On my new MEGA 360 when 360 is full screen I get the option to scan 360, left, Right ,,Forward or Rear, but on my split screen map / 360 I get a different option that only goes to about 30 degrees or so forward.
On the bow its a Helix 12 Gen 4 SI networked to Helix 12 Gen 3 SI and Helix 9 Gen 4 DI on console
Also I can be in 50 FOW and get depth reading of 2 ft or 700 it swaps from accurate to ridiculous constantly. That's from transom transducer from Helix Gen 4 , all 3 graphs get same reading
I did not have the correct Y cable for built in Ultrex transducer so I disconnected the Ultrex Transducer from the Bow Helix 12 and just run Mega360 on the Bow to get started. Is there any advantage or disadvantage to only connecting MEGA 360? I don't look at SI when I'm on the TM anyway.
