    Default How-to topics and FAQ about Capturing, Posting and Interpreting Images

    Noticed yesterday when a buddy and I fished together. He has ran a SI unit longer than me but runs a Low unit and watching him led me to getting one. He knows his unit very well. He was asking about structure that I was marking and pointing out. I didnt under stand how this didn't just pop out to him once he saw it. It's all in what you are used too and makes me see the Q's that pop up about interpretation of SI for a new user in a new light.

    I went through the same learning curve as us all but will try to be more detailed in helping others if I can when these Q come up.

    Was thinking about posting shots that shows the bottom and how we read them to help us find fish and structure. A shot like this with markings depicting what we are looking at.





    I can then add info as to what I see as in this shot. This will not only help others just starting but helps me in case I'm reading it wrong so we can learn the unit better.





    Just a thought but wanted to see if others would be interested. let me know

    This is two shots of a bamboo bucket structure. A bundle of bamboo in a bucket full of concrete.

    In the first shot you can see the fish stacked around the bamboo structure, at the tip of the tree to the left and some just scattered out. Due to several passes in the area you can also see the prop wash trail or what looks like a cloud, the trail shows up good to the far left. The more you go through an area the worst it will get.





    This is the same type structure just down the lake without the fish seen in the first shot. In this shot you can see what happens if you dont raise the motor enough by the interference just left of center.





    What other structure do you see?

    By doing a quick search you cut down on unproductive water. Making a pass with sharpness off will help see crisp shots to lead you to structure to look at closer. Turning the sharpness to low will bring out the fish better but the shot will be grainy looking.

    In this shot I was in 455 when I found it. Due to the depth I changed over to 800 and could see better detail than I did 455. When I changed to 800 I had to tweak the Sen. and Contrast some to get a shot that looked good to me. Settings from what I've seen on different lakes, bottom type and depth can change a lot from one user to the next. Basic settings will get the job done but to get the most out of your unit try different things. Have what works best written down...you can always go back to it. If it really gets bad there is always default.

    From left to right you can see a small ledge or drop just left of the next mark being a road bed. A waypoint was placed due to the standing timber holding fish. Notice that the standing timber numbers do not match up to the amount of shadows you can see on the lake bottom going away from the boat. Use the inter screen to interpret what is being seen. This deep structure is what I want to fish in winter or the heat of summer. Also marked is a cloud of bait.

    Based off the right of the screen, what three things stand out or what information is it giving you?

    The shots that are being posted are intended to help new users as well as myself and others get the best image from their units. I ask that if you see a screen shot and have had a similar case, to post what have you have done to make it better or explain what you see as others have done on past post.

    Please don't take these as a "I know it all" type post, that is not my intent. It's done to better help us both learn.
    -----------------------------------------------------------

    These shots are posted to show how changes in Sen. and Contrast can make a large change in the image to better give detail to what we are going past. With the changes you can see better shadowing and crisper edges start to appear. One group of settings I find is not the best for all parts of the lake..it may show a picture but I find it could always be better with some fine tuning.









    In the 2nd shot I take the bright cloud to the upper right of the temp as that bait cloud or group of fish moving away from the boat. Does this sound or look right?

    Note: this post was copied from http://www.crappie.com/crappie/side-...ot-deep-gills/ where you may find more discussion.


    Went out this morning to try and find some deep water gills. While they are bedding it's not a problem but after they come off bed I'm used to catching dinks. After reading how they move out deep off gravel or rocky points I picked out several points that dropped off deep. Due to wanting to see hard bottom mixed in with the mud I changes over to red/green pallet. This was the 3rd point I looked at and the red was not located in the other two locations.

    I would run my pass while making a recording then pull off and review the spot. (Greg! your the man!!! worked great!) In this location I finally saw red indicating hard bottom.





    I then changed over to my normal blue pallet but was not seeing what I thought should be there.






    As I went through the pallets I came to brown and was getting better.







    I then went from sharpness off to sharpness on and could tell the point was holding fish. Notice in the red/green shot the long shelf of gravel. The top of the point in this shot is more of dots which I took as fish. The shelf was more of a blur. Now to see if what I was looking at was what we were after.







    The wife and I went back and dropped a marker over the right group of fish and never left that spot. We used a drop shot rig with crickets and hooked one after the other. Great day with the better half and a new spot to boot.

    Hope this info helps someone.

    These shots were taken over a large mud flat to show how just a slight adjustment of the motor can effect SI on the motor side.






    Up to the yellow line you can see the mud flat left and right. (A)To the left or motor side you can then see the interference from adjusting the motor down a bit and once stopped I then have dead space where the motor is blocking some of the SI signal. (B) You can also see where a interference line shows up to the left. The signal is hitting the motor.







    Once the motor is angled back up the interference line goes away and the bottom returns.


    Dark areas in the SI view can be made from other things as well. A sloping bottom, shadows from large humps or the other side of a point could give this darker image. A muddy bottom with low Sen. setting could be dark but raising the Sen. will start to bring detail out.

    If you notice that this happening on the motor side try to raise the motor some and see if this helps clear up the image.

    Sorry so long but finding what your looking for and fish that will cooperate is two different things.

    Finding ledges with a shelf near deep water this time of year that have structure near by can produce some nice size fish compared to those shallower it seems. Fishing both fall downs and ledges today my bigger fish came off the ledges.

    First look at your map and find those locations where the contour lines come together but have a spread on one end. Using this shot as a guide only (the location I was fishing has tracks and waypoints blocking the lines) you can see how they come close and then to the right is a shelf. That would be a good place to drop structure and depending on the time of year pull in fish to hold.





    When you find several of these locations go out and run them and make a recording. I find that running the ledge at a angle will give better shadowing and pop out better. After running I then play it back and make my changes to fine tune the shot to give the image that looks best to me. No ones settings will be the same due to preferences and body of water I've found.









    Above as I went through different pallets I found that Brown showed better detail (for me) as shown below. Here you can see the ledge and how it runs. By adjusting the Sen. and Contrast and using sharpness you will get a better idea if you want to fish it or not.





    You can also use one side to get better detail as far as inlarging the area you are interested in.





    In those shots I was finding the ledge but no structure to hold fish. Running a few more passes with the new settings and once again making a recording I found that just up screen from these shots was what I thought to be a brush drop on the edge. After checking the recording I saw that it was holding fish.













    Knowing the depth the fish started at I was able to cast past the structure in shallower water, count down and run just over and to the sides to pull in some fish. It may seem like it's time consuming but it really cuts down on the guess work. Hope something in here helps you out. Good luck









    (working on a post that deals with fishing fall downs but after leaving that location and seeing what the two were producing it may be a minute....hard to leave the big ones ​ )
