C127 w/ CP370 or 470

[MAK1377]

Thank you for your reply. Just to clarify one of your recommendations, if I install a 1000w high prtformance transducer, such as a B164 using Raymarine adapter cable E66066 and connect directly to the C127, I may see added performance and detail for the relatively shallow depths that I fish or would I need to also add a CP370 that uses 1000w to take advantage of the 1000w-capable B164 transducer?
