Main Features

  • HD color display

  • Senses fish up to 328 feet down below
  • Long transducer cable
  • Runs on 4 AA batteries
  • Easy-to-see display format
  • Five sensitivity settings

With the simple LCD screen this device is equipped with, anglers can see data displayed in green with gray in the background. It has an anti-UV coating which allows for the device to last longer in the sunny summers. Additionally, this portable fish finder uses simple graphics for displaying data and shows information like the depth of water and the size of any sonar hits. While the screen is simple-looking, it does show important information with an easy-to-see format.

Moreover, this portable fish finder works at depths of 3 feet down to 328 feet. While that is just the depth of the sonar, the connecting cable on the other hand is 25 feet long which means anglers can get reading from as deep as 25 feet away from the current position. One drawback claimed by anglers is that the device is not waterproof. This restricts them to an extent and requires for them to be cautious not to submerge the device in the water. However, the transducer and the sonar sensor are both waterproof.

Another feature that makes this device the best portable fish finder is its sensitivity settings which allow anglers to adjust the sensitivity according to their preference. There are five different sensitivity settings as per which you can save the device’s battery life or display a full range of data for several minutes. One setting can work as a battery-saving mode where the screen stays off. The other setting of backlight mode can help anglers see things clearly on the screen at night.

Since ice water is just above 32 degrees, anglers are good to go for ice fishing. Using this, they can detect fish underneath the ice before they drill a hole and clear a patch of ice by removing any snow. All that needs to be done is to place the sensor on top of the ice pointing downward so it picks up movement. The other option is to drill through the ice and let the transducer down into the water.

Pros

  • 25-foot transducer cable
  • Option to mount it to the boat or hang around your neck

Anglers get the benefit of planning their fishing trip in advance and heading to fish-loaded spots on lakes by saving a series of waypoints. This is especially useful as Garmin saves the points in an alphabetical listing and allows viewing options to see real-time locations. An added bonus with this feature is that anglers can electronically share these waypoints with other Garmin users.

The built-in flasher is another amazing feature that can prove to be of great help. Instead of using a separate flashlight for vertical fishing presentations, Garmin Striker 5DV users can switch to the sensitive flasher display options. In this display, anglers can get information regarding the bottom type, depth, vegetations, as well as depth of individual fish that are near their boats. Some professional anglers like to monitor their lure or bait as it moves through the water column to note the reaction of fish that they have marked.

While other portable fish finders focus on providing anglers with the basic required features, Striker 5DV is a device that stands out. This is mainly owed to its versatility and how it is designed to be suitable for both saltwater and freshwater fishing. The displayed readings are accurate to 2,300 feet in freshwater.

Along with that, this portable fish finder comes with a portable carrying case which allows for anglers to transport their device anywhere conveniently.
