Yes, but they advertise compatibility with the Mychron beacon.  Maybe they should say "Once in a blue moon you will get lucky and actually get lap times while relying on a Mychron beacon."  The other puzzling thing is that others at the track are using the XT's and I haven't heard them say anything about it, though I will ask them next time out.

LOL....mayeb it will work out  ;D maybe it was the weather ;D

Um, I feel left out...

I haven't heard of XT.  They have a website for their product?

I have most of the info on the site at www.sportbikemadnessracing.com

look at my site...and go to the store and lap timers and you will see... www.2centsracing.com

You could also try www.xtracing.com if you are just looking for info :).

 :P our shop is closed for renovations in north western NJ.  ;D

The Ultra Lap works fine with the MyChron IF, I say IF, you put an external 12V battery on the transmitter and switch it to the 60' scale. Also should be on a tripod or fairly level with the sensor on your bike. Ultra is sensitive to placement, but works fine with the MyChron transmitter if it is set up as above..
