Fish finders detect the presence of fish primarily by detecting the air in their swim bladders. The air conserved in the swim bladder changes the sound path and reflects energy back. The fish finder detects this reflected energy and converts it into fish images on the screen.
How deep can fish finders work?
For every 100 watts of power at 200 kHz, your fish finder will show depth reading of up to 100 feet.
What technology do fish finders use?
A fish finder works thanks to sonar technology. Sonar stands for SOund NAvigation Ranging. It sends sound waves into the water in the form of pulses or pings. When the sound waves hit something, the sound is reflected back.
Do fish finders work when not moving?
2D, Down Imaging, and Side Imaging are designed to work from a moving boat, they’re not made to work sitting still (or barely moving). It’s possible to adjust the fish finder speed and settings to have a general idea of what’s below the boat but you’re not going to get detailed images.

How long will a 12V battery run a fish finder?
A typical fish finder battery may be 12V 10Ah. This means that the battery has 12 volts. You can expect it to last for about 10 hours at that voltage.
At what speed will a fish finder work?
Fish finders with transducers that are installed properly can mark the bottom at relatively high speeds — up to 40 mph in some cases, though the slower the boat speed, the better the on-screen images.
Why is my fish finder not showing fish?
Transducer Orientation – improper orientation of the transducer can cause the depth sounder to not ‘see’ fish. For a unit to be able to show fish, it must have a transducer that is facing straight downward. Most transducers must also be oriented in a particular direction with respect to boat movement.
Is it a good idea to run fish finders on separate batteries?
When connecting your fish finder to power, it is important to use separate batteries for the engine generator and the fish finder if possible. The reason for this is that there can be a lot of engine noise interfering with the signal to the fish finder.
Can you hook fish finder straight to battery?
Wire the fish finder direct to the battery (either the cranking battery or an auxiliary battery). Don’t take shortcuts and run the fish finder power wire into a block or switch panel. Wire your fish finder the right way and extend the Humminbird power wire directly to the battery using the correct type and gauge wire.
How long will a fish finder last?
Make sure to upgrade your fish finder on a regular basis. Once your finder is about four years old you should seriously start thinking about replacing it. If it is over six years old then it is likely overdue.
Is it worth having a fish finder?
Fish finders are well worth the cost if you plan to use them. They might seem like an expensive investment upfront but they can make the overall fishing experience a lot more fun in the long run. Simply put, they are an additional electronic tool for your boat or kayak that helps you to catch more fish.
What is the difference between a fish finder and sonar?
The difference between a fish finder and a Sonar
While Fish Finders can detect echoes under the ship, Sonars can detect schools of fish all around the ship, making it one of the most efficient way to search for fish.
What is the difference between a depth finder and a fish finder?
A depth finder can only provide information about water depth. While a fish finder will provide data on fish, structure, things in the water, depth, and much more.

Are fish finders useful in shallow water?
You’ll be happy to learn that both side imaging and down imaging work remarkably well in shallow water. Side imaging is often best – depending on how shallow or murky the water is, bottom structure might be easy enough for you to register without your fish finder.
