I've run the gamut with chronographs. I bought a LabRadar when they arrived on the scene. In my opinion, LabRadar sat on their laurels. They had a great concept but failed to deal with the unit's problems. It drove me nuts with missed shots and a lousy phone app. Yes, it does provide down range velocities, but that's really just a novelty. I sold mine at a loss when I bought a Garmin. The difference is light night and day. About the only good thing I can say about LabRadar is that it's big, orange and hard to lose. The Garmin is small enough that I can misplace it without much effort.
OP, I suggest you spend the money for a Garmin. Or take a look at LabRadar's LX model. I can't vouch for the LX, but it looks to be a Garmin competitor. One hopes that LabRadar learned their lessons with their original design. I still have a bad taste in my mouth over their first unit, so I'd be wary that they didn't really learn much.
