For tracks looking for a lap counter there are alternative's.The I-LAP is the best alternative to a AMB,even over the Robotronics.
I have been running the I-LAP going on three season and it has worked flawless!yes the AMB is used at large events,but who care's.Most racing is club racing and i am willing to bet less than 10% of rc racers will ever attend a big national event.
All these systems do is count laps ,and both do a great job of that.
I-LAP PT'S are around $40 ,which helps keep the cost down.For those track owners who maybe interested in the i-lap system don't let the racers talk you into a AMB if you can't afford it,it is not worth putting yourself in debt for it!for those who will complain about it not being a AMB they will come around once they see it work.Just offer a track set of transponders,that way the racer who does not want to put out for a PT can race without the extra expense.Also the one's who complain about it not being a AMB don't have to put out extra for a PT and leaves them no excuse for not racing at your track.
The I-LAP system is used at many tracks here in the U.S and there are many tracks in Europe using it as well.They are sold all over the world and gaining popularity because people are getting tired of the over priced AMB.
Die hard racers will race no matter what type of lap counter is being used!!Just think they could always go back to hand counting!!
For the racer who say's he will not race at a track were AMB is not used .your not a racer just some who looks for excuses not to race,and a lap counter is not a good excuse!
Lets face people will complain about the cost of the AMB systems $3500+ new and they will complain about the cost of the transponder $90+,but most of you will still buy because you think you need it and that is what AMB/MYLAPS is counting on.
