Side and Down Image Screen Shot – Bottom Composition

In this series of Side Image and Down Image scans on my Blog I’m trying and teach you what you are looking at while scanning with your Side Image and Down Image. This one will be of bottom composition.

If you notice the dark color in the screen shot is a mud or muck bottom. The sonar signal is absorbed in the soft material where the hard bottom in this case gravel and rock is hard and the sonar signal returns very quickly thus a brighter color on your screen.

Hope this helps you understand units.

Humminbird – Side Imaging – Flats

I started a series of Side Image and Down Image scans on my Blog to try and teach you what you should be looking for while scanning with your Side Image and Down Image. This one will be of a Flat in the back of a major creek. Hope this help your understand these expensive units.

Flat

Take a look at this photo before you scan down to the image below and see what you can find in this Side Image screen shot.

This screen shot side image was scanned in the fall of the year and as you can see there is a lot to be found in the image.

 

As you can see there is a lot to be seen in this photo look at the colored circles to see what is inside them.

Hope you find these photos useful.

Humminbird Down Image – Stumps, Piers and Bass

In this screen shot from my Humminbird Onix I did a Down Image of a pier along a deep cove. In the photo you can clearly see the pier post, a couple of stumps and bass suspended under the pier and  few bluegill hugging the bottom. When I scan using my Down Image I always use the 800 kHz settings to get a clearer detail image then I get with the 455 kHz setting.

Riverton Lock Construction

I had a chance to get out on Pickwick Lake yesterday and do a little fishing and side image recording with my Humminbird Onix 10 SI Cross Touch. While i was scanning in the back of Bear Creek I scanned these old railroad tracks. These tracks are part of the construction of the old canal system that starts t the mouth of First Creek on Wheeler Lake and runs all the way to Waterloo, Alabama. If you want to scan the tracks for yourself I posted the GPS coordinates on the photo.

You can see the train the used the tracks now located under Pickwick Lake.

Here is a drawing of the canal lock that is submerged under Pickwick Lake that is across the river from Waterloo.

Construction of the Riverton canal, as you can see there was a lot of manual labor involved in the construction.

Setting the stones used in the construction of the lock. Most of the stones were cut from quarries up and down the Tennessee River. Keller quarry was one such place and you can still see some of the cut stones located there to this day.

Stones set in place as part of the Riverton canal.

If you want to take a look at the lock with your Side and down Image units here is the GPS coordinates: N34.53.851 – W088.04.048 enjoy.

Side Image Scanning- Old Car or Truck Frame Found

I like to record from my Side Image and Down Image units as I’m fishing. I usually try to spend the last 15 minutes or so of my day on the water recording what my units is scanning. If you don’t know how to do this there are a few older blogs on this site that will show you what you need and how to do it. Just do a search for RECORDING from the search bar on the right side of the screen.

As it was recording yesterday I found this old auto frame in Pickwick Lake. To me it looks like the frame might be the only thing left. Since it is upside down I can’t tell if it’s a truck or car frame. I’ll try to get a better image of it the next time I’m in the area. If you would like to take a look at it here are the GPS coordinates: N 34 46.333 – W087 42.199

Humminbird 455 kHz vs 800 kHz Settings

Here are two more screen shoots that i did from a recording from my Humminbird Onix 10 SI Cross Touch unit. As you can see from the first screen shot there is a school of bait fish and to the right there is a small top or stump. Can you spot the top and the possible fish in that area?

Humminbird unit down image set to 455 kHz settings.

Down image set to 800 kHz setting.

Now let’s look at another screen shoot from the same area but this time I have the 800 kHz settings instead of the 455 kHz. Can you see the treetop and or stumps from the first screenshot? As you can see there is a huge difference when you are looking for structure and fish while scanning with your down image unit.
