The AMB/MYLAPS also miss laps on occasion .No system is perfect.It comes down to money for some thing that just counts laps.Both system are accurate.We use the I-LAP IF system and sun does not cause a problem.
Like i said it comes down to money.The IF systems are becoming more and more popular.Will they over take AMB as the standard ,most likely not just because AMB has over a 20+ year head start in the lap counting business.Just think what this conversation would be like if the IF system such a I-LAP had the 20+ year head start and the AMB/MYLAPS was the new kid on the block.Then what would people be saying!
