So, here's the new question: With the Garmin unit running $600 and a ton of used LabRadars on Ebay for ~$300, what's the call there?
I'm sort of amused by the velocity distance curve, but I'm not sure if I'd actually use it or not.
Obviously, if the new LabRadar product gives that functionality then it's the best of the three.
Good question. For me, I could have bought a LabRadar whenever I wanted. It wasn't the cost that stopped me. It was the size and that it would be unwieldy at an indoor range, which is where I shoot 100% of the time. For me and my usage, I wouldn't use the current LabRadar if I was given one for free.
As far as the functionality at different distances, it's amusing but I have had that for years by using the ShootersCalculator.com ballistic trajectory calculator here. Certainly atmospheric conditions will affect the velocity somewhat, but those conditions are transitory, so the numbers you get today won't hold true tomorrow or whenever you're out hunting, if that's what you use that info for.
If/when LabRadar comes out with their Garmin copy, it'll end up being a "beauty contest" to choose which you want. I've got the Garmin and it meets 100% of my needs.
