The problem with beepers is that they bleep all the time, which is very annoying, particularly when waiting at traffic lights with the hood-off.
The joy of the Audicater is can be programmed with a delay before bleeping, and the volume of the bleeping can be also be programmed to get louder. A touch on the brakes resets everything for the traffic-light situation.
I have had one on my +8 since '07, Excellent bit of kit.
