly less loud beeps at the last 10 seconds before the countdown timer reaches 5.00, 4.00 ... 0.00 (not necessary with the less loud beeps the 10 seconds before each full minute when more than 5 minutes to start). 

Hope I am clear!  :)

We will make beta firmware for testing.

I did test a GT11 (old version without SirfIII GPS).
When you got a good fix and clear sky, the speed information what D*&Y$$ good (due to doppler calculation).
Unfortunatly, the bike mount was too weak and the device weighted a bit.
By this time I was testing on raod biking. I made a few runs OK, but on bum it fell down and get broken.
One drawback for me as user is the joystick for navigate in the menu.
I fell more confortable with side button like GH625.

Dear customer,


Thanks for information providing.
But I heard many people interest top button. ;)
Any further updated?
