    IT SEEMS TO WORK GOOD. I HAVE ONLY MOUNTED AND ZEROED IT SO FAR! This is my first thermal scope and was pretty easy to figure out all of the menu&#039;s however it would be nice if it came with a manual explaining all functions,warranty, etc. I was worried about the little rubber power outlet cover getting pulled off and lost so i added a velcro dot to the top of the cap and underside of scope to keep it from dangling. Hopefully this will keep it from getting torn off when using remote battery pack. I chose this unit because of the five yr. warranty and good reviews. However i think the trijicon turrets may have been easier to work in the dark than trying to feel for flat buttons.Just takes a few seconds to feel if you are on the right button or not! The free battery pack and shuttered eye piece Todd thru in was definitely a plus. Over all i am pleased with the unit! And Todd was very informative and a pleasure to work with! I would buy from them again! THANKS ULTIMATE NIGHT VISION!!!

    The halo lr was great! Ordering was easy, along with directions of how to receive/return the device. Scope was super simple to set up and a dream to view through. Only down fall I had was the first set of batteries only lasted 45 minutes after those were out the next set lasted the rest of the time. Would/Will rent from ultimate night vision again!

    Just Amazing

    If you are looking to hunt coyotes or pigs then the HALO LR is the answer. The guys at Ultimate Night Vision are very helpful and they use this unit every weekend. HALO LR is good close as 25 yards and i feel okay taking shots past 300 yards.
