What does the terrain look like? Pastures, Open Fields, Hay Meadows, Wooded?
Its fine to use a powerful spotlight to illuminate the Yote when its time to shoot, but I use a much less powerful light (Red LED) to 'scan' with. You aren't (or shouldn't be) looking for the whole animal when 'scanning', just the shine of their eyes...which can be seen from a long way.
Read all you can about calling/hunting Coyotes, there is a lot to know. You need to know how and where to set up. When to call and when to quit.
And most importantly....NEVER shoot until you can POSITIVELY identify your target and know what is beyond it.
If you have specific questions...we are happy to help with them, but we can't provide a Coyote Hunting Tutorial here...it is too complex.
Spartans ask not...how many, but where!
