There are several videos on YouTube you may want to watch concerning how to use it. It should also come with a CD from WCS explaining the basics I think (it's been a bit since I've bought one). Remember that this device is a bite-pull trigger, so what you use as bait may make a difference. WCS recommends CCB from Proline Lures and I've used it with success. For the Collarum itself, I prefer the T bite trigger over the tube bite trigger. To install the T you'll need to make a notch in it at the bottom and then drill/cut holes in the side so you can run a piece of wire through it to keep it on the device. I also like to wrap the T with gauze or athletic tap to give the CCB something to "cling" to. Set location does matter with the device as you need to make sure the coyote can only approach it from the front. Also, determine how many coon you may have issues with as they can set it off without getting caught. If you have a lot of coon, I'd recommend also setting cage traps or DPs for the coon around the property to help limit the changes they will get to the Collarum. This device isn't a guarantee and many have low success with it. My last time using it on a job it took 4 days before a catch and if I remember right I had at least three if not four of them out.
