The silicone Lo-Cover, with lanyard, is a flexible PVC cover for the 2, 4 and 6 function standard transmitters. The hand grip design gives added protection against accidental damage. A lanyard with swivel hook allows the transmitter to be hung around the neck when not in use. All transmitters are supplied with covers when initially sold, except Part 9200. In the US the Lo-Cover is included in the price.
