What are the advantages of cell cams for the average hunter, and maybe most importantly outfitters, in the Midwest?
Once installed along known travel corridors, bedding areas, and food plots, they allow near real time monitoring of deer. They also provide volumes of information about areas with the absolute minimum level of human scouting (and residual scent). With external batteries and solar chargers, they can essentially be left in place indefinitely.
Deer are creatures of habit in the Midwest, and established trails are used by generations of deer so long as the surrounding habitat remains constant. Food plot installation, transitions from row crop to CRP, and other changes to the surroundings can certainly create new travel patterns, but in general, deer often default to the path of least resistance IME. The rut is the obvious exception to this.
If a big buck is bedding on the neighbors, and traveling to your property to feed, you can essentially monitor these "fence crossings" and potentially get set up before he arrived at the "X". This dramatically increases efficiency for outfitters as they manage multiple properties and bucks for clients. During the pre rut and late season, this strategy can be used with devastating affects as the deer can be very predictable during these times of the year.
My vote is to ban cell cams during the hunting seasons on public and private, similar to supplemental bait and mineral sites (in Iowa at least where baiting is still illegal). I'm fine with guys using non-trasmitting cams during the season, as they are accepting the risk of spooking deer every time they go in to swap SD cards.
