Measuring Your Musky We all spend a lot of time and money trying to catch Muskies. So, it is only common sense that we spend a little money to make sure that we have an accurate measurement. Four years, we struggled with all kinds of measuring devices attempting to get a good measurement of the muskies that we catch. These are all very accurate measuring devices if you are measuring wood, glass or some other fixed material. Unfortunately, they are not that effective when you are on choppy water and trying to measure a fish covered in Muskie slime at the same time you are trying to deploy any of the measuring devices shown above.
