Hi All,
I have a Lowrance Elite 9 Ti sounder and transducer set up.
It came with the boat, and it should be a decent kit, however I am getting the following display.
I'm new to expensive sounders, but I know I can manually adjust the sensitivity, but should I have to ?

This is what I'm seeing is this normal ?
And this is how my transducer is mounted....

I think it says to avoid planning stakes. But you should be able to get rid of that stuff with adjustments

It does look like the gain is turned right up, where the transducer is mounted you will get a lot of white water while underway which will reduce your ability to sound properly. It looks like it was mounted previously to the left, wonder why it was shifted as that is the better spot for it.Originally Posted by docaster

Whats gain ? How do I adjust it ? I have everything set to Auto.
As for the mounting, I know the previous owner upgraded the transducer, so maybe the old one was there. Is it worth me moving it back ?
I really dont like drilling holes in the transom.
It's a bit hard to see exactly in the pictures, but, it does appear to be tilted up at the very back, I wonder if it's getting bubbles under it? Those long transducers can be finicky to get right sometimes.
From what I'm seeing
This really is just about adjusting your settings - play around with the sensitivity & colourline . Modern sounders do a good job with auto settings but it is best to learn how to adjust these to optimise your view .
Does your sounder have a surface clarity function - high / med / off ....... That clears up the top part of the image
To be perfectly honest - your image isn't that bad as it looks like you were underway when you took the photos ....
A suggestion is to go into demo mode & play around with your settings - you'll get to see what happens when you adjust the sensitivity & colourline;
With regards to your transducer location - It looks OK but a little low . You should have some scope to move it up or down an inch or so . Get a long straight edge like a spirit level & put it up against the bottom of the hull (flush) . Then see how level & the height the bottom edge of the transducer is when compared to the hull . Ideally The bottom of the transducer should be inline (or a fraction lower ... 2mm) . This will limit interference (bubbles ) & allow you to read the bottom at a reasonable speed ; These long transducers do take some tweaking to get them right
This is my lowrance 3 in 1 Active image height . This reads quite well at 40km / hr transducer height (2).jpg Note : I have mine slightly tilted down as I generally sound in shallow water at low speed .
This is certainly too low

A straight edge hard up under the bottom of the boat is the best way to set them up, just move the transducer down until it's flat with the straight edge and tighten it at that.
My apologies , I used gain instead of sensitivity, very old term from paper sounders. The strake (red dot) is going to create a lovely trail of bubbles as they come off and wrap around the transducer while under way and create that curtain of noise. There appears to be indications that a tranny was installed lower on the hull - red arrow - and this is where my preference would be. I'd get a piece of scrap 6mm ally, tap some holes for the tranny bracket so you can adjust it up or down and screw it to that spot or you can buy SS propriety ones to do the job. The holes left from removing the tranny in the current position can be cleaned out and filled with resin and painted over with some flowcoat, easiest way to fill the holes is to use a syringe, most fiberglass places will sell them. As Chris has said long transducers are a pain to set up and sometimes shallower exposure is better than deeper exposure to the flow of water as when buried too deep in the water they will want to generate their own bubbles as the water flows over them.

Go into the menu and look about for settings , should be a senesativety bar come up . Adjust up or down to suit your likeness.
But as Chris said its not all that bad depending if that pic is whislt planing or going slower eg; 3 to 5 knots??.
Offshore I get it looking sometimes like that at speed, still trying to find the sweet spot with my new Lowrance HDS, not a fan of them except I needed something that interfaced with my Motorguide. Smidsy is in the Swan River in only 7 - 9 m of water and he should be able to sound at 20 knots or higher with complete clarity, I know I can in the Pumicestone Passage but once in the swell and chop is where I am finding I still need to fine tune it. I still believe that the water coming down that vertical strake right next to the tranny is the main issue.

Yep, bang on, trolling for tailor on the Swan river, and im going 4 to 5 knots on flat water. I had forgive the interference previously as I was usually in choppy water, no excuses this time.
The previous owner had it much lower in the water, and while it was much clearer, combined with the hydrofoil, it would tip the boat over when planing. So I removed the hydrofoil and moved the transducer as high as I could within the bracket.
Thanks everyone for the advice, seems most agree its in a bad spot and its slightly too low.
And thanks for the tips about using a spirit level to get it flat with the bottom, I previously thought that that would have been too high, but its makes it fool proof.
Looks like I'll have to move it to the old spot, and plug the holes.
You say you had a foil on the motor and it made the boat misbehave on the plane? I wonder if the motor is mounted too low and causing bad spray straight onto the transducer? Before moving anything, try the straight edge trick and give it a go.
Which part of the transducer though, considering the hull is on an angle and the transducer is horizontal?

Have a look at Chris's post above, only the bottom of the tranny needs to be below the water, usually there is a defining line running along the tranny and that's as deep as you need. Too deep and it causes issues as well.

Hi All,
Firstly I did everything I could to straighten the pics, but this forum has always made my life difficult when it came to uploading pics, and always rotates the pics I upload, even if I counter-rotate them to correct it ! So I gave up.
Anyway, I finally went and re-mounted the transducer.
Like an idiot - when I finished, I realised the motor was trimmed out very far for transport, and I would need to trim in.
This was when I realised why the previous owner had moved the location of the transducer !
While its not actually touching the motor, its super close.
So, I'm tempted to leave it and see what happens ?
Otherwise where do I locate it ?
Also, By the time I'm finished, as I used the safe option of screws with silicone to seal the holes, the transom is starting to look like a rebellious teenager with all the jewellery.
What's the safest way to seal these holes below the waterline ? Gell coat alone would be weak wouldn't it, but an epoxy base will run out of the hole ?
I'm tempted to bring it to a professional, getting the boat serviced on Thursday, might ask them to mount it for me ?
