That depends what you’re comparing the 1,000 W transducer to. This summer I stepped up for a Furuno stand-alone sonar called the FCV588—it has a new tech called “Rez Boost” —-the advertising in so many words says .....” get CHIRP clarity with either a 600 or 1000 W transducer...”
I have a P66 on my transom (a 600W 50/200Khz skimmer transducer—-cost $ 70 on eBay). I used that 588 with the cheap old-tech 600W P66 Airmar transducer all summer and it was my go-to, bread-and-butter sonar, despite having multiple CHIRP transducers mounted and operable in my boat as well as a 1,000 W in-hull Airmar M260 which I easily could have hooked up to the 588 — but there was no need....with REZ-Boost, the 600W skimmer transducer was just right
In addition to Rez-Boost it has an predictive algorithm that gives you bottom composition—you can see in the following screen shots the bottom-composition on the bottom of the screen—-great for finding safe anchorage’s and for ferreting out halibut spots
The last picture is a screen shot from a very expensive CHIRP set-up just for comparison purposes. (Using too much gain, ha ha)
