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.

Humminbird Auto Chart Pro Overlays

If you own a Humminbird unit and their Auto Chart Pro software then you will be able to see what you’re fishing as you are on the water from your waypoints. Not only will you be able to see the contour lines but also what is on the bottom of the lake ahead of you, behind you and to the right and the left of you as you’re on the water fishing. Mark a waypoint and pull up onto it and start making your cast thinking you hit might that stump, brush pile or rock pile? With the Auto Chart Pro software you will be able to know what it is that you are casting to. If you have your units hooked to a network the Overlays will show up on the other unit even if you don’t have a Zero Line card in that unit. I have mine in the console unit and it shows on my bow unit as I’m fishing my waypoints.










(Figure 1)

On a standard GPS screen you only see the contour lines and your waypoint icon. (The red lines are my track).

Now take a look at that same GPS screen with the Auto Chart Pro software with the Side Image Mosaic recording overlay. Make sure you have your Auto Chart Pro Zero Lines Card in the second SD card slot.

(Figure 2)

See the huge difference in knowing what you are casting to?










(Figure 3)

See the huge rock that you can clearly see? You can now see where the target is at know exactly where to make your cast.

I did a prior blog on the Software and how to do Recordings and converting them into a Side Image Mosaic.

Okay now that we have the converted maps and recording on your Auto Chart Zero Lines Card here are the settings you will need to make to get them on the screen. These Menu settings are on my Onix 10 SI Cross Touch. Select the GPS screen on the unit and select the Menu button on the unit to bring up the menu options for the GPS screen.

Scroll down to the bottom option and select Chart Options.







(Figure AC_3a)

After selecting Chart Options now Select Map Data. As you can see I have Global turned OFF for these settings.







(Figure AC_9a)               (Figure AC_4a)

The first thing we need to do is to select Satellite–Land from the Base Layer option menus screen. This let’s you see both the contour lines and the satellite image of the land around the lake. Press Exit once to go back to the prior screen.







(Figure AC_5a)

Now from the Map Data menu screen select Map Overlay for the next options.







(Figure AC_6a)

Make sure that Overlays is turned ON and I like mine set at 90%. Also select SI Mosaic option as well. Press the Exit button once to go back to the prior screen.







(Figure AC_7a)

From the Map Data menu screen this time select Depth so you can make a few option selections there.







(Figure AC_8a)

Make sure to select Depth Colors is ON I use 5 colors. Make sure Depth Highlight is ON, I set the mine to 1 foot. The last thing is to set your Highlight Range. I use 5 feet for mine. That’s it now exit ll the way out to the GPS map screen again.










Hope this help you more out of your Humminbird units.
