See if this answers your question : How to Use More Than One LiveScope Transducer | Garmin Support
If I wanted to run 2 livescope transducers one on trolling motor and one on a transducer pole. Will one unit be able to do this if there are two ports on the unit.
Yes, but still need 2 GLS 10 black boxes.
Never mind my original thought I misread. Lol
Ultras you can hook both up to and will need two black boxes. Don’t know if any of the GPSMaps can. Sure the higher end models have two ports.
My buddies who tourney fish in Texas have two. One run on the ultrex shaft and second runs on a homemade edge shaft with cable steer as well. The edge is just head and shaft with no motor. Separate lithium batteries just in case!
