I've been using the Pocket Pro II for a few years and have been happy with it. I find it very easy to change the settings say from delayed start (working alone) or instant start (working as an RO). I like being able to easily scroll through the shots fired to check times between shots or target transition. It easily clips on to an empty mag pouch or pocket. The screen is easy to read even for my aging eyes. And I love that it knows I will never remember to turn it off so it does it for me to save the battery.
