I recently took possession of a ATN Mars ltv 640x480 4-12 thermal scope which through Peter at ATN I acquired at a superb discounted rate but only if I rated it .After bore scoping the first shot was approx 4inch out and soon rectified on the one shot zero I did use more than one shot as I tested it and fine tuned it out to longer ranges .After recently taking on alot of forestry areas I found my usual NV set up being plagued with white outs with the amount of brash mats etc on the clearfell and restock areas so on my maiden voyage with the scope ( it's mounted on a .270 ) I managed to quickly find and identify my target and account for 2 deer at approx 180yds on a misty night with little wind since then I've been out and shot out to 277yds and think the scope is an easy no frills unit ie turn it on and shoot which suits me and like the stepped magnification ie 4x base for quick target acquisition and then step up depending on distance - I've set it on black hot which seems to suit the unit and like the simplistic method of brightness control etc ie simple tap on one the 4 buttons the units battery system is excellent as a fully charged internal battery after several hours use has hardly used any power and at 650gr the unit is very light which assists with speed of getting onto sticks etc - the only mod I've made it to put a coaster on to the front focus ring but not because it's stiff it's just easier to use in the pitch black I'm fairly old school and don't understand ( or want to ) all the jargon from reviewers on pixels - sensor measurements etc I just want a scope to turn on - quickly identify your target and shoot out to reasonable distances and I've found this scope fits the bill for me as more than capable work tool ( although it's got a recorded facility I haven't used it as yet ) my only criticism of the unit is that it would benefit from a front lens cover as I found the other day when snowing I was having to clear the lens but as a lightweight capable simple unit I'm more than happy with it and at way under 50% of the price of the new must have thermal scopes I'd recommend to others
