How far does a fish finder go?

If you want to fish in a deep water lake or saltwater, you should get a fish finder with as much power as you can afford. Important note: For every 100 watts of power at 50 kHz, your fish finder will show depth readings of up to 400 feet.

Do fish finders show depth?

Fish finders are ideal tools for reading depth, seeing the bottom contour and finding underwater features. Sometimes this information will be more valuable to you than actually marking fish.

How shallow Will a fish finder work?

Some auto depth finders default to a minimum number of feet – something like 30 feet. If you're fishing in a water column that's much shallower than what your Auto settings detects, you can manually adjust the bottom of the water column up.

What is the difference between a depth finder and a fish finder?

This is more commonly utilized for shallow water depth detection, when a graphic display is not required. A "fish finder" uses the same or similar transducer and actually gives a graphic, video image of the water and bottom under the boat, as well as several seconds or minutes history.

Can fish hear fish finders?

Can fish detect fish finders is a hot discussion. However, in reality, it's nearly impossible for fish to detect fish finders. Such devices don't produce enough noise or waves to make them detectable. Neither is the frequency the transducer transmits audible enough to scare or notify fish of danger.

Can you use 2 fish finders at the same time?

Any time you run two units with the same frequency there is a risk of interference. However, with the modern noise rejection systems built into today's fish finders, in most conditions when there is a unit on the front and back of the boat with the same frequencies, they will not interfere with each other.

What is best frequency for shallow water?

As a rule of thumb, use frequencies below 140 kHz when fishing very deep water (over 1500 feet). Between 600 and 1500 feet, frequencies between 100 kHz and 160 kHz tend to work well. For anything 600 feet or shallower, you should use higher frequencies – over 160 kHz.

How shallow will side imaging work?

Will Side Imaging work well in shallow water? Yes. In as little as two feet of water the Side Imaging units will show great detail of objects 50-75 feet away from the boat.

What do rocks look like on a fish finder?

Rocks show up as hard bottom with bumps. The bump size depends on the size of the rocks. I use the side scan to find boulders off to the side, regular sonar (2D) and DownScan to find rocks and determine their size. The DownScan shows big rocks as spikes.

Do you need a depth finder?

Fish finders are not needed in order to locate and catch fish but they do provide highly valuable information like water temperature, water depth, bottom topography, the presence of fish, baitfish, as well as structure such as weeds, rocks, laydowns, and shelves.

Do depth finders work at speed?

Just about all of the brands will work at high speeds if you mount the transducer just right, and just about all of them will fail if they're not just right.

Can you run two fish finders off one transducer?

While it is not recommended that more than one transducer be run simultaneously, there can be multiple transducers installed on a boat. If two transducers are transmitting at or close to the same frequency and the signals cross, interference may appear on the display of your Garmin Marine Chartplotter.

What is a disadvantage to the side scan sonar?

- Small objects (dm range) can be detected. Disadvantages: - No penetration below the seabed. - No precise geo-referencing. - Not suited for detection of most Stone Age sites.

Which is better down imaging or side imaging?

Side imaging is going to be more useful in shallower water or when you are scanning for shallow diving fish, whereas down imaging sonar is going to serve the deeper fisherman who are fishing vertically better.

Is it OK to turn on 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.

Is CHIRP better than sonar?

CHIRP fishfinders transmit a longer pulse than traditional sonar, putting more energy into the water column, with a true broadband frequency range of up to 117kHz. Instead of pinging a single frequency like traditional 2D sonar, CHIRPing devices transmit a sweeping range of frequencies.

How long does a transducer last?

The more you use it the smaller(weaker) it gets. I usually replace mine every 5-6 years and have noticed improvement each time. Of course this improvement could just be due to newer technology.

How close can transducers be mounted?

Make sure there is nothing in front, behind, or to the side of the transducer that is closer than 12". Do not mount the transducer where it could be damaged from trailering, launching, or storage.
