Spotted Owl and Sheister
,It really doesn't take that much to get set up predator calling now days.Some of the payers are priced at around $100.00,and go up from there.That along with a speaker, and some tapes,and you are in business!!!
I use a long range speaker exclusively ,for my calling.Just make sure the speaker has good sound,and no distorsion or hiss.
Don't forget that you have to use an amber colored light,or you will spook the cats when you hit their eyes.I have always called in the cats at night, using a cottontail rabbit in distress tape.They come in very slowly,and very cautiously -down wind. So,make good use of your cover scent(I use fox P),on a small pad on your clothes,on your boots,around where you are sitting,a few drops around your caller-and along the speaker cord! I use a 50 foot extension on my speaker cord,-to get their area of focus and attention away from me.I like the remote idea,but instead devised a timer to start my player with up to 1 hour delay.I plan on taking my coyotes,bobcats,and possibly a lion at long range,and want to be completely out of the picture when they come in.This will give me as much time as I need,to set up and get back to my position.
Sheister,I would say that the fawn in distress tape should be a good start.
I played with a mouth blown version last month in Arizona,with VERY POSITIVE RESULTS !!! But,I wouldn't write off the other tapes for effectiveness.
I can personally attest to the effectiveness of the squealing woodpecker tape.I watched a red fox from about 35 feet,come to and home in, like he was laser guided, to my speaker.I couldn't imagine any predator passing up any type of injured bird/animal free meal out in the wilds.
You will just have to experiment with the different tapes,-AND VOLUME.
One thing to remember

ut your cover scent on your boots BEFORE you get to your huntng area.You don't want them to be circling in towards you,and run across your human scent.
I have never used(YET) a ghillie suit, most outdoor catalogs have them.But,they are expensive.....
Spotted Owl and Sheister-sorry for the book,but I have always loved predator calling!
Any more Q's-just ask!
Merry Xmas to you,and all members of Moosies !!!!!!!!!!!!!!
