Not this model. The listing is for the STRIKER Cast Without GPS (010-02246-00). The Striker 4 has a built-in GPS receiver and stores 5,000 waypoints.

Which reads deeper water?

Garmin rates the Striker 4's 200 W RMS dual-beam sonar for deeper water than the castable unit, which is built for shallower shore, dock and ice fishing. The Striker 4 also lets you switch frequencies for deep structure.

Is the Striker Cast worth $17.99 more than the Striker 4?

Only if you fish from shore or ice and cannot mount a unit. It hit $129.74 on October 28, 2026, so watch for it to drop back near the Striker 4's $132.00.

Which lasts longer on a trip?

The Striker Cast runs 10+ hours per charge on its internal battery. The Striker 4 draws from your boat battery, so runtime depends on your supply, not a fixed figure.
