I know, for sure, my concealment gear hides me from a coyotes vision (at least in the area I'm thinking about). As long as you hold still that is.
I was returning back to my sit this deer season after taking a piss about 25yds back from my sit (to make sure it's not in the wind flow by that Gulch), when I saw one bopping along down the trail my sit faces towards on the other side of the Gulch. Entering at 3 o'clock and proceeding up to about 10 o'clock where the trail line he was on reconnects after the opening I'm facing where two meadows criss-cross. I was in motion when I first noticed him, he hadn't seen me yet, so I held still while standing... a moment after that he had turned his head towards my direction with a brief pause, but it was a split-second after I had seen him first and become motionless with the leafy suit on. In the blink of an eye he was carrying back on about his merry way. No change to his chugging-along pace nor demeanor.
There was another time as well that same yote came in running more towards my direction, (I wasn't calling so figure something on the private property must have spooked him like their dog) he was like coming in from 12 o'clock and veering towards 7 o'clock off after crossing the gulch in front of me, into the direction that other criss-cross meadow flows into. For Shits and Giggles I tried using my coaxer call to see if I could get him to come back this way, but no dice on that one. He was running at a good clip when he stormed thru. There's no way he'd have run that direction if he knew I was there. And generally speaking the wind comes from like 9 o'clock and flows over to 3 o'clock at that spot, which is what works about it. And long story shorter, I can't have Does feeding at 25yds from me for long periods of time sitting in my Larger size Helinox style chair (at this same place the yote ran thru, and the same place the Bobcat sauntered thru) if that natural blind material that covers to about my knees, and the Leafy gear weren't working.
SIGH... it's gonna be a WHILE before I can do mouth calls again though
My lungs are soo raw right now. I called into the Dr's office today pleading for help, she called in a Script for Prednisone and an Albuterol inhaler, so we can try to calm down what I'm sure is a buncha inflammation I got going on down in there from all this coughing to try to kick up the chunks of lung-butter hangin' around down in there. Man, all this coughing really really takes it out of ya. This is no joke. Anyone reading this, remember to be very thankful for being able to breathe without problems man. We take that for granted big time.
