Right away, I leaned how much I have come to depend on sonar when fishing. Even though I was using the Harris on a lake I have fished most of my life – much of in my youth without the aid of fish- and bottom-finding sonar – I felt blind without a fish-finder to reference. I found myself using other methods for determining water depth and possible fish locations, including topographic maps, studying shoreline features and even using my rod tip or anchor to physically test the depth of the water under the boat. It was a real learning experience and an exercise I recommend to any angler. You never know when, like me, you may be “forced” to fish without the aid of electronics.
