[MadKaw]

I'm after a Bluetoothe gps Receiver for the race chrono lap timer.

Anyone know much about them and will this do the job..?

Dunno about that Dave , but have seen mobile phones with GPS used as timers . Free software from from memory "racecrono" or some such . They had a lot of aussie tracks listed on their site .

I can't see what the update rate is in the specs, mine is 5Hz, and I know they are using up to 10Hz now also. This governs the accuracy as it updates the position more frequently.

I'm using a Qstar GPS nano like this one

Looking at specs I'd say its a 1hz so slower updates, but its much cheaper..

What would the accuracy difference between 1 hz and 5hz..? ie, a second or less.?

[Blurr]

from what i have learnt over the last couple of weeks online and talking to a few nerds e.g. Dave#3 and my IT guys at work is this

5Hz = equals 5 position refreshes perr second therefore more acuaracy ove the 1Hz that obviously one does it once.

I know when I used Watties that it played up a little if it couldnt see more than 10 satalites.

Dave I am using one of these:

Bought from a phone cover stall in Castle Towers for $115
In one session at the Creek it picked up 16 satelites

I have paired it with a N95 & have never been let down, unlike a dude I was trying to help at the creek recently, he had a cheaper smaller one & it would not work even though it had a wireless connection & was reading on the phone

Have you checked out the list of compatible phonnes on Race Chrono Dave?

I have these and they're quite good!

these work perfect..mine picks up from the centre console in my car and has worked perfect for 2 trackdays so far. They are solar assisited so last 20 hours or so and take a nokia battery which is sourced easily if needed. Also has a magnetic base if required.

This is the cheapest your going to get a good one..

hey, I just exported a lap to google earth from racechrono, check it out. You can also export at a excel spreadsheet, but haven't worked that shit out yet..have to delve a bit further into google earth to work out how to read more into the lap..

You'll go faster if you stay on the black stuff between 1 and 2 and also 7 and 8
