How does sonar fish finder work?
A sonar device sends pulses of sound waves down through the water. When these pulses hit objects like fish, vegetation or the bottom, they are reflected back to the surface. The sonar device measures how long it takes for the sound wave to travel down, hit an object and then bounce back up.
How does a fishing transducer work?
The transducer is the piece that does all the work. The transducer sends sonar waves (sound waves) down into the water.They send a flash sonar pulse down to the bottom of the waters and bounce back when they hit an object. The use the time it took for the signal to come back to determine depth and object intensity.
Can you turn on a fish finder out of water?
It is not recommended to run a FishFinder and transducer on a boat that is not in the water as you will not get any readings from the transducer.Without the water, the transducer could burn out and have issues if left running for an extended period of time out of the water.
Do fish finders actually show fish?

What angle should my transducer be at?
The transducer should be mounted nose-up about three degrees in relation to the plane of the hull bottom. Sometimes a transducer mounted parallel with the hull bottom also works fine, but even the slightest nose-down angle can cause turbulence or cavitation that kills performance.
How far should a transducer be in the water?
You should place the bottom face of your transducer about flush or slightly below flush of the hull. No more than 1/2.
What do the colors mean on a fish finder?

With Day Mode display, the intensity of the sonar return from a hard bottom will be shown in orange and a soft bottom will be purple. Day mode colors range from purple (softest) to red to orange to yellow (hardest).
What does chirp do on a fish finder?
By covering a wide range of frequencies, CHIRP produces more accurate, more detailed returns of fish, structure and the bottom. CHIRP stands for Compressed High Intensity Radar Pulse. That’s a fancy way of saying it can show you fish that other forms of 2D sonar can’t.
