Mine is a PACT Mark IV. I chose it because it works as both a shot timer and chronograph. It's about 5 years old. I used it mostly as a timer at first. Now I'm using it mostly as a chrono.
The timer function has a lot of versatility. If you can think up a scenario for a timer, the Mark IV will do it.
Chrono function is pretty straight forward. Gives individual shot velocities, means, SD, MAD. Also has a rudimentary ballistics calculator; plug in a velocity and bullet weight and it generates some numbers. Not great because it assumes a generic BC. I have not used that function.
Two things I don't like about it are:
1. No auto shut off. Not a big deal, I only drained one battery early on. Now I carry a spare battery, but have not needed it. Guess I learned my lesson.
2. There is no printer currently available. I bought this after the printer had gone out of production. Haven't looked too hard for one and writing down the data in a notebook helps keep me organized. What I'd really like is a chrono that hooks up to my lap top.
I showed you mine. You show me yours.
