Which ducer to buy?

[Missouri Bushwhacker]

Installed new mega 10 with ducer on rear. What are my options for adding extra one at the trolling motor. I'm not real happy with just 2d sonar up front and the quality my US2 puts out is inferior compared to one on my mega ducer on the transom. Thanks.

The most flexible choice would be a HELIX G2N at the bow that would share Waypoints, Accessories, and Sonar from the console unit thru Ethernet ...

Any of the new HELIX G2N models can share everything from the Mega unit (except mapping) ...

I have a one head unit two station (bow and console) set up. What I should have said first was I want to add DI imaging to the bow location. Obvious choice would be a TM mounted xm9 20 msi but this is expensive and provides smeared SI on a turning TM that does little for me. Would a xtm 9 di 25 t or xtm 9 25 wide t be a better choice or is there other options as well that may be cheaper. I understand it may not be dedicated DI but that may be something I would sacrifice for price.

Related question is what 2d frequencies does the US2 ducer I have provide? Because it seems the quality of the 2d I get from my transom mounted xm9 20 msi t is much better than the US2 at the bow. If they are the same then I have a set up problem. If not a set up issue then is there a TM ducer with better 2d than US2 and also has DI available?
