I have owned on my last boat the 600L and liked it very much. On my new boat (Pacific 23) I am probably going to buy the same. I was told by Furuno that if I used the 1kw transducer the 525T-TMD ( M256 with transom mount bracket) that this would improve performance significantly. I fish in shallow water up to 150'. Is anyone familiar with this transducer?
Does the 1 KW make a big difference? Are there other models that are not so cumbersome?
Thanks

I dont feel you need 1kw on a 350watt machine for shallow water, the 600 watt tilted element is a good option, if you want a transome mount a p66 is very good

I have a tilted element Airmar atached to a 600L and it is an amazing combo. Try it, you'll like it...

What transducer did you have before?

CMP

None, it was a new install all-around...

CMP - What is the model number of this transducer you refer to (tilted element 600W)?

Who makes it?
And, is it Transom mounted or other?

It's aa Airmar B60-12. I bought mine from BOE, a THT sponsor. It is a flush mounted thru hull...

it seems like this is a recurring theme, and i hate repeating myself, but the 1kw 'ducers aren't better with a 350w machine because of the power handling. they are better because they are higher quality/cleaner/more accurate. anybody that says the m260 1kw 'ducer is overkill for the 350w 600l machine is wrong. now, is it worth the money over the transom mount unit which works ok for $55? well, that's up to the shopper.

It is not the additional cost that is the problem but the size of the 1Kw unit. The size of the transom mount 1kw is huge and I am told can cause problems at high speeds.

Thanks Chainsaw for restoring my faith in this exact issue. I have read all the negative stuff about putting a 1KW ducer on a 350W 600L - but still think it is the only way to go without any compromise to visual separation and stability on screen.

I have spent countless hours reading the GOOD OIL on this forum and it is darn GOOD - but tends to circle alot without clear definitive agreed factual information. Is this just natural or should we intelligent human beings get our act together and maybe write down in summary format what is fact and what is not - about transducers - everything! (from type, installation, sounder compatibilities, photographs, physics behind travelling sound waves, etc..)

Otherwise, this perpetual repeated discussion will continue indefinitely..

Maybe as a read only page (but can only be edited by those who really do have the facts) would be great start..

I would love to see this happen - would reduce repetition and focus our thoughts towards catching FISH!

final facts

E Fitzgerald

The 1kw transducer has an array of piezoceramc elements inside as opposed to just one inside the lower-rated transducer. What that means is 1.) greater transmit sensitivity. Transmit sensitivity is how many dB of acoustic energy that generated by the transducer per volt of input energy. The 1kw transducer has (approximately) 6dB greater transmit sensitivity. And, since these values are measured on a log scale, that means 8x more power into the water for the same voltage input. Does this mean that you "see" 8x deeper? Well no - this is because of the transmission losses of the acoustic energy (spreading losses, absorption losses, target losses, etc.) And 2.) better receive sensitivity by approximately 4dB. Receive sensitivity is the ability of the transducer to receive acoustic signal and then turn that into an electrical pulse that the echosounder can recognize. Smaller (less intesnse) acoustic signals can be detected by the larger transducer. Is this definitive enough? All the best! E. Fitz.

I LOVE IT! Thanks - this is exactly what I am referring to - factual information.

Looks like we found ourselves the first of five authors suited for the role of the "Transducer Testament"..

How about it Fitzy?

Anyone else who wants to apply need to show what facts they have...

What I would love to see is a side-by-side comparison of single-element and multi-element transducers. I think that would convince a lot of people to make the plunge. Maybe someone has done it? All you'd have to do is have both ducers installed via an A/B switch (or just plug them in one at a time) and do screen shots over the same structure or bait schools.

I've got a 1KW Furuno fish finder (GP7000F NT) an would LOVE to see what I'm missing. Any vendors out there want to loan me a multi-element ducer? I’ll hang that rascal over the side and shoot some gee-wiz pictures as I compare it to my lowly $35 P-66--that does a pretty darn good job for the kind of fishing (inshore) I do.

Great idea - more factual information which cannot be torn apart. How about it Vendors - Not only will it help your PR but will also help your sales too!

Has anyone had issues with scratching the lense of the B-60 tilt element ducer?
