(March 2008)

This album is available to the public to view.  All I ask in return is that you sign the guestbook and let me know how you ended up here...

This is basically a ongoing tutorial explaining my experience/learning curve with Humminbird Side imaging technology, starting with my initial purchase of a 997 in 2008.  I have since moved to 1100 series units, with a trolling motor application for Side Imaging also, starting with pictures 110-118 on how to rig the transducer to the Terrova.  2015: I now run and Onix 10 at the console so you will see some different screen options, and recently upgrade my bow unit to a H12 SI.

While 2-3 mph may be optimum viewing speed, you can  see fish at .01 and as high as 10 mph in Side Imaging.I try experiment and learn something new every trip out with my equipment.  If you are ever going to get good  with your equipment, you need to use it.

The key to getting good results, is to take the time to properly set up your transducer in the beginning.  This will pay dividends down the road..  You cannot expect high performance out of your unit, if your transducer installation is not up to speed.

Please sign the guestbook!

Fast water below dam, slightly below the 400 ft restriction. Note the swirl effect on the bottom right. This is the remains of a turn I needed to do to get straight. Side imaging, needs to be done in as  straight of a line as possible, or the screen distorts the picture.  When turning the side imaging, its alot like running plugs on a turn, the outside one runs faster, while the inside one slows down. Same thing with side imagery.

Here is a great picture of 9 walleyes on the left and 4 on the right.  Take note of the distance the shadow is behind the fish. This is a function of how high the fish is off the bottom. Note the appearance of the shadow of the fish on the right side across from the date.  The shapes of these two fish are definitely walleyes.  This is the screencapture that totally changed how I used SI.

Here is a series of 3 consecutive pictures, all taken within about 4 boat lengths. Note the depth,rough texture on the right side and the smooth bottom texture in the left.

Here is a slow speed, (stationary boat) snapshot of a small school of eyes off to the right side of the boat. The only fish that leaves a good "shadow" is the fish that probably is swimming thru the beam at a faster pace, hence a better scan(shadow) of it.  The other fish are stationary and leave a long, drawn out image.

The following series of pictures will show how to mount a HDSI 180T side imaging transducer to a MinnKota Terrova with a slick approach to the cabling issue.  This picture shows the IPilot head removed and the three wires diconnected for removal of the head.

Enlarge photo 111
Slide the shaft back into the steering assembly.

Enlarge photo 112
Thread the drive collet onto the shaft with all 5 cables.

Enlarge photo 113
I then took dabs of silicone caulk and attached the cable in about 6 spots going up the shaft. I taped them with electrical tape, and left it overnight.

Enlarge photo 114
Mount the head back onto the unit like it was before. Wire tie the cable to the top of the shaft and thread it back down the coiled cord feeding the Terrova power, which will place it near the Humminbird unit when in use. I also have a Ram mount assembly to tie the shaft down when trailering or rough water.

Here is my first attempt at setting my unit up for verticle jigging.  You can clearly see the jig in both types of sonar, 2D (83/200 khz combo) and Down Imaging.  Because the 2D sonar cone is larger, the fish (big red arc) shows up well in DI also.  Because of the small beam of DI, it is hard to get the jig to show up, as it has to be in near perfect position to print out.
I was pretty impressed with this application.  Enough to make me go deeper more often... Not a chance!

Enlarge photo 127
Here is a combination shot of 2D and Down imaging.  There is considerable difference in what a fish looks like between the two options.  On the DI screen the white vertical lines are when my trolling motor was running, and the clear area is where it was shut off.  I'm ok with a little interference, as long as I can see thru it.

Enlarge photo 128
Here is another 2D/Di image where you see the jig (1/4 oz) fading in and out of the DI screen. On the 2D side,you can see where I set the hook on a fish and missed it(above the 6 in 36.9) and then settled the jig back down on the right.

Rollie you have some great looking images from your 997.  Haven't had a chance to look at all of them yet, but I'll get to them.  Thanks for the invite over.

Thanks Rollie for you help. After running lowrance products for 20 yrs, you made the switch an even easier decision.  I'm buying a humminbird.

Can you please email or call me about your Humminbird unit we are very frustrated trying to get the settings correct. I would really appreciate it. Thanks Ethan  585-703-4832

Great shots and very good info....As a new SI owner, I am always looking for good info..

Great pic.  #88 is of real interest.  I must have my transducer mounted wrong as it sits at the same angle as you speedo How did you arrive at that angle and what is the brown material.  I don't believe I'm getting as good of a signal as you show.  Any help would be great.  I have a 997 mounted on a 1900 Pro V.  Love em both.  Thanks

Man you have some awesome images! I love Image #24! That truely shows the power of Humminbird Side Imaging versus any 2D sonar. If others want to learn more I recommend joining the Side Imaging Group:

Great Pictures, i just purchased a 797 and i love it. i get awesome pictures of humps, creeks etc.. Im not really seeing the fish like you do, but the lake im on is packed with structure, do you have to make ant special changes to see fish? or do you figure all this structure is covering up the fish. I would like to send you some of my shots if i could?

Thanks for showing me the side scan sonar!!! Just ordered the 1197c SAR model for search and rescue operations for the Lower Brule Sioux Tribe. Great images!! Thanks again
