Dff3d Transducers

Postby Easygoing » Tue Jan 02, 2018 7:22 am

I have purchased a TZT2 12 and plan to buy the Dff3d black box. I've attached a pdf with Dff3d transducer options. There seems to be limited information online regarding the specs of these transducers. Here is a list of the Dff3d transducer options:

165T-B54 Bronze Thru-Hull Multi-beam Transducer
165T-B54 Bronze Thru-Hull Multi-beam Transducer
165T-TM54 Transom Mount Multi-beam Transducer
165T-50/200-SS260 DFF3D 50/200 Stainless Combination Thru-Hull
165T/265LH-PM488 DFF3D/CHIRP Combination Pocket
165T-50/200-TM260 DFF3D 50/200 Combination Transom Mount

Does anyone have information on the Q values or minimum depths of operation for all of the above?

Easygoing,
The combo transducers use the same three elements as the B-164 so in theory the "Q" should be the same i.e. 7 for 50Khz and 17 for 200Khz.

Does that pocket mount transducer have to have the face of the transducer in the water or can it be mounted in hull? Stepped catamaran hulls kinda get screwed on transducer options. Its either gotta be an In hull in front of the steps or a small thru hull in front of the steps. The b54 thru hull I think will hang down too much and also interfere with the trailer bunks. Are there any other options for transducer mounting placement? transom mount is last resort because of performance at speed behind the steps

I'm hoping at some point furuno will come out with a pair of flush mount thru hull transducers for the dff3d system. One that will go on either side of the vhull and work together. I don't want a fairing block and a transom mount isn't ideal either

Tailin Strange,
It is highly recommend to have the face of the PM transducer in the water. I totally agree with you about mounting transducers on cat hulls. Do you have a flat spot just forward of the transom?
