If you have your camera over a baitpile and are worried about the batteries lasting, try moving the delay on the board higher so it doesn't take as many pics so fast.

On a bait pile you shouldn't have to worry about missing anything, and taking a picture every 10 seconds to one minute will result in hundreds of picture of the same thing.

I have noticed on my mineral piles, i have to almost set my delay for 5 minutes or i will get too many pictures.

Oh... and another thing......the obsession has begun.
