  Do these work?

  I'm not talking about this brand, just in general.

  OK thanks.

  Not a fishing person but without knowing how these work, how would these contraptions pick up fish only amongst other debris in the water.

  Not doubting you but just curious.

  All fishfinders operate using Sonar. Developed during World War II, this technology uses sound waves to "view" underwater objects. A sound wave is produced by the fishfinder and sent through the water. At the source, the wave is narrow; however as it penetrates deeper, the sound wave spreads forming a cone, or what is commonly called a beam (think flashlight). When the sound wave encounters something within this beam, it bounces back to the fishfinder. By measuring the very small amount of time between when the sound wave was send out and when it bounces back your fishfinder calculates the distance and draws it on the screen.
  If the signal doesn't encounter anything along the way, it reaches the bottom. Soft bottoms like mud and weeds tend to absorb the signal. Hard bottoms such as rock reflect a stronger signal back. These subtle differences in sonar reflections appear on the display screen. That's how a fishfinder "reads" the bottom and everything in between.

    I think a common misconception with these things is that they will locate the good fishing hotspots. Pretty much all they do is allow you to verify if there are fish under the boat, you still need to find the great spots (and catch the fish!). But once you find a good spot you can also bang it in the GPS for next time.

  It is 2nd Gen but the new 3rd gen have only just been released so for the price I would go for it if you can afford it.
