|Albertan||It took me a little longer to move these around, as I was waiting for the extension cables for the SS3D which were on backorder. It looks like I will now need an extension for the HDI as well. I decided to re-route the transducer cables under the port side gunnel instead of the starboard side. The starboard side has a bundle of wires around 2" in diameter, including power wires. The port side has nothing but two speaker wires. Hopefully that can help reduce any chance of interference as well. Anyways, I've attached some pictures of the new mounting. Hopefully no one sees any potential issues. I still have to finalize the position of the 'ducers on the water. But I think both should be fairly close now. Thanks.|

I think there are some setups that go against general recommendations with good results, and some setups where maybe people's results aren't great but they are not even aware it could be better. I'm trying to follow Lowrance's recommendations, augmented by feedback from experienced users, to get the best results when open water arrives in a couple of months. Then it's just tweaking from there.

I haven't had the chance to use Fish Reveal yet, but I'm looking forward to it. Since the HDI has 2D and downscan, I don't have to worry about how close together the transducers are anyways in my application.

|ltrain||Hey Albertan, I think you'd be best mounting your transducers on the opposite side of your kicker motor. Think that kicker will interfere with your side scan and the prop wash from it with your 2d when you are trolling. I had a Tyee with a kicker on the starboard side and put my transducers on the port side and they did fine. As you already figured that strake will mess with you at speed too so try to avoid the strake on the port side too.|

I'm probably an outlier here, but I've never worried about keeping the transducers close to each other. I've got the down/side imaging on one side of the motor and the 2D on the other.
The fish reveal works fine. Maybe the fish are not shown exactly where they actually are displayed on the screen, but so what? All I want to know is, could there be fish present that I can't see on the 2D 'ducer? Where they are exactly just isn't important to me. If the electronics thinks fish may or may not be there I'll fish for them, if not I'll keep moving/looking.
Fish reveal can be a game changer. How many times have we not marked any fish on the 2D, but catch one fish and suddenly the screen is full of fish suddenly interested in the commotion. Those fish were belly on the bottom, in the rocks and invisible to the 2D. The Fish reveal has made me more confident that there might be or probably are fish there. So I tend to give that spot a slightly longer look before moving on.
Besides that, I didn't have a clear place to locate both transducers next to each other avoiding stringers and props...

|Albertan||Yeah, I did that Pooch when I mounted the SS3D transducer. Like I said, I have that one about where I wanted it height-wise. The HDI is just mounted in the holes from the old skimmer to mock it up and that's as high as it will go. I didn't want to drill new holes because I thought right off the bat I was going to have a problem with that strake where it was. Nothing another $150 in extension cables for the SS3D won't fix. lol.|

Lay a straight edge along the bottom of the hull to get an idea of where the water flow will cross the the transducer. I run mine just deep enough to get a signal at speed without throwing any rooster tail. Good place to start then tweak it on the water.
Besides height of the 'ducer, pitch forward and aft can make a big difference. Keep in mind that the overall angle of the boat changes on plane. Getting that right is usually the hardest part for me.
Nice job of mounting. That stringer might be a problem?

|Albertan||Thanks for your feedback. You're not the first person to express some concern about that strake. I think I am going to move the SS3D over to the same location on the port ducer board, and move the HDI down to where the SS3D is currently to get it away from that strake. Since the HDI has downscan and 2D, I don't need to worry about having both transducers close together for downscan overlay/fish reveal (took a moment for that to click). And I won't be going too fast when using the SS3D ducer, so prop wash on the port side shouldn't be an issue as best I can tell. Lots of on the water testing to follow for sure. I'm just trying to "get it on the paper" for Spring.|

It looks pretty good to me.
I'd say the SS3D is pretty much bang on where you want it height wise, you might have to experiment a bit with the tilt angle. You'll likely have to trim up the big motor a bit to get full sonar coverage on the port side.
I'd say your HDI is mounted a little low right now, I think you'll have a pretty big rooster tail and a lot of drag. I can see why you did it to try and compensate for the strake. I'm not sure how that strake will affect things, it might cause some problems, but with where the HDI is placed now, you might be OK. Without the strake, I'd say you could move it up almost a 1/4", maybe even a bit more and still be OK. At any rate, I think you're at a good starting point, but I'd expect to have to do a little trial and error to get it dialed in perfectly. It wouldn't really surprise me if you had to add another transducer board and move the HDI away from that strake and over in line with your other bunk to get a really good 2D signal at speed. I don't think that would cause you too much grief in terms of your 2D overlay or Fish Reveal, you'd still be within about 12-14" by the look of it.
