The 6 Best Portable Fish Finders To Help You Find Fish Anywhere

The Garmin Striker Cast castable sonar is about as portable as you can get these days. Just pair the castable device with your smartphone and you’re able to hunt for fish just about anywhere. The Striker app turns your cell phone into a mobile fish-finding device that you can use from the shore, a dock or any boat. The sonar streams wirelessly for at least 200 feet in both saltwater and freshwater, and the device sets itself apart from other similar devices with an easy-to-read 2D sonar mode, or a more traditional ice fishing flasher mode. It also lets you adjust the gain and range to dial in the settings. And with the map history Garmin offers, you can download a variety of contoured maps to help navigate uncharted waters. 

Pros:

• Cost effective
• Compact and portable for travel
• Maps courtesy of Garmin

Cons:

• Requires a cast
