First of all, let me just state that my english might not be too good....however, my need for help is big so ill do my very best to make it as understandable as possible
I have bought a Hobie Outback (2012 edition) which sadly is not "Lowrance ready". I have tried to install the transducer in the hull of the kayak with some "Hobie Marine goop". However a big buble of air in the glue resulted in some inteference on the screen
The image was like this
After having tried all possible settings i unmounted the transducer just to see the big gap of air in the glue which can be seen here
So i took off all the glue and concluded that i had found root cause.
I tried a new mountingmethod using some sanitary putty (http://www.unipak.dk/en/node/42
That gave a bit better picture. The upper part of the screen had a more clear picture but still a lot of interference on the screen.
The screen now looks like this
Compared to the old setup the upper part of the screen has improved a lot.
So i rushed back home to figure out why the picture was not close to perfect. I found out that i had not inserted the transducer close enoug to the hull. approximately 1-1,5cm of sanitary putty was between the hull and the transducer. Now i have mountet it again using a lot LESS putty. I think the transducer is less than 0,5cm from the hull of the kayak.
tomorrow ill go and see if it is better.
So why am i writing this "cry for help"??
Well...Furthermore suddenly the DSI did nok work last time i was out to try the "sanitary putty-setup". The symptom on the DSI is that the seabed is not shown on the screen. I have read in another forum that another user has experienced the exact same symptom using the sanitary putty. With the marine goop the only thing that seemed to work was the DSI. With the sanitary putty the DSI is not working.
So i have this gutsy feeling that it still wont work. Maybe im a bit closer to the goal having inserted the transducer closer to the hull. But the DSI not working at all...thats a mistery..
So my motivation to ask for help in here is to ask if anyone has had succes installing a Lowrance HDI transducer in the hull of a Hobie Kayak which is not "lowrance ready"?
One important note is that it seems that most transducers are working fine...its so far only the HDI transducers that are experiencing these issues.
The transducer is this one
