Marking Waypoint With my Humminbird’s and Minn Kota Ultrex

I recently bought a Minn Kota Ultrex 112 / 36 volt trolling motor for my boat. Man talk about a game changer in my fishing experiences! Not only does it utilize the “Spot Lock” feature and the “Auto Pilot” feature it has changed the way I now mark and fish my waypoints while on the water.

Since I started doing “Recordings” with my Humminbird SI units several years ago, I now almost only mark structure that I’ve found on the lake bottom. This could be stumps, points, sunken treetops, old sunken boats or anything else I’ve found that could or does hold fish. I fish for both bass and crappie so marking sunken treetops really helps with my crappie fishing.

What I now do it view my recording on my home laptop from my last fishing trip to see if I have found anything that I need to take a better look at or to mark and fish. Take a look at the video below and you’ll see that I’m using the “ReefMaster Sonar Viewer” software that I’ve blogged about several time on this blog site. I do recommend that you spent the $49 dollars on this software and learn to use it. It will make a difference in how you view and use your Side Imaging.

Now that you have watched the video on how I mark my waypoints and my anchor spots here is an image of how I go to my waypoints. As you can see in the image there is a “Green” and a “Purple” heading line on the map screen. The “Green” line is from the internal “Course Up” heading from the Humminbird unit. And the “Purple” heading line is from the Humminbird AS GPS HS GPS Receiver (Precision GPS/WAAS receiver with Heading Sensor provides fast position fixes accurate within 2.5 meters or 8.2 feet.  Provides more accurate position fixes than the industry standard GPS.) which is an electronic heading compass. This compass sensor will cost you around $200 but in my opinion it is worth the extra expense.

The Purple line is the external GPS puck heading and the green line is from the internal GPS sensor in the unit. So you can see the accuracy of both of them.

To go to my waypoint that I want to fish I just line up the “Purple” line with the “AnchorTop” waypoint and the “TreeTop” waypoint and when I get to the “AnchorTop” waypoint the treetop is straight in front of the nose of the boat at either 40 or 50 feet. Hit your “Spot Lock” on the Ultrex and make you cast to the treetop. I also use the “Casting Rings” on all my waypoints so that I can make my cast to the waypoint from different angles is I want to.

As for fishing the waypoints I try to get the best angle on the structure as I can to get the best coverage for my cast. Here is an example of what I mean by this. Let’s look at all four angles in the image. At waypoint number “1” this is the best angle to fish the top as I am making my cast across the top and have a wide target area to cast to. At waypoint number “2” this is also a great angle to fish this top from in the way of coverage and the lest likely as to get hung-up in the top as you are bringing your lure through the top with the limbs. Waypoint number “3” would be the same s waypoint number “1” and the wind would determine if I wanted to fish this one instead of waypoint number “1”. The last one waypoint number “4” would be the worst one to fish as you would be pulling your lures through the limbs and the most likely to snag or hang-up your lures.

I hope you find this blog useful and the software and this tip will help you become a better fisherman and how to get the most out of your sonar units to catch fish. After all that is the reason, we spend the big bucks for these units.
