Let’s see the features provided in the model and how you can use them.

  1.  It is actually the SONAR technology that allows the fish finder to look for fishes. SONAR technology works in the following way. It sends out the waves which when strikes with some obstacle reflect back. Softer object absorbs the waves while harder objects reflect them back. This system works better in the areas with less muddy or fewer weeds grown areas. To resolve this issue, some models of fish finder send multiple sound waves. The term cone angles or the core beams may sound familiar in context to the fish finder. This measurement of the beam is in degrees. The higher number of degrees represent the broader beam. A 12-degree cone is much smaller than the broad 32-degree cone. It is measured by -10db.
  2. Sensors which send out the sonars are portable transducers. The sensors are placed in water in these kinds of fish finders.
  3. Hard-wired and boat connected sensors, which are bigger than the portable sensors that are placed in the water are called transducers. This device sends out the sonars.
  4. There are two types of display screens, Grey screened and high definition color models. The sharper image is produced with higher contrasts.
  5. Maps and chart-plotting help you in finding your way.
  6. There are some brands (Garmin etc) which have trademarked technology or some features that are of that particular brand. Other brands may also contain that technology or feature but with the variation or different quality. Again it comes to what you are looking for in the product. Search for the brand that has a trademark in your requirement, let it be high contrast display screen and buy that product. But make sure that product is the best in that feature.
