"I turned my light on and there stood a coyote after almost 4 years of trying to get one and getting closer every year, I was now this close. I couldn't get my light on it right with the scope and didn't have a shotgun."
First question: Did you have your light on scanning the entire time and couldn't get the shoot light on in time? I was a little confused . Always have the light on and be scanning if you weren't.
Those coyotes may not be there a few days from now, so I would stay on them. I always try to mimic their vocals as much as possible. BE PATIENT and don't over call to them. If they are there, they will know where you are. Most dogs will come in silent after circling and checking the wind. Don't be afraid to leave your shoot light turned on . I will often scan with mine if I think something is near by.
JMO I would repeat what worked the first time.....
Always remember, with coyotes, less is more. Don't be afraid to sit silent for 10-15 minutes at a time. Always try to be down wind of the call if possible. I like to have a shooter at least 100 yards down wind of my call.
What sounds were you using? Distress , coyote vocals, etc? I had good luck with yip howels this time of year. Nothing to challenging to scare off other dogs, but lets them know another yote is in the area. Think about what they are sounding off with and fire it right back at them.
