Using a Point1 antenna and putting it near your transducers on the stern will increase accuracy when marking waypoints from the console unit but the best thing about it is the heading sensor. The heading sensor will keep your waypoints on the map oriented in relationship to the direction the boat is pointed.

I have a Point1 and it is connected to 2 units at the console and a bow unit. I have mine set up to use the point1 to supply heading info to all of the units. I have the console units set to use GPS from the Point1. The bow unit uses its internal antenna for GPS since it is right by the Trolling motor that has the transducer on it.
