I answered NO, it's something that aids in scouting but by no means are you guaranteed a shot at any animal you catch on camera. I used mine a couple years and got pictures of bucks I never saw. It didn't help me one bit except get a picture of a buck I would have never seen otherwise.
I didn't put it out this year. For most people it's just another fun item to use.
I suppose if you put out multiple ones as well as the video ones like the Drury's then yes, it cuts out the leg work and saves time otherwise spent glassing and watching...but it's also work using the trail cameras....it's a catch 22..
