This product is/was not what I was really looking for as a coach.  It is nice but the TYR a step lower does more for my needs than the bells and whistles that accompany this model.  I am going to try and return it for another watvh.

I should have fully read the review another customer had posted before I bought.  This watch takes multiple splits every time you hit the split button.  Swimoutlet custormer service has been great and accepted the return.  TYR on the other hand does not seem to care that they have a poor product on the market.  Stick with the z-100 watches and avoid the z-500 model.  The extra features are not worth a watch that does not do the most basic funtion accurately.

this is a great stop watch for coaches or trainers alike that has an integrated workout routine.
At 1st I thought it was a slight malfunction on my watch but after using other z-500 this watch has trouble doing single split times. Every time you hit the split button it will split 3time or more depending on the quickness of your hit.
its pretty much an unnecessary watch, i would much prefer sticking with the z-100 or other stopwatches
