If you don't have one you need to buy the 15.00 Thermocell Holster..you can get it from the Walmart online store with 96 cents shipping
I have a Summit Backpacker..Teh holster has a built in adjustable strap with it.I strap mine to the front bar..WOrks like a charm.
While turkey hunting..I just lay it on the ground in front of me.It's supposed to have 15 foot protectection...not sure about that but it works up close..
If the lone wolf looks like I think it does..I'd make a bracket that you could screw into the tree..one that would keep the unit laying down flat.
