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.
Do fish finders scare fish away?
Noisy motors aside, fish finders scare fish away, at least those that are loud enough to create vibrations underwater. You may actually want to avoid using a fish finder, which is a device that sends sound waves through the water to identify fish, to increase your chances of scoring a bite.
Does a fish finder show fish?
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. This video image will show any objects detected by the transducer. This would include the bottom as well as fish, wrecks, etc.
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.

What do fish look like on a fish finder?
On most 2D fish finders, fish show up as arches with the middle of the fish pointing upwards on the screen. This is because the fish are in motion, moving through the sonar cone, casting back a slightly different signal based on where the sonar cone has hit them.
Where should I place my fish finder?
The best position for these types of transducers should be as close as the centerline of the boat as possible. Keep all other protrusions at least 12 inches away from the transducer. Protrusions such as rivet lines or strakes can lower the quality of your results when you finally have the fish finder set up.
Why does my fish finder not work at speed?
Seeing poor performance at speed usually indicates that the transducer needs to be mounted lower so that face of the transducer is in contact with the water at speed. To make this adjustment, loosen the mounting screws, and slide the transducer 1/2″ lower and re-test. New holes may need to be drilled.
