Digital trail cam
Snoogsdad makes some good points , but when you're talking about a digital that you're only really using to see what's out there , not opening an exhibit at an art gallery , then how sharp do the pics need to be ? You aren't wasting film , so isn't 50% of 54-108 frames adequate ?
Yeah , I'd rather take nicer pics , but for general scouting almost any trail cam will do , and the one in the link above is very affordable .
