i started out with a small tape player and a horn it worked good but you had to becareful not to get things wet. then i went to a hunters buddy which also worked good but it was very heavy. then i went to a johny stewart prey master. but it locked up on very cold days. i returned it. then i picked up a western river with remote. seem to work real well. the remote worked out to about 200 yards and the volume was pretty good but you have to step down threw your sounds. stepping threw sounds usually worked ok but if it missed the signal then the wrong sound played. you could lose track of where you are at on your sounds. so i sold this on ebay. fox pros are very nice but they are to costly and if you drop it well keep your fingers crossed. i ended up with a simple set up that always works. it is a small mp3 player with a tiny amp and a small horn. the amp and mp3 player is attached right to the horn making it all one unit. it works great and along with my mouth calls and it will take more abuse that any of the others that i have mentioned. i have found out that the sounds do not have to be away from your area. just do not play your sounds so much. if you play them to much then you give away your location. i set the system up for just over $100.00. i found out it's easier to just keep it simple. just some of my trials and errors. hope it helps.
