A depth finder device works using sonar that is designed to find fish. Newer versions of fishfinder devices generally include GPS navigation systems, but you can also purchase GPS devices separately. Many of these devices also include features that allow you to save your favorite fishing spots and find new potential fishing spots automatically.

A boat GPS can be purchased as part of a finder combo or separately. GPS devices not only provide co-ordinates and direction, but can navigate you to different locations. A number of these devices also include effective mapping functionality to enhance your fishing experience. Although you may only be aware of the Garmin fish finder or Lowrance depth finder devices, there are several others to consider. Learn about deeper fish finder options in the sections outlined below.

What is a boat GPS?

A boat GPS is a small, lightweight, handheld device that provides mapping functionality, simple navigation and GPS coordinates. In certain scenarios, such as if you ever became lost, or were caught in a storm, this device could become a lifesaver. In addition to included safety features, GPS devices commonly allow you to add locations, such as campsites, fishing docks and your favorite fishing spots. Utilizing such features, can help you to quickly move to saved areas, as well as discover new potential fishing spots. Boat GPS offer benefits such as:

  • Directions and GPS coordinates.
  • The ability to save checkpoints in and out of the water.
  • The ability to find new fishing spots automatically.
  • Additional features, such as alarm clocks, calendars, watches, tide information and ideal fishing days.

You may also want to consider a fish finder GPS combo device if you are considering the purchase of a GPS device, as combo devices include several additional features.

What is a fishfinder?

A fish finder is an invaluable tool to any avid fishermen. These lightweight, handheld devices use a type of sonar to measure depth and find fish using a type of sonar called a sounder. The use of a sounder allows the device to use sound pulses within the water, in order to paint a picture of objects and aquatic life of which the sound bounces off, such as a school of fish or heavy weed lines.

GPS depth finders primarily use sonar in a downward trajectory, while other devices scan up to 240 feet on each side. Some devices utilize a combination of both types of sonar technologies. The type of finder that may be best for you will likely depend on the type of saltwater fish you would like to catch. For example, if catching bottom feeders, you may find a device that utilizes sonar in a downward trajectory more useful.

Finding the Best Fish Finder GPS Combo

If you are interested in a fish finder or GPS combo device, it is important to review the common features that may be important to you, depending on the fish that you intend to catch, the time that you intend to fish and any personal preferences that you may have. This can help you to narrow down the features that you would like to have, which will assist you when comparing the prices of the best devices.

Display and Screen Sizes

Fishfinders come in a variety of sizes, but screen size is generally one of the most important features of these devices. The larger the screen and display, the more that you will generally be able to see on your radar. Additionally, brightness adjustment options and LCD displays can be key when utilizing the device, especially during early-morning or late-night fishing.

Glare Protection

If you are fishing on a particularly bright day, it can become difficult to see the display fishfinder screen without the proper glare protection on a device. While newer devices commonly feature glare-resistant screens, you can get by with an older device by purchasing special LCD films that cut out glare when applied. Some devices also allow you to adjust a screen’s brightness and contrast.

Note: Glare protection is especially important if you are seeking to purchase a kayak fish finder, since you will need to be able to see as efficiently as possible without any water coverage available to you.

Storage and Connection Options

If you have a boat GPS or finder combo, you will need to ensure that the device you purchase has adequate storage and connection capabilities. By doing so, you can ensure that you have more than enough storage to save all of your waypoints and check points, as well as any additional maps or updates that your GPS device may need. Alternatively, you can find a device that is capable of using an SD card, should you ultimately need more space.

Satellite Functionality

For a GPS to receive proper navigation, it must be supported by at least 12 satellites. While most GPS devices meet this minimum requirement, it is worth knowing that the more satellites a GPS is supported by, the more accurate your device will be.

Fish Finder Reviews and Suggestions

If interested in a fish finder GPS combo, it is worth taking a look at the devices that have garnished the most positive reviews from consumers, in order to narrow down your selection. Each device includes numerous features, and is available for a different price tag, so it is worth taking the time to review each one. Consider the:
