My son just bought a new Ipod and he downloaded an app with a lot of good crow sounds on it. I went out and bought a relativly cheap speaker for it but it does not have near enough volume to bring them in from far. (I know you get what you pay for) Before I lay out the cash for five more speakers hoping to find the right one could someone steer me in the right direction as to which one is the loudest without busting the bank account in the process. (There I go, being cheap again). Thanks all.
Plug into car, use a bull horn, buy a cass creek big horn, build your own using radio shack parts, follow directions posted by varmint al on his website, visit the electronic caller forum on predator masters and build your own, etc. What app did he download?
