"I wonder if the system mentioned would b better than the $500 FoxPro." You can call coyotes with your finger nail, hand call, cassette player, electronic caller, and yes your cell phone. All of these will work but there are a few things that set the FoxPro apart from the others. Outstanding remote which is easily seen at night with great range and simplicity. The unit has great sound and volume. Fox Bang which changes the sound automatically when you shoot. It comes with 100 sounds of your choice. There are more. These are just the ones I use. Oh, and yes they have outstanding customer service. So to answer your question, NO.
