Single/Dual Beam, 20/60 degree, 200/83 kHz. Not compatible with the Trident Ultra, as the Ultra requires the transom mount transducer and Ultra Transducer Kit.

Fits well in my Ocean Kayak Torque (2013). As the other reviewers point out there is about 28 1/2 feet of extra cable. The transducer isn't designed specifically for a kayak per say, it's more likely the scupper hole was designed to accomodate this type of transducer. That being said it seems like the best off the shelf option for Ocean Kayaks.
Functions as it should and serves its purpose. Managing the extra 20' of cable is a chore. 5' to 10' of cable would have been more than enough for most all kayak applications. 30' is excessive. Hummingbird Customer Service has been informed of the matter and sharply criticized for their recommended solution. Cannot say it is a "kayak" transducer due to the unnecessary, excessive cable length. Fits the modified scupper hole on my OK perfectly as should. I would have rated higher (*****) and highly recommended the transducer IF not for the lengthy cable. With that said, this transducer is better than the alternate (bracket mounted transducer) that may require drilling holes into your kayak. I wished OK and Humminbird could have gotten together concerning offering a cable length option (or two) to the kayak fisher...
The transducer works well with my Piranhamax 175 and fit in the scupper recess on my Ocean Prowler 13T. It installed easy enough and works well but it is clearly NOT designed for an Ocean Kayak. Ocean Kayak designed the scupper recess to fit the transducer, however the recess contour which matches the contour of the transducer is facing backwards which forces you to install the transducer facing in a backward direction from what is recommended by Humminbird. You would think that should have been better thought out in the pre design phase but I guess the slow speed of travel allows it to read the bottom accurately. The transducer is designed to work on a full size boat so there is entirely too much cable provided. I had to add a nylon washer to allow the nylon nut provided to tighten properly since the supper hole is just a bit too large and the nut would not seat properly without a washer.
Good choice for Ocean Kayak. I previously used thru-hull transducer attached to the hull with two sided tape and had problems with it coming loose while being stored upside down. I am confident this will stay put. I have not seen a better solution for a kayak than thru the scupper hole mount.
