lilabner, no need to over do it. Lots of new people spend to much money on things they don't really need. New hunters also tend to out think themselves.
Predator calling is simple, all you need is a call ( hand or e-caller ) and a rifle you can hit something with.
The sport nowadays is all about advertising and big money, just go out there and start calling.
Your set up ( stand ) is probably the most important thing you can do in predator calling.
A simple list of things to do.
#1-If you don't have camo, you don't need camo, just ware something that blinds in. Remember movement is your worst enemy.
#2-If you are using an e-caller put it in the open so the animal has to show it self. With a mouth call also try to call the animal out into the open but remember the animal is coming right at you, watch the movement.
#3-Look for signs, scat, paw prints. Hard to kill a coyote if it ain't there.
#4- Try to set up high so you have the sight advantage on your stand.
#5-Coyotes usually head downwind, so keep your attention in that direction, but remember they can come from any direction.
#6-It's always a good idea to spend alot of time at the range with the rifle you are going to be using.
