We made it to part 3 of understanding fish finders and sonar. In this article, we will uncover more advantages to using fishing finders (sonar) and help you catch more fish!
Believe it or not, a very simple but important function of the fish finder (sonar) is just to let you know how deep you are fishing. If the fish are holding in 20 feet of water, and you are in 40 feet of water, you will certainly have a nice day on the water, but you won’t catch any fish.
Without a fish finder, it is very difficult to constantly know how deep you are fishing. Of course there are manual ways to try and figure out water depth, but using a fish finder is quick, easy and extremely accurate.
Another very important thing a fish finder (sonar) can tell you is when there is a change in the bottom composition. For example, if you have a sand bottom and then it suddenly changes to a rock bottom – this “transition” area is a natural game fish magnet and both salt water and fresh water game fish will relate to this change in the bottom.
Usually, a soft bottom (sand or mud) will be shown as a thick grey line on the bottom of your fish finder (sonar) and a hard bottom (rock) will show as a thin grey line on the bottom of your fish finder (sonar). Look for those transitions because if you find them, they are like gold! Mark your GPS!
Using your fish finder (sonar) to find bait fish is yet another way to put you on to more fish. Bait fish will not show up as “arches” but rather they will be very small lines, almost like debris. Usually, there will be large schools which show up as thick “debris” on your graph. This signifies that there are big schools of bait fish and where there are bait fish, the game fish are usually right there following them.
In fact, if you happen to see “balls” of debris, this would be bait fish that have swarmed together in a ball because usually, that indicates something is chasing them and they move into this “ball” formation as a safety defense.
Bottom line is, when you mark bait fish, get you lures down there as you are certain to get into some aggressive game fish!
If you have a boat, be sure to install a fish finder (sonar), keep in mind some of the tips from this 3 part series, and you will increase your chances of catching more salt water or fresh water game fish!
Until next time, good luck and good fishing,
