Last season was short for me and didn't codfish with it in deep water, so I can't answer that question. So far just used it for bass, blues and most important bait. I like seeing the bottom shape most of all. No doubt the more powerful machine would be better but if your off the bank in 275 that isn't that deep relatively speaking and would hope 600w would still work. What kind of ducer do you have. If I remember correctly I think mine was a B744V bronze thru hull, this was the upper end of the middle range but the best one for 600w.

Did you have good results one the bank in 120'?

I am sure you have figures how to zoom in on just the bottom 15' or so.
