I am curious if there have been any improvements in durability of the LR or any updates to either unit? I am considering a Chronograph purchase but really dont know which direction to go. My concern with the MS is I need to use it on several short barrel guns where no barrel extends beyond the handguard. How would you then attach it? Simiarly I have concerns about the LR when shooting braked guns and suppressed guns and getting reliable results without the muzzle blast blowing the devise over or simply blasting it.
You put a braked muzzle 3-6 inches in front of the LabRadar. Blast doesn't really touch the unit. Unbraked muzzles are set even with the front of the unit.
While a software update came out a couple of months ago to allow control through a Bluetooth/phone interface, I doubt there have been any internal changes to the Labradar.
I read Frank's report of how easily his Labradar was damaged. That does raise some flags for people who need a "field-ready" device that could get banged around some, but my unit sits on the bench or on the ground next to me; it stays in its case if there's high wind or anything else that could tip it over.
I think I posted somewhere in this thread, certainly in other threads, that there is definitely a learning curve to using a Labradar. Frankly, if you need something that works primarily on indoor, short, or cluttered ranges, you had best try one out in your environment before buying one. The vast majority of the time I use mine, it's on a wide flat firing line where it's 100 yards to the nearest berm. I have no problem getting consistent readings (that is, the unit is triggered by the discharge,"sees" the bullet, and reports/records velocity). Late last week, I used it on a different range where there was a 50-yard berm just a few feet to the left of bullet path to my 100-yard target. Apparently the 50-yard berm being that close to the bullet path and radar beam caused some interference as I had a few rounds that didn't trigger/track. I moved to a bench 15 feet to my right, putting the 50-yard berm well away from bullet/beam path, and every single round triggered and tracked. Like I said, there's a learning curve.
I can't speak to MS quirks because I've never owned one. The instructor in a class I took used one and it's safe to say the MS has quirks of its own.
Hope this helps.
