there is not much differance between the two calls. i have a western rivers my friend has a fox pro. they both work real well. but we use mine the most because we can change the sounds in about ten minutes on your own computer. fox pro is a pain and most have to be sent into the company for a sound change. any cd or tape can be recorded and changed over to a mp3 right at home. so this gives you hundreds of differant sound to load on the caller. i just save all my sounds in a folder and i can listen to them and load them at anytime. you get everything you need to do this with when you buy the caller. all you need is a usb connector and that's it. i don't know about you but the same old sounds over and over get old real fast. this way you can change the sounds to match the time of the year it is. service seems to be very good also. i dropped my call and broke my antenna. called western and i had a new in three days no charge.
