Not me. They are a critical part of my QDM management plan. Mine are not cell, they are 900mhz wireless with solar that run 24/7/365. I've been running this camera network over 10 years and it transmits full resolution pictures back to camp where they are stored on a local computer. Once every week or two, I copy them to my laptop for review and entry into my database. They let me trend the herd year to year. They allow me to evaluate the impact of habitat decisions including timber management as to how they impact the herd.
I find them almost zero help in hunting, especially mature deer. They are of some help when I want to take a kid out. I can tell which box blinds have had deer feeding nearby during shooting hours in the last week or so than others. They are still no guarantee, but they increase the chances the kid will see something. My mature deer show up mostly at night and they really don't demonstrate any real pattern. I don't even look at them for stand selection.
We have a log were hunters are required to log each hunt along with observations along with their stand location. We do this for both safety as well as another source of data for QDM analysis. If someone goes out to hunt and does not come back, we know where to look for them. At any rate, knowing the location where others have hunted recently and the trails that are commonly used to get to those locations, it is easy for me to eliminate locations that have had a lot of recent pressure. I find this more productive in stand selection than looking at camera data.
I don't think cell cams are any hunting advantage at all. First, almost all of them only transmit decimated thumbnail pics which are not high enough resolution for analysis purposes. So to do any QDM type analysis, you need to go retrieve SD cards. It is not like they are going to provide any actionable information for hunting. What are you going to do? Get a picture in your stand that there was a deer 5 minutes ago at some other spot on the property and move to that spot? That is just not effective. Knowing deer have been at certain location on your property in the last week without having to check SD cards is the most advantage they can really provide for hunting. I think the best use of them is for folks who live far from their hunting property to get a feel for what deer are using the property.
I think the biggest hunting advantage of game cameras in general is "Building Confidence". Just knowing that mature bucks exist in your area and do use your property give folks the confidence to sit in the stand just a bit more knowing that the big one "could" appear at any time.
