The more it have the easier it is to monitor, just be selective when you check the cams to avoid bumping any residing deer out or alarm them with your scent. I usually check my cams once a month pre season and to and from the stand during season when possible. It's hard to do tho, I have a few on field edges is can get more frequently, but I try to stick to the once a month.
We have 25 running right now on two 500 acre chunks of land 15 on one and 10 on the other. Would like to get about 25+ more. There is no such thing as to many! When you run out of trees get stic n pics! Sent from my arrow using Mathews!
