you can find them in any sporting type stores hunting/fishing or in their catalogs - my brother-in-law has been using them for years to check out trails for activity before he sets up his stand -- one year he made the mistake of mentioning at a holiday family get together that he had it set up on a trail in the woods out back - haha i couldnt wait to sneak off for an after dinner walk -- his camera is older and has film in it that he takes to get developed, needless to say when he picked it up along with some turkeys, deer and a coyote pics he had captured a full moon rising!
