Raymarine Transducers VS Other Brands

[GMac7]

Hi All,

Hoping I could get some feedback on the various transducers available within the market. I'm refitting the electronics on my boat with new Raymarine gear. I've decided on the C127 with built in sonar (rated to 600W)

Here's my dilemma: Raymarine offers a few different plug and play 600W transducers compatible with the deadrise of my boat. I plan to do most of my fishing in and around Cape Cod Bay and the islands for bass/blues/cod/etc, with a few scattered BFT trips here and there. Do I need to upgrade to a separate unit and pair it with a 1KW transducer, or is 600W enough?

Also, how are Raymarine's transducers compared to other brands such as Airmar? I believe with an adapter cord, I can connect any transducer to the machine.

Thanks in advance!
