We have been racing micros in my store for several years. I started out using a lazer based system. I was OK but did not work with the off-road buggies & trucks due to their increased verticle movement. I found the Trackmate RC20 IR system and purchased that. I used it for a couple years. It was a big improvement over the lazer system, but only had 14 codes available and reprogramming a transponder was a time consuming, hit or miss, proposition.
I was VERY pleased to find Craig (I-Lap). Not only is he much closer (Chicago area vs. western Canada for Trakmate). But his knowledge & customer service is un-matched!
We run with Alycat software, and the 2 go very well together. I-lap transponders have a stronger signal than the Trakmate, and will actually pass through some paint jobs! I don't recomend that however. Missed laps are few, and usually ascociated with either a transponder getting moved out of place, or something else moving in the way of the transponders' emitter. Care in the placement of the transponder prevents any missed laps.
We have had many instances of cars tumbleing under the bridge without losing the lap!
All that for less than I spent on the original lazer system! I wish I had found Craig sooner..
