Transducer/Sounder Help- Elite 7 Ti

Hi All,


Another Transducer positioning and sounder set up question.


I have an Elite 7 Ti with the Totalscan tranducer and having the common issue of it not reading at speed. I had it out to 40m the other day and couldn't read anything over about 4-6 kn. Over that I had to dial the sensitivity and colorline WAY back, to the point that i'm not confident i'm actually going to sound anything. Then when I slow down it's basically a blank screen until i dial it back up. I was running it in High Chirp mainly but also tried med. chirp and 200kHz, same reults basically.


I understand it's all about transducer positioning but I have tried a couple positions (inside and outside of mounting plate) and as low as i can go. Anyway, I have attached pics of the current (and previous, inside) positions for your comments/advice.


I have also attached some pics of out at 40m last week, both at speed and drifting. Also, feel free to let me know what i'm looking at in terms of bottom. I did manage a Black ass and size Dhu off some of it.


Thanks in advance.

I have a question

Tue, 2020-01-14 16:47

 Did you run your tranny wire from the head unit to the transducer, completely seperate to any engine wiring or power / battery wires? From the looks of it where your screen has heaps of green all through it (first few pics), it appears to be getting interference from somewhere. If it's near engine / charging wiring, that would explain the slower speed having less interference (slower engine rpm therefore less charge output). 

the only problem ther times I have seen something similar is if you have a phone or GoPro plugged into a cigarette lighter plug charger on the dash or near the screen. Whilst plugged in for charging, it made the screen experience heaps of interference. 

hope that helps

Thanks for the reply scano. I

Thanks for the reply scano. I can certainly look into that, from memory it is on the same side but not next to the main power cable. I did try revving the motor which showed no interference at all, but that's obviously in neutral and not loaded up.

what boat do you have?I have

what boat do you have?

I have the Elite 7ti also, on my 660 Trailcraft, which have the same problem & starting to get really over it..

Heading to a Sounder night @ Tacklewest on the 29th which hope to pick up some tips / look at alternative options within a certain price range.

will be following this thread though

Quintrex Coast Runner 480. Only had it about 8months, but very happy with it. Had the Elite 7 ti sounder for a few years now and it was similar (but slightly better) on my dinghy.


Reading a bit it seems like a comon issue but others are claiming to get them reading well at speed. Seems to be very sensitive to tranducer position, like most trannys i suppose. I might try running the cable differently and raising the tranny.


Let me know if you come away with any insights/solutions.

Interesting read on the setup

Interesting read on the setup of your transducer.

Specifically points out that if the transducer is out of the water it will not read bottom.

It also says :-

. Hold the whole assembly up against the transom or transom
step to the desired position. If mounting on the transom, align
the bottom of the transducer with the bottom of boat. Use a
pencil to mark the pilot holes (D). The transom mounting plate
has screw slots for adjusting the transducer position height

Holding your ruler underneath the hull it should line up with the bottom of your transducer (sit on top), from your photo's it looks to high to me ??

Your side and down scan will only work at slow speeds, chirp should read no problems at speed. Are you running chirp only at speed ?

I have pretty much read the manual only and seen your photo's so just a guess really. Hope that helps.

I'll have to read the manual

Wed, 2020-01-15 12:42

I'll have to read the manual again but i was under the impression that the join line should line up with the Rule/hull. I agree that it may be too low though, worth a try.

Yeah mainly run High chirp, but did experiment with 200kHz. Thanks for your reply, really appreciate it.

Any general comments on the sounder reading/ground (at drift) though?

 the first photo looks like it could be facing forward too much depending how you boat sits when up and about on the plane

I have the front of the boat

I have the front of the boat up high and the driveway slopes away so it probably looks worse than it is in that photo. The rule is inline with the bottom of the hull though, but i'll check it again. Thanks.

You are not alone

Google elite ti fishwrecked and read the threads.  Mine is hopeless with totalscan unless I am doing 5 knots or less and it is calm, same problem all depths, when drifting I get a good picture.  I have tried so many different spots for the transducer the mounting board on the transom looks like swiss cheese. I siliconed a hds DFSHBL 50/200 khz inside my boat, firing through the hull, it reads great at all speeds (over 30 knots), but you need a solid glass hull to shoot through.

Thanks for the reply Wagyl,

Thanks for the reply Wagyl, although it doesnt sound encouraging. I will persist for a little bit more and try a few different positions, general consensus is that it might be too low, after that it may be a transducer/sounder upgrade.


Thanks again.

 I have an elite 9 ti that I use for maps, the totalscan is still hooked up and I read bottom at 20 knots. My old man also has one that is his primary sounder and his also reads bottom at cruising speed without clutter.

That's encouraging. Are they

That's encouraging. Are they both transom mounted? Do you know if the hull is inline with the bottom of the transducer or the join line, like mine? Thanks for the reply.

 i'd be very interested to see the set up too. i have the elite 9 with same problem with noise on the screen at speed.
