I had one of these when they first came out the only down fall is you are limited to a few sounds for predators,I have a foxproFX3 now but it cost a lot more,yodeldog3 has a good point if you buy a prey master you could buy a stevens model 200 with the difference and have a new rifle,if you are set on a wireless model johnny stewart is making a wirelessprey master with all the call cards available your sound choice will be larger than the phantom pro from extreme dimensions,as far as funtional the phantom pro works good but I like the ability to change sounds as the season changes you are limited to one 12 sound card for the extreme dimensions phantom,I read an advertisement that they were going to have another predator card for it but I havent seen one for sale at any sporting goods stores or catalogs.The PM is a good call,I just wanted a foxpro and got it,I love mine,IF I RATED THEM #1foxpro #2prey master #3phantom pro if I rated them for best value it would be the PM you can get a wired one for $99 and buy sound cards for $20 each.What ever you chose it should be a good choice,the phantom pro only has 2 rabbit sounds,you can get a bunch for the PM and more for a foxpro,and as I've stated before rabbit in distress has killed 80%to85% of the coyotes that i've killed over the last 11 years,only about 2 months out of the year will any other sounds work better thats feb-march around here,when coyote sounds work better,If I remember the phantom pro has coyote pups and coyote howls and thats it,the PM and fox pro have a bunch of coyote sounds.Make your choice wisely for the money,check out several and listen to them they aren't all the same.these three have been good ones for me.
