I am happy to see that Furuno's new Chirp unit (BBDS1) is listed on its products page, along with a list of compatible transducers. Two questions:
The product description emphasizes the unit's bottom discrimination capabilities, but not not mention "chirp" or any enhanced fish finding capabilities. Is this unit different from those of competitors in these respects? Does it offer enhanced fish finding?
Also, the list of transducers does not include the 509 (or 599), which I believe are Airmar numbers, but I note that the 209 (also an Airmar number?) is shown as a compatible transducer for the DFF3? Is the 509 a good choice for the BBDS1? I believe the 509 is capable of handling 3kw, while the BBDS1 seems to be a 1kw unit. Is that why it is not shown a compatible? Is it safe to assume that, like the DFF1 which was ultimately followed with a DFF3, there will be a 3 kw version of the BBDS1 released some time in the future?
