Basics Of Fish Finders

Fish finders could be the missing element that helps you to catch more fish. Here is some basic information on how to use  fish finders.

Fish finders can be either permanently mounted to a boat or can be portable units. If the permanent unit is used, it can be mounted professionally or by someone who is handy and can follow instructions. Portable fish finders can be used on a boat or through the ice. These units come in different models and styles and use different size batteries.

Fish finders work by sending an electrical signal to the transducer. This signal is generated by an amplifier. The energized crystal then reverberates at a particular frequency. This converts the electrical signal into mechanical acoustic, or sound energy. This acoustic energy causes the water molecules that the sound is traveling through to oscillate. The sound pulses in a defined beam. These beams are in a wave pattern instead of a straight line. The acoustic pulse travels through fresh water at approximately 4920 feet per second and 4800 feet per second in saltwater.

When the beam strikes an object, such as a the sea bottom, a fish or other structure, this causes some of the energy to be reflected back to the transducer. This information is collected by the transducer and sent back to the unit where it is processed into displayable data. The time difference between transmission and reception is calculated and given a range of depth. This is displayed as a number or an image on the screen.

Fish Finders Will Help You Spot Bottom Differences

Soft bottoms and hard bottoms reflect different strengths of signal. Mud and weeds on a soft bottom will absorb more of the signal. A hard bottom will reflect back a stronger signal. The display screen will show these subtle differences. This is how fish finders “read” the bottom and hopefully, show fish in between.
