I have recently gotten one of the new Night Eyes headlamps to try out and to say I am impressed would be a bit of an understatement. This Predator hunting scanning light is a very light weight headlamp made from high quality aircraft grade aluminum, one extremely bright CREE LED light puts out enough light to see a predator or treed "one's eyes at hundreds of yards. The Night Eyes headlamp/scanning light has a very long runtime with 3.5 hours on high and 8.5 on medium, using the included rechargeable Lithium-Ion batteries. (An extra battery is included)One of the coolest features I have found on the Night Eyes Headlamp is that you can set the lower power to whatever you want, simply hold the switch in and release it when you reach the desired level. This Scanning light is perfect for predator hunting or general use. I have been using it for everything, but mostly when I am running my hounds. I had switched all of my Garmin tracking collars to the LCS Reflective Day-Glo collar strapsand I have been blown away by how far this light will make my collars shine, it is well over 300 yards. Another nice feature is the included "alo? which goes over the front of the light to keep the bean tighter. I prefer the red light as it really cuts down on the swarm of insects that a white lights draw on a warm summer night. I did get a chance to use this light coon hunting and the included head strap is the most comfortable I have worn, the extremely small battery pack on the back of the strap feels as if there is nothing there. We didn't get to see eyes on this trip but I am sure it will be no problem as it lit the tree well. That has been a complaint of mine in the past as most headlamps with this kind of performance usually have a huge battery pack on the back of the strap. I can't wait to use this for predator hunting!
