I copied a reply I made in another thread:
for more info.
From that site, I gleaned this:
The mylaps system is used in Barbados for cycling, karting and circuit racing it seems. I don't know if its only one or there are more systems, but again a cost saving measure for the JRDC could be to sell the idea to other sports here in Jamaica as well.
The JRDC already has a working relationship with the Jamaica Cycling Federation, and as such the cost for acquiring transponders could be shared with them as well as karting. The JRDC so far only uses the transponders 4 times a year, so if they are used for rallying, sprints, karting, dexterities, cycling etc, you get the picture, the cost can be borne by a greater cross section of clubs and associations and thus be made more affordable to each.
I think this goes well with the OneSport concept being brought to the sport by the chairpersons of the DRC and the JRDC.
Add to this, a browse through the list of countries that employ this system will reveal that it is indeed a widely used and popular system that can completely fulfill all the timing needs that we have here in Jamaica.
When purchasing equipment, I learned from my dad very early not to use exotic, experimental or unique items.
Use what most people in similar circumstances use.
Reason: parts are available more readily, repair and service, advice etc.
