5.2 Bullet Transducer (Alternative/Optional)
While the HOOK2 12 typically comes with TripleShot, other models in the HOOK2 series may feature a Bullet transducer, which provides 2x wider sonar coverage for traditional CHIRP sonar. This option focuses on maximizing the area scanned directly beneath the boat.
6. Mapping & Navigation

6.2 GPS Plotter
The integrated GPS plotter provides basic navigation capabilities. You can:
- Add waypoints to mark important locations.
- Follow trails to retrace your path or navigate to previously visited areas.
