What to put on bow

[BrotherJim]

I just pulled the trigger on a g3 helix 12 mega + for the console

now need something up front for bow, going be another helix 12, but do I need just a cho unit or one with DI only I could use with a TM ducer
any help much appreciated I’m not ruling out mega 360 capability in the future I have an ultrex TM no I pilot
thanks in advance

To run a MEGA 360 takes a MEGA SI+ or MEGA DI+ model.

If MEGA 360 is in your future, it can be used alone connected to either Imaging+ model to provide 360 and Side Imaging ONLY. BUT if you want any other sonar technology including Depth, you need a source for at least 2D HW sonar.

The DI+ CHO doesn't come with a transducer and is that way for those that have a Minnkota trolling motor with built-in MEGA DI transducer and don't need an external transducer.
