Key features and what they mean for you
This gauge drives its needle with a moving-magnet mechanism, delivering a smooth, tactile indication that remains steady even on choppy days. Its stepping motor supports a full gauge range with improved precision and lower power draw, contributing to longer life and less battery strain during long trips.

- Ultra-wide operating voltage: long-term 9–32V, with brief tolerance up to 36V for surge protection.
Electrical flexibility and compatibility
Designed to be compatible with multiple fuel level sensors that share a common signal, the gauge accommodates several signal ranges to fit different tank configurations. This makes installation easier and reduces the need for additional adapters.

- All-weather, fully waterproof construction protects the electronics and display from moisture and splashes.
