Do I need a External GPS Heading Sensor
I have two questions. I have just installed a Helix 10 DI Gen 3 on my console and want to get the best performance from it I can. I also have a Helix 7 SI DI Gen3 on the front deck. I have them linked together with an Ethernet cable. Both units have 360 capabilities. I want to use the 360 transducer on each unit separately [using each unit by it's self as well as both at the same time]. The 360 transducer will be mounted on a Da Ducer and the Helix 7 transducer on the trolling motor. How do I run the DI transducer and the 360 transducer on the Helix 10 DI on the console. And one more question. On the Helix 7 DI/SI unit on the front how do I run both the DI/SI and the 360 transducer on it? Sorry for the long post, but I'm technically challenged.
I may be getting older but I refuse to grow up.
