Types of Fish Finders

A fish finder works by sending sonar waves underwater that bounce off objects in the water. These waves identify fish and other structures, and the best models can even detect their size. They also can help you locate ideal fishing spots by reading the changes in elevation beneath the water. There are several types of fish finders, each with its own pros and cons. used fish finders

Most fish finders come with only one transducer, but some anglers will want to use two transducers. Having two transducers on your boat can give you different options and can help you find fish faster. However, it’s not recommended for smaller boats. When using two transducers simultaneously, make sure they operate at different frequencies.

The transducer is a vital component of any fish finder. It determines the quality of the image, and a poor-performing transducer will not offer accurate data. A high-quality transducer will send sonar waves into the water, providing a clear image of what’s beneath your boat.

The Humminbird MEGA series uses a 1200 KHz frequency for crystal-clear imaging. The HELIX MEGA DI G3N model adds to the MEGA line of fish finders. Garmin has also added megahertz capabilities to some of their ECHOMAP, Ultra, and GPSMAP units. However, to get the 1.2 MHz SideVu frequency, you must have a transducer with the GT56UHD-TM format. The same goes for the DownVu frequency.

While there are some differences between fish finders, the HDS Live is the most impressive one on the market. Its ultra-clear screen has a large viewing angle and a super-clean resolution. It also comes with a solar-powered backlight. The HDS Live split screen feature has six views on one screen, making it ideal for navigating the water.

A fish finder with integrated sonar may be able to share data between units when the two are on the same boat. However, it will lose functionality when the transducer is stowed. Therefore, you will need a second transducer on the transom or the bottom of the hull. Some people even purchase two fish finders and use a splitter cable to connect the devices.

Different models use different frequencies to pinpoint the position of fish. In some cases, CHIRP technology is used to detect fish, and it has traditionally been reserved for saltwater fishing boats. However, fish finder manufacturers are finding ways to process CHIRP signals in shallower water. Lowrance has a great primer video on this new technology, which can be used on a variety of fishing boats.

A fish finder can come with different types of transducers, each with different mounts. The transom mount is the easiest to install and requires little effort, while through-hull mounts require a deeper hole in the boat. Transom mounts can be used on most boats, while thru-hull mounts are ideal for boats with fiberglass hulls.
