I've had an Oehler 35p for about 15 years. It's been a great unit. If I hadn't won this one in an IPSC shoot, I probably would've bought a Chrony. They seem like a good piece of equipment for the price. I don't have any experience with the Pact chronograph, but their timers, and scales have always worked well for me, and their warrantee can't be beat.
