I have a HDS 5 and recently bought the LSS-1 (and another HDS 5 I found used for a good deal). Got it on a Wednesday, installed it Thursday with plans to test it out Friday. I have been reading about installing one of these for a while as I knew I wanted one, so was hoping it would go smoothly.
First thing to install of course was the transducer. I have a fiberglass fish & ski and was doing a transom mount so was not hard to find a place to put it - about 6-7" to the left of the regular transducer.
At first I just "eyeballed" it in position and it looked pretty good to me, but then I got a level to check it out and was a good thing I did. Probably because of the angle of the hull, but eyeballing level was a good inch or so from true level.
Then I put the LSS-1 under the dash and wire it all up. Couldn't wait to get to the lake the next day.
Got to the lake, all excited, launched the boat, parked my truck and came back down to play. Turned on the HDS and.......nothing. Said no source. Bummer. Spent a few minutes checking out my wiring when it dawned on me - I never turned the LSS-1 on - not used to flipping the extra switch.
So with trepidation, I hit the switch.
I have been reading everything i could find on these for the last few months and I have come across a whole bunch of people posting about how the images on theirs was not at all like what they were seeing others posting- basically pretty much like the normal 2d sonar or also more then a couple people talking about how their side scan would only read out around 60' or so.
With all these things bouncing around my head I had already figured i was going to be spending a couple of hours playing with the setting and then the picture started filling in from right to left.
I started off with the down scan imaging and it looked pretty good to me as it was. Trolling out of the no wake zone , I could now see the small trees in the water that I always thought was fish with the 2d.
Flipped on the down scan and much to my delight - was about perfect. The only thing i had to adjust at all was the contrast as it was a tad bright. Not only that, it was reading out 300' - so distance was no problem at all.
Spent all night zipping around the lake to places where I always saw fish but could never catch any - yep, sure enough it was usually trees down there. I'm sure an experienced user would have known, but i always thought it was fish.
It turned out to be everything i had hoped for and more - don't have to worry about interpreting anything as you can see what it is plain as day - even I can use this effectively :laugh:

I could be wrong and often am, but for those who are having problems, I would go back and check the transducer mount. Don't just eyeball it, it is big enough and easy enough to lay a level across it - I was using a 3 foot carpenter's level. Pretty sure if I would have just eyeballed it, since it was a couple of inches off I would have been on here asking what i could do to make my images better. The angle on the hull will make it seem level when it isn't - anyway, just a suggestion for those having problems and is easy enough to check.

I would get a pretty clear reading up to about 25mph, tho it was still easily read at 30, it just started getting pretty noisy.
I believe I also read where you have to be moving at least a little bit to get good side scan images - I was drifting, but the lake was really smooth so i was not drifting very fast at all yet I was still getting excellent images when I wasn't moving at all. just surprised me as I didn't think I would.

I ended up staying out until 4:30am playing with it, fortunately it was a really warm night and only got down to like 54. Did not fish nearly as much as I should have. This will surely have to help put fish in the boat.
I did have one problem and also one thing that was not so good.
The problem - I have a Motorguide W75 wireless trolling motor and it was on it's own set of batteries. I had the HDS 5 wired up to wires already in my dash and it worked fine before I added the LSS-1. I also wired the LSS-1 to wires already under there - which go to the main battery and i used the accessory switch in the dash to switch on the lss-1 - the only thing on the switch.
Couldn't run my trolling motor and the sonar at the same time - too much interference and the screen pretty much went all white - the only thing I could track was the depth. It also affected the 2D sonar. For some reason, tho there was still interference, if the trolling motor was on the highest speed, I could use the sonar.
So I guess my 1st plan of action will be to run wires to the LSS-1 directly to the main battery - seemed strange tho since the trolling motor is on it's own set of batteries.

The one not so good thing - down imaging is fine, but for the side scan, the 5" screen is just too small. Way too much info on too small a screen. I had it on auto distance and it was shooting out 200-300' all of the time so a few times I was setting it manually for 60-80' depending on what i was trying to read. Also if I wanted to read the shore line, I would set it for right side or left side only. It was working great, but if anyone ever asked me, if there was anyway you could possibly afford it, I would definitely suggest the 8" screen as the minimum and I can see how the 10" would be the one to get. Pricey yes, but now I can see how it would be worth it.
I did pick up another HDS 5, used for like $360.00, but i want to mount it in the bow with it's own transducer and then I can switch between transducers for whatever is best for the situation. Even if I mounted it beside the other one, it is still a 5" screen so the side scan is not going to look any bigger.
With the size of the screen, I do not see me using a split screen for s.i. and d.i. Not knowing much yet, I would guess the side imaging is going to be more important to me and if I see something i want to take a 2nd look at, I can go back over it with the down imaging.
point being - if there is anyway you can swing it, get the bigger screens.

I was expecting this to be something I would have to end up playing around with the settings and never get as good of images as I have seen people post of their screen captures. instead, within minutes on the water without touching a thing, I was looking at a submerged tree that was as clear as day and was more like i was looking at an underwater camera.

Worth every penny.
Now I won't have to waste as much dynamite looking for the fish
 
I would run wires straight to cranking batteries, it solved alot of issues with my hd7s, and I used the yellow wake up wire on LSS and connected it to the hd7 at console. It powers on and off when you power up the unit.
 
thanks for the info, is the game plan, hopefully get to it tomorrow. Got the other HDS 5 today so will need to run some wires up to the bow for that. Not sure, but was reading up on interference and came across some info talking about how running a ground wire from the main battery to the trolling motor batteries can help with conductive interference - if the straight wires thru don't work, will try that
 
Hey Bronzeback how are you? Hey I am looking at getting an HDS7 myself, how do you like yours? I will end up buying the Side Scan later but want to go ahead and get the 7 on the boat. Should I go for a base unit and buy my own insight card or just get the unit with the insight already in it?

Thanks
 
Don, thanks for all the info. I am going to be adding a HSD7 since I too have a HDS5x, and the with any luck a side scan box sometime before summer. Reading your post makes me feel much better about going with a 7 instead of another 5, and getting the whole side scan box too.. Great post with lots of good info.
 
bluewingjb - my opinion fwiw. I bought the one with the preloaded maps. Can't say I have even seen anything else, but I was really impressed by the preloaded ones. 1st was using it on Tims and it had every hazard like stump fields etc marked on it - even some in places I didn;t know about. I went to Woods and have never really been there in a boat. Good thing the maps were good - I was headed over to a bridge through what looked like the main part of the lake to me. Maps showed it as a hazard - low water and a big stump field to the right and it was spot on.
Depth has also been spot on for me so far.
Has some black triangles on the screen that I didn't know what they meant, so cruised over the area with the sonar - has all of the springs marked on it already.
I personally don;t see how a different map would be any better unless it had all of the structure on the bottom already mapped out for me - but then I wouldn't need the structurescan
 
it has every inland lake - or so it says and i have no reason to doubt it. Because there are like 10,000 maps, is why I was surprised how good it was, especially for Woods. i can see Tims as that is a pretty popular destination, but Woods was marked just as good.
No, it is not 3D. For 3D I believe you have to buy those maps. Never had it so maybe i am wrong, but now that I have structurescan, I am not sure 3d would really add that much to me catching fish - tho I am a novice at using charts this way.
 
The Lake Insight models are generally not but $100 more than the base models and well worth the money. Just the East card by itself is $100. If you can swing the Insight/LSS-1 bundle you save about $200 on the LSS-1.
