Your pixel resolution in side-display mode may not support such fine detail on a shadow, which is nothing more than a software-generated light rendering product. However your down display mode can support such finer resolution. When I look at the photo you posted, I can see the faint traces of the thickest sections of the shadow you are referring to. Data is data and its all collected one time. You can process it a thousand ways but you're not going to change the captured data.
Its not an inverted SI pic. I already posted how they do it. Have good T-giving!

The problem with these units and deep water is motional stability due to sea surface conditions. Real sidescans are towfishes and not transom-fixed transducers for this very reason: they are less susceptible to motionally induced errors in image processing due to being submerged under general wave action, and they also have increased range and power by running at deeper depths, removing loss from the majority of the water column.
Until someone is smart enough to focus on software processing to decouple motional errors from the image product, fluff like the "down imaging" will be the best you can expect as far as improvements go.
The challenge for these companies to technically compete with the real sidescan providers will be: 1) implementing motional error correction and image stabilization processing, and 2) increasing range and resolution for deep water performance. As far as cost competition, they've already won IMO. The bang for the buck of what either Lowrance or Humminbird offers is really impressive.
Agreed inlet...on the SI site and some other, there are posts on how to mount the HB SI ducer to a towfish.
The new free Down Imaging update has been out for a few weeks now. Here are a few real world pics i stole off of a different site. Looks pretty good!!

This image should clear up the "myth" about the dead spot. To get similar images on both sides you have to have full coverage. This is the same tree above just driven directly over the top.

I upgraded my unit last week. I can't wait to get on the water to take some readings of my own.

Do you use your boat in the winter or are you winterized??

I down loaded the new version of Down imaging on to my unit today. I will be on the lake tomorrow hopefully to get some live shots. Here are a few snap shots that i took off of my units simulator.....amazing. I hope it works as good as the simulator.

Pastaman, I was winterized. I pulled the cover a few weeks ago. Getting her ready for the season.

I've been comparing the Humminbird 998Si and the HDS8 and Side Scan for a while. Most of my fishing is fresh water but I go to the coast as often as I can and my fishing there is primarily inshore and bay systems with short range trips offshore, limited to about 10 miles off the beach on good days.
I see the Humminbird 998Si and the 998Si NVB systems for sale. The NVB has preloaded Navionics maps. Does anyone know what maps are preloaded? Is this a general load, maybe something like the Insight maps?
Pastaman, you seem to be in the know with Humminbird, do you know the answer? I've sent the question to Humminbird but have not received a reply yet.

I've always been impressed with the side imaging pictures. What the max depth you could expect in saltwater with the side imaging feature?
I have seen good pictures up till about 150'. I beleive thats the reccomended max depth. I dont fish that deep so i havent tried. There are some deeper saltwater pics that i posted on one of the other pages showing wrecks, etc!!

You can get the units with the NVB (navionics bundle) preloaded. You can pick either NVB Hotmaps for freshwater lakes of just NVB wich shows the saltwater coastline, bays and tributaries. I dont have the NVB dowload. I use (1) freshwater hotmaps card and saltwater card of the east coast from navionics.

First day on the water with the DI update. Im still in the learing phase and i wish i found some better sturcture but i think the pics are still decent. It was a good trial run!

Just came in the house for a break, installing my new 998c SI right now. Those images are cool. Did you get any of the fish? Looks like you just about hit one with the jig. LOL

Nope no fish. I was in a lake and those i think are land lock stripers but i coulndt get any to hit the jig. I had one come off on a rattle trap but he was only on for a couple of cranks. I didnt fish much.....just messing around with the electronics.

Pastaman,
You have a boat similar to mine (bay boat); I'm installing my 998c SI right now and wonder where the best place to mount the GPS puck might be. The readings for GPS Diagnostics are comparable wherever I move it on the boat. My console is full with a Garmin 545S and HB 998C SI side by side on the top shelf. I really would rather not mount it to the grab rail.
I'm thinking of the starboard aft corner, just right of the motor well. I have a swim step and ladder on the port aft corner.
Is your 997 internal GPS or external puck? Where did you mount yours if it is external and would you change that position if you had to do it again?
