The Striker 4 is easy to use and shows clear fish patterns. I can mark spots and return to them easily. The GPS is accurate and the sonar history rewind helps me review past catches. Great for both beginners and experienced anglers.

I’ve used it on several fishing trips and it consistently finds fish. The color screen is bright and the CHIRP sonar gives better detail than older models. The only thing I’d improve is the transducer compatibility, but it’s still very reliable.

The smooth scaling feature makes depth changes seamless. I can switch between scales without losing image continuity. Marking hot spots and sharing routes with friends has made fishing more efficient.

It’s a solid fish finder with good sensitivity. The built-in GPS works well for navigation. I haven’t used the GT8 or GT15 yet, but the current transducer performs well in most conditions.
