This item is The Remote PRO Receiver Module ONLY, The Remote PRO Transmitter will also be needed to control this receiver module. The Receiver module operates on 10 different frequencies but you can use the same PRO transmitter to control all The Remote PRO Receiver Modules. This Remote setup is perfect for multiple feeders that are close together so you can control which one spins independently. Easy to install wildlife feeder remote, control your feeder with the push of a button from distances out to 175 yards. Don't be fooled by the $30 big box store feeder remote controls. If you think you are getting a better deal there, think again. Be prepared to also purchase 2-3 extra solar panels to insure your feeder battery will not be dead a month after you hook it up. You get what you pay for and this remote PRO is the best one on the market!
