Now that is one feature I would really like.
I also like the idea of one button, my old... crap... I can't even remember the name of it. Someting tournament Pro something or other, made by Bottom Line.
Anyways it had one button, push to turn on unit, push again to go through options, turn dial to option, push to highlight option, so on....
Real easy to operate.
Another option I like is the "real time" display. Sure a flasher might be quicker but do you really need to have mili seconds? A 1/2 or 1 second delay is not bad.
