i have a foxpro fx-5,shockwave,and a ico tec gs500 with the tony tebbe sound libaray.the ico tec is a cheap caller that will work but the sound quality isnt comparable,that being said,its not as loud either-but -depending on your needs it would make a great little caller.the ico tec remote is far superior to either transmitter to operate the shockwave or fx5.the ico tec is simple to load sounds ,lighter,but it will operate at a distance that you wont even be able to hear it.
