I use an old Nikon Coolpix 880 with a whopping 3.3 mpxl
It does great, but the batts are 11 bucks apiece. Got to get one that uses AA,s.
My fever is up for this spot. I was getting a lot of deep bouncy signals with the 4x6 (7-8 inches). This merc was at 6". Not very trashy . I'm taking the 1400 next time
