sku# 1501058010
An essential coupler for your Garmin network With this special PoE (Power over Ethernet) isolation coupler from Garmin, you can connect underwater lighting, a thermal camera, or a boat stabilizing system to your compatible Garmin GPSMAP Series chartplotter. The coupler allows the new device to connect to the Garmin Marine Network, and it's very important to use it - the network won't work properly without it and you could even damage the Garmin unit and/or your PoE device.
