Ralph, here is what I have. Been thinking of upgrading to a more expensive model that uses the same batteries as my Thermal scope and might consider selling this. It has worked great and is a Thermal monocular...I caught it on sale last year and used it the whole night season...bought extra batteries/packs. It generally lasted 6 hours+ on a set of batteries...just pop another battery pack in and keep hunting...recharge them and use them the next night. No issues whatsoever with this unit.
It may be more expensive than you are wanting to go.
