Default Benefit of 1000w sounder?

Greetings, sorry if this has been addressed, search didn't give me any love.

I'm considering upgrading electronics from a 2003 Simrad CE33. The Humminbird (958c or 1158c) I'm leaning toward can transmit 1000w, but seems to require the proverbial "optional" transducer. Those seem pretty spendy from Airmar, can't tell if any from HB are actually 1000w transducers.

My fishing will be mostly bottom fishing in 300' or less, some trolling in generally same depths. May be some shrimping at depths to ~700', too, but less commonly.

Is there really a big benefit to the increased power, especially from the standpoint of the expensive optional transducer? I know I'd have a better chance of maintaining good sonar at speed, but any other considerations?

Thanks,

Chris

Perhaps a better way of phrasing the question is "what is the real utility of the expensive transducer?" I want the features and screen size of these two units, and they both have peak power of 1000w. So I'm trying to determine the real utility of being able to use the available power. I guess I could always start with the 500w transducer.

Are there many different lines of transducers that might be compatible with the HB units and can handle the higher power?

Simply this...

Transmit power in a transducer is not always the most important parameter. Its sensitivity and ability to detect the return signal is of prime consideration also.

The Airmar 1 kw transducers being of a higher design quality, multi element,lower Q units will give the sonar system definite improvements.

It then comes down to ones pocket book, and also if ones fishing conditions even rate a more sensitive system.

The 958C and 998c can pulse out up to 8000 W. But you have to use their special transducer. It's in the units manual which you can access online under the units page and support. The extra power is used to reach deeper than 1200' and I believe to improve the screen display.
