Let the Buyer beware.
Excellent piece of kit as you would expect from CHRONY. I bought it to replace my ageing F1. What I didn't expect however, was that (unlike my original F1) it only displays one function i.e. 'Speed'. The other functions (average speed, ES, SD etc.) can only be obtained by purchasing the printer. That, and the fact that if I wanted to 'upgrade' I would have to send it back to the CHRONY company and pay more money, is why I couldn't recommend it to other shooting buddies.
