I have deployed my first order of Nite Guard units and ordered six more. I want to thank you for an absolutely outstanding product.
I was initially doubtful as to the effectiveness of your product, but nevertheless placed them about the approximately 20 acre pasture that I use for the saddle horses. Each Nite Guard unit was placed such that its beam interlocked with the beams of each other unit on its flanks, creating a solid wall of visual coverage around the entire perimeter of the pasture. Thus, any predator approaching could not avoid seeing the blinking red light, no matter the direction he came. Given the long identification range of the Nite Guard, this ensured predator coverage on the entire pasture with only four Nite Guard units. I also supplemented the electronic units with three-foot long strips of your reflective tape for day-time protection.
I set up the units in the morning, including the tape. That afternoon not a coyote, bobcat, or wolf sign could be found, and the dogs did not find scent. That night the entire area was absolutely quiet; no yapping, screaming or howling.
It has been three weeks since the Nite Guard deployment and not a single predator of any kind to be found. I am amazed and very grateful. Coyotes and wolves have been attacking the cattle herd and the home corrals for years, but not now.
Prior to buying your Nite Guard device I had struggled for years with the predator problem. Fifty years ago I could have poisoned or shot them out, but not in today's world. Your device has worked, absolutely.
