In my experience the Deer Cam DC-100 was the best. I have the DC 100, had a DC-200 and i have a Moultrie 4.1. The DC-200 never took a picture, i sent it in 3 times and they told me it was fine each time i just never took a picture. Ive taken more than 200 with my DC-100 and all the deer were perfectly centered. The moutlrie is good and has amazing quality pics but a slow reaction time, so you have to put it on a feeder or something like that.
There can be too much of a good thing with antler rattling.
I like to hit the horns together for a good 30- to 40-second rattling sequence and then hang them up and resist the urge to hit them again.
This works to the hunter's advantage, because if a buck has heard it, he may have been 300 or 400 yards away and he comes in and he's not exactly sure where it came from.
When finally is time to rattle again throw a slight change-up into the routine.
The second time, don't rattle as loud...
