Went to the range today with my new Labradar. Works pretty good once you get the settings right. Mine was picking up the bench next to me. I had to adjust the sensitivity. I was shooting 6.5x47 Lapua and he was shooing 308. I adjusted the level to 6 and it was OK. When I changed to 22 hornet and had to adjust the level to be more sensitive at 4, and he was shooting the 308, it picked up his shots because of the sensitivity. Works best with no one around. It also chews through batteries. I went through six in 2 hours. Need to get a USB battery pack. Batteries need to be strong for it to work good. At half battery level it would not work at all. Is it worth the money? Jury is still out.
