I know I seen on another post once that a guy had went to Radio Shack and bought a lager haldheld viewer to plug into his LR for a larger viewing screen (2.5") and I'm pretty sure it costs around $50 or $60. Of course, IF you alredady have a Digital camera that takes CF cards then you can use that with excellent results. I generally take along my Nikon Coolpix so I can zoom and pan the images while in the field. As a matter of fact, I often times will collect the CF cards in my cams on the way to my stand and then review the pics during any slowtime!
