I've used a Prochrono for a few years now, and recently have started experimenting with a Labradar, perhaps 3 - 400 rounds or so. I'm finding the Labradar to be more convenient to use at our local range, which is crowded, has limited protection from the elements, etc. The Labradar also produces conveniently formatted data, which I find helpful.
I consider it to be pricey and had to wait a month or so for the unit to arrive as it was back ordered. Smallest projectiles I've used have been .277. I've had read outs on all shots fired (not so with my Prochrono) but the unit has not reliably tracked .277 boat tail bullets to 100 m. No such issue with .308 projectiles and larger.
