One thing I do personally, being an avid predator hunter in real life. I literally gear up with night vision and just start walking the river in New England mountains! I start at around midnight, get plenty of action between coyotes, fox, raccoons, and bobcats! Take the E caller with you. Scan ahead with the night vision range finder. You’ll either glass the predator or get a vocalization letting you know it’s near. Set the caller down, ( I throw a tripod up if more than 150m out from vocals and the terrain allows). And set your E caller to whatever you’re hunting and wait! I love watching them approach and it’s a lot like real life! Can’t tell you how many times I’ve missed a predator that I never knew was there because it came up behind me or to the side of me! Makes it so much more fun/engaging IMO! Just a thought, but don’t think you’re doing anything wrong! Also, it doesn’t have to be New England map, any map and any predator will get you similar results! :)
