Works great.
Installed this on my Sea-doo and it worked perfectly with my Garmin 73v. Very happy with it.

Love this!
Installed this transducer to our 2022 Seadoo Switch. So far so good no issues whatsoever! Going this route is cheaper than buying the kit from the dealership. I watched a video on YouTube on how to install but literally super easy install.

Works as expected.
Not much to say, it works as expected. Good in hull transducer paired with my Echomap

Loses function at shallow depth…
So installation was easy, followed instructions to the letter. Good quality readings at depth, even with 30mph across the water. It correlated with my higher quality transom mount transducer had read. I bought this due to the cavitation issues at speed with TM mounted. HOWEVER, it is essentially useless at <8ft of depth. It’s almost as if it is confusing itself as it more or less seems to be registering the bottom but freaks out, and this is irrespective of movement speed. It does allow me to chart some of the skinnier water areas at planing speed which is why I bought it, but would have to manually switch over to TM transducer when in shallow water…

Works in my Ski Doo
I bought the kit so I could install my gps/depth finder in my skidoo. I have the transducer mounted in the back near the center and this kit provided the exact angle I needed to get the transducer to point straight down through and angled hull. A little glue and anti freeze and it works like a champ. FYI, I am too cheap to pay someone else $300 to install my gps/finder on my jetski (a 1 hour job). I won't do something like this unless I am pretty confident I can do it myself. I did a little "JFGI" (Just Freaking Google It) and found a lot of people doing the same thing. Trust me when I tell you. I will not compromise my jetski and this was an easy install. I was more nervous before I started than while I did it.

Works for a boat mirror
Mounted this on our center console boat. The one mounting screw snapped while installing, but everything else about the design and construction is good.

チャープ発振でヤリイカが群れでいれば反応します。
今までは振動子を上げ下ろしして使用、不便なのでインナーハルへ変更。 GT-51振動子で映ったヤリイカがこのGT-15振動子、それもインナーハルで映るか心配でした。 多少の違いはありますが問題なく使用できました。

Works very well. Installation requires some handyman savvy. Needs a matching connector cable.
