A fish finder is a device that sends out ultrasonic electrical waves at certain frequencies and when the waves bounce back to the unit it determines the depth of the water. When these waves hit something harder than water, ie a fish, the waves will return to the unit quicker than previously signalling something other than the bottom on the sonar.
Over and above, what kind of fish finder do I need?
To choose a fishfinder, consider the type of unit—whether it includes GPS and is part of a boatwide network, size of the fishfinder's footprint, resolution of the display, how much transmitting power you need, and what frequencies will work best in the inland, coastal or deep-water environment where you fish.
Just as much, what's better Garmin or Lowrance? The Garmin's side and bottom views are superior to the Lowrance. Much more detail seen, especially in shallow water where I mostly fish. Lowrance sonar is better than the Garmin's but I haven't had time to mess with any adjustments on the Garmin yet.
Hereof, do sharks show up on fish finders?
Not as good of a result. to allow them to swim & keep breathing. Sharks do not show up on a fish finder either, No you could have ten dozen Sharks under your boat and not one would show up. ... That is what show up and the depth finder, the bigger the swim bladder the larger the fish show up on your screen.
What is better side imaging or down imaging?
Down-imagingfish finders feature a transducer that directs sonar waves down beneath your boat, while side-imaging fish finders direct their beams to the sides of your boat. Both type is inherently better than the other, and both can help you find (and therefore catch) more fish.
