Are these HB part numbers Mega units?

[txsunfish]

Can some one tell me if these part numbers are Mega units for sure? I don't have access to the boat 410370-1 (DI) and 410380-1 (SI)? They are supposed to be G2N's. Thx.

410370-1 is the G2N non-MEGA DI model.
410380-1 is the G2N MEGA SI model.

410520-1 is the G2N MEGA DI model.

Depends on what "fine" means.

You can't use DI with the Minnkota MDI transducer.
You need to exchange for or purchase a DI trolling motor puck if that is bow is where the unit will be.
