What is Teachin Fishin?

Lance Valentine


If you’re an angler fishing has a special place in your life. Maybe it’s memories of fishing with family or friends, going to beautiful places, spending time on the water to clear your head or the simple joy of catching a fish. No matter what fishing means to you, there are 2 things that most anglers can agree on.

  • 1. Catching fish is fun
  • 2. Catching MORE fish is MORE fun

That is what our goal is at Teachin Fishin; helping anglers catch MORE fish, MORE often to get MORE enjoyment from their limited fishing time by providing fishing education and information that has been tested and proven over the years. Whether you are a new angler or a seasoned veteran, Teachin Fishin has information you can use right now to become a better angler. Our fishing education information is available in both written and video format and is available in quick snippets under a minute or in detailed courses that last several hours-all designed to be easy to understand and apply on the water.

January: Everything Sonar

We all believe “you can’t catch fish where there are none”, and most of our members have at lease a basic understanding of how sonar works. This month Captain Lance digs a little deeper past basic interpretation as he explains the little things that can make a big difference when using your sonar unit.


One of the most common questions I get asked by the fishing public is “Why can’t I see more on my sonar?”. A simple answer isn’t available, but after a few questions of my own, a solution can usually be found. Below are some of the most common mistakes sonar users make and how to fix them. Be sure to perform the following steps in the order listed to set your unit properly.

Today's fishing electronics are amazing pieces of equipment. With the ability to mark fish at 70 mph, look down and sideways for fish and use GP:S navigation to get us to our fishing spots, these units are changing the way we fish. One of the most often asked questions we get about electronics pertains to transducer mounting. If transducers are mounted properly, your sonar unit has the capability to produce high-quality 2D sonar readings at speeds up to 70 mph and StructureScan readings into the 30 mph range!

Over the past few seasons DownScan and SideScan sonar imaging have changed the way most anglers search for, and locate fish especially in heavy cover, close to bait or close to the bottom. Due to the higher frequencies used, DownScan sonar will provide a more detailed, almost 3D image of what is below the boat.

In the 2 decades I have been teaching sonar use and interpretation, the misunderstanding of fish "arches" is still the biggest issue most sonar users have, and it is probably the biggest reason that most anglers do not trust or fully understand what they are seeing on their screens. We've all seen the beautiful ads-a sonar screen full of fish arches. Although you may often see perfect, full arches on your sonar, don't despair if you can't. The geometry of making a fish arch is simple, but must be completely satisfied before a fish arch will appear on your display.
