I have a Helix 5 CHIRP SI G2 that I connected to 2 Transducers. One is mounted on the transom and is the transducer that was supplied with the unit. The second transducer is mounted inside the hull for high speed operation. When in sonar mode, there is a setting for selecting the connected transducer. Since I have the Y cable what should I select? , There is one option of Compact SI Transducer another says 455 -? KHz SI Transducer then there is an 85 - 200 KHz transducer.
When I run, I get a black and white chart that I wish was in color.
Any help?
