RX-070 Micro ReceiverThe RX 070 Micro Receiver is our newest receiver designed with the smaller dog in mind. Approximately 20% smaller and lighter than the RX 090, Its unique design allows the user to turn it 90 degrees on the strap so contact points can be fore and aft if necessary for a very small neck. Contact points are 1 apart from one another rather than the traditional 1. 25 span. Compatible with all current transmitters including the ET 300, ET 400 and EZ 900 and
