I have a 899 HD SI and a Helix 9 mega SI mounted at my console. The two units are networked via an Ethernet hub. I have a shoot-thru transducer and a mega y-cable so I don’t lose 2D when running. The 899 does not have a transducer connected to it because I primarily use it for mapping. My question is should I be able to pull 2D from the networked helix unit even though it is mega/chirp?TIA
