Shooting with a buddy awhile back I was reviewing data on my old shooting chrony and he wanted to know what "hack" I had done in order to make it give high, low, average, ES, SD and review all the shots.
He was kind of upset that is was just a plug and momentary push button away, all the years he has had his.
In his defense they didn't always have the information in the manual, if he would have read it anyway.

Lots of other stuff it will do too but that's all I use.
