Handy to see how deep it is sometimes. Especially in the bay. #
When you say gone is that everything or just picture of the bottom.

Hi FF,

It seems to depend on conditions, bottom picture drops away pretty quick on a rough day, but on a fairly calm day we can stay with a depth reading to about 25knts in 60-100mtrs.
Anymore than that & depth reading drops out also.

You and I are now at the same point after basically trying the same things with the 600L / P66 units . Nothing wrong with the sounder - it's the hull . My hull has the same deadrise like yours and it's always going to make things difficult with the transducer but hell I will take the better ride anyday .. Yours is now mounted in the same position as mine . It's the best compromise so far I have found . It will hold bottom at speed in good water but loses it or has bad returns in other than that . A piece of advise though now - take it for a run before the next offshore trip and check where the spray is deflecting towards the motor . You will most likely need a deflector on the inner side at least . Mine was shooting the spray towards the motor intake at speed .

Thanks Chris that's great advice on the spray.
The weather on the weekend prevented a run. But the forcast Tuesday looks awesome.
I think I'm coming down with something (cough).
Will let you know if it works.
Cheers,

Sometimes I amaze myself.
Here is another photo. I suspect my problem is further up the hull. I reckon the strake that finishes halfway uo the hull directly infront of the transducer is the problem. I didn't even see that strake...

I think my only option is to drill more holes away from this point to the right between the two strakes.

Cheers.
