Default New Airmar B175 CHIRP transducer to fit SS264 and B164 hole size.

Coming late October or early November from Airmar is the new B175 flush mount CHIRP transducer. This transducer is designed to be used with the CHIRP / Spread Spectrum sonars now just coming onto the market.

For those who now have the SS264 or B164 transducers, the B175 will fit the same hole size ( 3 3/4") .

The B175 will be available as a flush mount in in Low, Medium and High frequency ranges and in in 0, 12 and 20 degree tilt angles.
The B175 is designed to be used as a paired system .
The B175's operational paramaters are expected to be the same as the B265.

And just in time for X-mas as we all need more stocking stuffers.

Thanks for that info.

>> The B175 is designed to be used as a paired system

What's that mean? And will it work with existing sounders before they're upgraded to CHIRP?

The B175 uses two transducers....For example one will be the Low frequency band ( 42 khz to 65 kHZ) and the other the high frequency band ( 130 kHz to 210 kHZ)

Or the you can use Low freq band and the other can be the Medium freq band...the B175 system will allow the boater install which two frequency bands he finds best for his fishing needs.

( Only the flush mounted CHIRP require two transducers. Most other CHIRP transducers like the transom mounted Tm265 or the tank M265 require only one transducer)


Concerning using the CHIRP transducers with non CHIRP sonars:
.
This is a FAQ from Airmar concerning using the CHIRP transducers with standard tone burst sonars:
http://faq.airmar.com/index.php?acti...247&artlang=en

But CHIRP transducers can be used with some sonars that are frequency agile (Where the sonars can select different frequencies from high to low to operate on) such as the Furuno FCV295, 1100, 1150, BBFF3 and DFF3.

For example: The FCV295 allows the user to select any two frequencies between 28 kHZ and 200kHz to operate on.

With these type of sonars you will not get CHIRP but the boat owner can tailor the sounder
to operate at different frequencies and the CHIRP transducers will give enhanced performance.

Thanks. So we're talking around $3700 msrp for a Garmin Chirp upgrade? GSD26 plus 2 x B175?

If you choose to go with the B175..two flush mounted transducers.
There is one other flush mounted CHIRP set..the B75...they use a 2 13/16" hole size.

If you choose to use the TM265, M265, B265,
B265 you only use one transducer.

Gil: Do you think the new CHIRP sonars will be able to use either a CHIRP or tone burst transducers? If you currently have a good tone burst transducer and you had the ability to connect both CHIRP and tone burst using an Airmar connection box you could retain the tone burst as a back up. Don't know if this would be desirable or not - just an idea.

Interesting idea .

But how many boaters use a back up transducer now?

I think that once someone ( My self included) forks out the kind of money one of these systems is going to run... it better darn well work!

If not...there will be some mighty unhappy campers
But from what I have seen so far..great systems.

Thanks Gil for the heads up. It is awesome news!

Up here in the PNW, and only having room for one, which unit would you get? Low or high freq's? I assume a high since over 800' is of little use...

Default Thanks Gil

As the others have said, great info.
Another question for you: I have the ss264 pair installed with BSM2 and understand the hole size is the same as the B175 pair, but would the cabling also be the same? If so it sounds like a rather simple swap and I'll have the SS264 pair for sale soon!

You will need to use the cabling that comes with the B175's....you will be going to a di-plex cable system.. completely different from what you are now using.
