Hummingbird Fish Finder Tutorial

Fishfinder Components

Hummingbird fish finders are made up of three basic components: The fishfinder mounting bracket, the fishfinder display and the fishfinder transducer. Each unit comes with all you need to install and operate the fishfinder, unless otherwise specified. Options to transducers and mounting systems are available in the accessory sections of each of the fishfinder manufactures.

Fishfinder Transducers

Fishfinder transducers are the unit's "antenna". They convert the electric energy from the transmitter to high frequency sound. The sound wave from the transducer travels through the water and bounces back from any object in the water. When the returning echo strikes the transducer, it converts the sound back into electrical energy which is sent to the fishfinder's receiver.

Fishfinder transducers come in several forms including Portable Suction Cup Transducers so you can take the fishfinder from boat to boat or reposition it on the same boat; Shoot Through Hull for mounting in plastic and fiberglass hulls, (the signal shoots right through the hull); Through Hull fishfinder transducers which have to be mounted in a hole through the bottom of the hull; and Transom Mount Transducers which are standard issue with most fishfinders. Other variations include transducer floats for some of the radio frequency handheld units from Humminbird.

Water Temperature Sensor

Many fishfinders include a transducer which has a Temperature Sensor to tell you the surface water temperature. Other fishfinder transducers have a built-in Speed Sensor, or you can purchase a separate speed sensor if you need it. The GPS combination units will give you GPS speed but it will not be as accurate as the speeds sensors if you want to use it at trolling speeds.

Single and Dual Frequency Transducers

Another issue with transducers is the number of frequencies. Some Hummingbird fish finder transducers come with more than one frequency. Dual frequency transducers are for deeper water fishing. See the transducer information page for more information about how these frequencies effect a fishfinder's performance. As a rule of thumb, for shallow water fishing you want a Single Frequency Transducer, and for deeper water (great lakes or coastal ocean fishing), you want a Dual Frequency Transducer.

Fishfinders for Kayaks

Portable fishfinders work well for kayak installation. Because the shape is awkward for portable suction cup use, most people epoxy the transom mount transducer into the bottom of the kayak (assuming the kayak is plastic or fiberglass).

Single or Multiple Beam

Most fishfinders come with a single sonar beam, but some fishfinders come with a dual signal or multiple beams. These are useful for fishing in shallow water (such as for bass).

Side Imaging Sonar

Side imaging sonar shoots a sonar beam off to the side of the boat, which is great for shallow water fishing. However, it can be a little expensive for the weekend fisherman.

Fishfinder Mounting Brackets

Fishfinders usually come with a Transom Mount Bracket, but mounting bracket options including Gimbal Mounts, Flush Mounts(in dash), Swivel Mounts and some offer Quick Disconnect Mounts.

Fishfinder Displays

Fishfinder displays are the most expensive component of the fishfinder and there are two types, LCD (grayscale) and color. The LCD screens are less expensive but do not have as high of separation or contrast, especially in poor lighting or glare. If you have the budget, the color fishfinder displays are worth the money.

Fishfinder Transducer Extensions

Most fishfinders and transducers come with a twenty foot cable but you can purchase extensions for your transducers if your boat requires a longer cable. You can also get GPS receiver extensions for GPS systems or models with built in GPS capability, as well as additional cables for boats with multiple displays

Hummingbird Depth Finder Categories

Fishfinders come in three basic classes: Standard Fishfinders, with the options as outlined above; GPS Fishfinders which includes a built in GPS unit with either a built-in antenna or an external antenna; and Portable Fishfinders, which include a suction cup transducer and a portable carry case allowing the fishfinder to operate on batteries.

Standard Fishfinders

Standard fishfinders come with a fixed Transom Mount Transducer, cable, and everything you need to operate your fishfinder.

Portable Fishfinders

Portable fishfinders come in two types, packaged and component. If your needs include a second boat or a rental boat you can purchase a separate power pack and suction cup transducer to use the same display in two boats. This is very useful for use on vacation or for ice fishing. See accessories for the Hummingbird depth finder you purchase.

GPS Fishfinders

GPS Fishfinders are combination or combo units that have both a fishfinder sonar or depth finder as they are often called, and a Marine GPS Chartplotter or Trackplotter. On a Marine Chartplotter your position is superimposed over a moving map so that you can see your position at all times. A Marine GPS Fishfinder with a track plotter only shows your course. Both the Marine Chartplotter and the Marine Trackplotter will allow you to save your position (waypoint) for recall by name so you can get back to a particular position.
