You will need to run the light all the time, that way they done see you. If im calling grey fox then the grey fox pup in destress is hard to beat. But you wont get many reds to come in to it. If im calling coyotes and red or grey fox then I set up at night just like I would during the day, run the light the hole time. I will use hand calls alot and rabit or bird destress sounds if im calling for coyotes and red and grey foxs. Seems like the grey fox pup tape will bring in greys most of the time but as the season goes on you will need to start mixing it up some because of calling pressure.
I like to set up in field that have clear cuts and hard woods around them. I will set up to where I can cover all the field with the light. Just keep the light above there eyes just so you can see there eyes. Dont shine dead in there eyes. Keep them in the halo till your ready for the shot.
I hunt some in the woods at night but most of the time I try to hunt fields or growed up fields when I can. Old roads, old home places, cut crop fields, growed up fields, strip mines, all make good set ups at night. As for calls the cottontail, yellowhammer woodpecker, rodent, destress calls work well and I have better luck with high piched hand calls at night. I run the call at night just like I do during the day, start out with med volume and get louder as you call. If im useing the grey fox pup tape I let it run all the time, if its a cottontail or something, I will very the volume some. Hand calls I use in sets I will call for a while then stop and wait, then start calling again. But everone does things diffrent just find what works well for you and go for it.
If they hang up out of gun range then try to lip sqweek them in, this will work alot of the time or even switch calls will do it sometimes. Hope this helps.
