Transducer Positioning advcie please(structure scan)

[yanjarra]

hey fellas

well its been a while between drinks for myself both in terms of fishing and ausfish due to a pretty hectic period. however i am raring to get back into it now ill have a bit more time on my hands and as such have invested in a flash new HDS structure scanner as my old sounder had nothing.

Could the gurus amongst us please provide advice on where i should be positioning the thing?

I really want it to be able to show bottom at speed, and bait balls at speed would also be nice. My previous sounder - a hbird matrix 12 did not do this- whether it wasnt good enough or it was the positioning of the tranny i dont know.

The first couple of pics with it quite low are of the way i had the old one. This did not show bottom and threw up a bit of a rooster tail which im lead to believe is a result of it being to low.

The next few pics show my new setup with the structure scanner and normal sonar where i am thinking I will put them. Do you think this positioning will be okay as I would like to get it as close to perfect as possible first go. Are the two to close together? Higher/Lower/sideways? Do you think the step I have them on will be okay or would i be better off attaching closer to the centre straight onto the transom? Only problem with that i think is theyll be to close to the engine.

On a side not is running the cable to the unit head with other electrics cables a big deal?- i know the manual says its a no no but i really dont have anywhere else convenient to run it.

Sorry about the tape and hands in the photos- necessary to illustrate positioning without having to screw the trannys down.

CHEERS

Pics 1 & 2 needed to be up about 1 Cm.
Pics 3, 4 & 5 need to be lowered about 3 Cm.
You will have a hard time getting a good reading at any speed due to the strakes and the step is not a continuation of the main hull.
Maybe you could get in closer to the motor on the main part of the hull, you need to make sure the motor doesn't hit the tranny at full lock and the tranny doesn't disrupt the water flow to the prop.
What's that silver bracket in closer to the motor?
Sorry to say I think you're going to struggle with this one mate.

well that sucks. i could maybe get closer where that metal bracket is, but if you get too close the engine noise inteferes doesnt it? I dont know what its for , was there when i bought the boat, i assume the previous owner had the tranny there at one stage and it didnt work out..

surely there is a work around, maybe i can have the step taken off the boat absolute worse case- would that help......

Just an observation, but will the sidescan get blocked near the top of its 180deg by the other transducer. Wouldn't it be better if the sidescan was where the old one is?

Another question that is related, I have been told that the Tanducer is always to the right hand side. Can someone give me the details why?

The reason i did it that way was because i thought the normal 2d sonar would be the best one to use whilst on the plane for bottom readings and looking for bait, so it would be better to have it lower in the water to get a better reading...

but yeh you are probably right., i dont know if at that angle it will intefere with the structure scan......that is what i was hoping to find out by creating this thread.....

in the words of bushy- "its hard to get good help these days"


ok than...

can someone even recommened a professional or guy to get in touch with on the north side of brissy who is clued on with these things i can take the boat to, to get looked at????

itching to get it done and go fishing

Surely there is a sales rep that sold it to the shop you bought it at. If any one should know the product it should be him/her. I know our NQ rep from BLA is very helpfull for all things humminbird.

Mate take a pi cof your transom from side on and from the rear and send those pics with the ones you have here to Lowrance.

The boys there can help you out and call beforehand and tell them you need help installing the transducers.

Should not be a problem and I have mine mounted totally different to yours but hten again mine is on a different type of boat.

You will get it sorted 100% sure.

Grouse is right about the 2D transduced obstructing your structure scan. You might also need to consider whether the outboard leg and prop will interfere with the structure scan transducer when it is trimed down in your normal driving position. Doesn't look like an easy one with the strakes and positioning I suggest you get a pro to have a look, do some on water runs and adjust until you get it just how you want.

gday could you mount under the step?

i dont see why i couldnt just screw it straight to the step underneath it like a direct mount- whether that would be a good idea or nots another issue i guess

thanks leelee- i like your optimism and hope your right- you seem to be clued up on this stuff

is there an email address you have thast best to get them on, on their website there is only like one of those auto-fill form things that i can find and no option for adding attachments......

Mate best to give them a call and get one of their emails and send it to them whilst you are on the phone and get them to have a look at it right there and then. Best to ring early in the day as well. As soon as they open the lines.

I have had emails sent to me directly from Lowrance when I have been on the phone with them regarding networking issues.

The side scan unit you have also in its current position should not interfere with the 2d transducer because they are designed to work in very close proximity but cannot say there will be no interference from motor when trimmed down. Hard to see via the pics but the Lowrance guys should be able to figure that one out for you.
