Choosing the right fishfinder transducer is a task that requires some basic knowledge on the technique of a transducer, the model of fish-finder and some basic experience. A transducer can be attached to a boat in many ways. There are basically two types of finders: fixed mount and portable..
A transducer helps in converting electronic pulses that are emitted by the fish-finder to sound waves that travel down through water. When these waves hit the terrain or a fish, the echo that is returned is picked by the transducer that converts it into electronic pulses. The fish finder converts these pulses into a picture. When the pulse has a higher frequency, the resolution of the image is also better.
One important point to note is that all fish finders are designed to work only with a specific or a couple of frequencies. When you intend to buy a transducer, you need to ensure that the model works with the frequency of the transducer. This rule applies to both kinds of fish finders.
Obviously, the color fish finder is much easier to read. When you look at the screen of the fish finder, it will show 3 colors red, yellow and blue. The blue is the easy one; it is showing the water under the boat. The red on the screen shows the top of the water and anything dense underneath the boat. If you see arches under the red balls it means the fish are pushing the bait towards the water surface.
It uses a highly sensitive digital filtering process that enables the user to troll faster and see the fish that are under and around the boat. Also, in shallow water it cuts through the clutter and makes it easier to see the fish at that shallow water depth. This is the usual depth that the average angler fishes.
It doesn't show the density of what is underneath the boat, the monochrome fish finder just shows the bait balls and the arches. It only shows them in black, which makes it harder to differentiate between the bottom and what is actually fish. Also, the monochrome fishfinder choices usually come in smaller size screens than that of the color fish finder models.
