When scanning the lake bottom with your Side Image unit regardless of what brand or model you have to get the best images requires the correct angle you scan from. In the images below I have images of a side scan with a Humminbird unit at different angles to show you what I mean.
In the image above the boat is on the right side of my boat and I’m heading up river. And as you see that I almost ran over the top of the boat by looking at the top left corner of the boat with my boat.
In the image above you can see that I took my boat over the very top of the sunken boat with part of the boat on the right and the left sides of the scan. By the way can you see the Bluegill beds in the sunken boat.
In the above image you can see I got the correct angle of the sunken boat and you can see the entire boat and the details of the boat.
Look at the above image and you can see I got the angle wrong.
Here I have the boat and chart speed wrong for the best scanning image.
Now in this image you can see it all came together with the correct boat speed, correct chart speed and the correct angle. I’m on the inside shallow side of the boat scanning up river at a slight angle to the boat to get the best scan of the boat.
So the next time you are on your lake and spot something, try scanning it from different angle and speeds to get the very best image of what you are looking at. This all takes time on the water with your unitsand playing with the settings.
In my last blog I showed you a software program I used on
how I manage my waypoints and allows me to see where they are along with the
contour lines on a lake map. But as you may have noticed the contour lines were
listed in “Meters” instead of feet. But you are able to change it to feet if
you prefer to use them instead. You will need to be a little computer savvy to
make this change but you should be able to do it by following the following
First thing is to make sure the SAS Planet program is
closed. Now you will need to find the “Folder” where you installed the program.
Next, we need to “Open” the folder by double clicking on the folder. After you have the folder open you will now need to open the next folder. This will be labeled as “Maps” double click on this folder.
The next folder we need to open is the”_water”” folder. Move your mouse over the folder and double click to open the folder.
Then next folder that we need tot open is the “SAS.plus.maps” folder. Double click on this folder to open it.
Now we need to open the “navionics.layer.zmp” folder to make the changes required to change the meters to feet settings.
Now inside this folder you will find a file by the name of “GetUrlScript.txt” this is the text file we need to edit to change the program from “Meters” to “Feet”. Double click on the file and it will open in the Windows “Notepad” program.
Look at the line I have high-lighted and you will see a red circle with a number “1” in it. To make the change all we have to do is change the “1” to a “2”.
After you edit the number all we need to do is “Save” the file. DO NOT rename the file or “Save As” or move the file! Just select “Save” and close the “Notepad” program. See photo below.
Now that you have made the change to that file, we need to do the same thing to three more files. Just repeat the same steps in the three following folders.
After you have edited all four files then you can open the
SASPlanet program and you should see the depth contour lines are now in “Feet”
and not “Meters”.
Hope you enjoy the SAS Planet program as I do in managing
all your hundreds or thousands of waypoints.
Do you want to get the most out of your GPS units and
managing all your way points as I do? If you have thousands of way points and
have a hard time keeping them organized then you should take a look at
downloading a software program which is free by the way called “SASPlanet” or type in this link in
your browser where you can download the software. (http://www.sasgis.org/download/)
As of this blog the latest version released is 181221 but
they are continually releasing newer version but this is the one that I
personally use. Notice at the top of the web page that you will need to change
the translation from Russian to English. In the second red oval in the photo is
the link to download the software. By way you do NOT have to provide any
personal information to download the software.
From the download link just download and make sure you know
your download files location which is usually the “Download” folder on your
After you have downloaded the software you will need to
un-compress the file as it is in “.zip” format which should already be on your
computer. If not you should be able to find it on the web with a browser search
Now that you have downloaded and installed the software let
me show you how helpful it will be to you. When you first launch the software
program a screen should pop up similar to this one, if not just move your mouse
around and zoom in or out to your area or lake you fish.
In the photo below I have zoomed in and selected a lake at
random which I’ll use in this blog, at the present time I do not know where or
what lake this is. But as this is only an example you can simply zoom in on
your lake that you fish or want information about. Now we need to make a few
adjustments in the setting of the software.
When you zoom in on the map you should get a view like the
one below. But we need to change it since we want to use it for our GPS way
Now let’s make the necessary adjustments to may the software
do what we want to use it for. How we do this is to make a change in the type
of map we want to use. On the Menu bar you should see the option to change the
map as shown in the photo below. From the drop-down maps options you want to
select “Marine maps”, then select “Navionics Marine Charts” do not select
Now as you can see in the photo below the background as well
as the water has now changed to a map with depth contour lines. NOTE: The
depths are shown as “Meters” and not “Feet” in another blog I’ll show you how
to change the meters to feet settings.
Now if you Zoom in on the map you can see the contour lines
for the lake and areas of the lake you want to explore.
Now let’s play around with the map and create a few way
points by just looking at the map of the lake as we move around it. Okay let’s
say we see a spot we would like to create a way point on, then do the following
as in the photo below.
You can place your mouse cursor over say a point, hump, flat
and anywhere you want a way point. Select “Add Placemark” And once you do the
following menu box will pop up allowing you to make some adjustments to the waypoint
you will create.
Under the “Category” I rename this to the Lake or area of
the lake I want the way points on. Next under “Name” give the waypoint a name
up to eleven letters or numbers. (Any more than eleven you will get an error
message when you try to convert them in Humminbird PC). Under the “Geographic
Coordinates” you can make changes if necessary. In a few paragraph’s I’ll show
you how to change the coordinates types that we normally will use in our units.
Next under the “Descriptions” box you can write notes applying to the waypoints.
On the “Text color” option I select “Red” as it shows up better on the map
background. After you make these changes hit the “OK” button.
After you hit “OK” the next box that will pop up will be the
“Placement Manager” menu. Here you will see the Category and list of waypoints
you created. But you will have the option to Import your current way points or
share them from or with your buddies.
Okay let’s say we have way points that we want to “Edit”
your way points. Select the Way point from the list and we can make those edits,
lake name, way point name, coordinates and notes as we notes above.
Here you see I make the edits I wanted for this waypoint. Note: These are fictious way points as I have never fished Broken Bow and the notes are for example only.
Next I’ll show you how to change the coordinates to the type we normally use. Across the top Menu bar select “Settings” then “Options”.
From the Menu taps select “View” and the select the
drop-down options on the way point coordinates types.
Select the one I have the arrow on or “WS deg.min.” This
option will add an extra number on the last number for example “1234” just
change the “4” to a “0” so it will look like “1230”.
After you have finished editing or creating your waypoints
you now have the option to export them to a “GPX” file which you can convert
them to any “GPS” coordinates you need. You can convert them in Humminbird PC
to work in your Helix, Onyx or Solix units. You can convert them to use in
Lowrance or Garmin units with GPS Babel for example. You export them by selecting the “Category”
name the press your Right Mouse button. The Export Placemarks menu will pop up.
The program will try to save them as a “.kmz” format but you
need to select the drop-down menu and select “.gpx” instead.
Now let me show you how to “Import” your current waypoints you
may already have. If they are on your unit or units you will need to get them
on an SD card and then copy them to your computer. If they are from Helix,
Garmin or Lowrance units you can convert them to “GPX” format with Humminbird
PC. From the “Operations” Menu select “Open” and then you will be prompted for
the waypoint file location which could be the SD card if they are in “GPX”
Select the waypoint file and select “Open” to import them
into the program.
Note if you already have the “Placemark Manager” open you
can “Import” them by selecting the “Import” button at the bottom right on the
When you select the “Open” then the file you will get the following
menu options in the photo below. Here you can rename the waypoint file to
anything you want. For an example let’s say you have two units on your boat and
have waypoints on both of them that are not linked. Save one file as say “Rear
Unit” and the other one as “Bow Unit”. That way you know which waypoints are on
which unit. You can compare the waypoints on both units and add or delete the
ones that are duplicates, bad ones, old ones or anything else you might want to
do with them. One thing I do is change the “Icons” for each file so I know
which file is on which unit. When finished with your “Edits” select “Start” on
After you make your edits and select “Start” the next screen
will look like this now just select “Yes” to import the waypoints.
Now to see the waypoints you imported you must select the “Placemark
Manager”. In the top menu bar select it, the one in the red circle in the photo
Now we can view our waypoints by placing a “Check” mark in
the “Categories” waypoint list.
Now you can see all your waypoints on the map.
Hope you found this helpful and hope this helps you manage
all your waypoints.
Do you fish braided line with a monofilament or fluorocarbon leader? The Albright Knot is one of the best for this but to me was a hard knot to tie. I made a simple jig for tying this knot that I keep in my boat. You can make your own jig or modify it anyway you want to but this one works great for me and is very simple to make. Here is a video of the jig and how I tie the Albright Knot.
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
