Initial test using a cell phone as an electronic game caller

[Kain]

will have to give this a try, but I am not sure you can use electric calls while large game hunting. but the Yotes. 

Perfectly fine to use electronic calls for all big game except deer. 

13. U sing decoys and calls:
It is illegal to hunt waterfowl, turkey, or deer
with the use or aid of electronic calls and
battery powered or other electronic devices as
decoys.

I used my cell phone and a Cass Creek Power horn speaker ($40) for two years before I bought a Foxpro Spitfire.  Worked great and called in lots of critters.

Very nice!!!

in the small game forum on this site is a link to where I got the calls I use. The 30 minute call doesnt do squat. In fact I see NO animals with it. However the 7 second cottontail call is amazing. Ive called in a lynx (yes it was a lynx) and even a red tailo hawk with it. Ill be keeping that for next year!
