Buying Guide
- Power and voltage compatibility: Most options operate on 12/24V. Verify your boat’s electrical system to avoid installation issues.
- Display readability: TFT and backlit displays excel in bright sun and low-light conditions. Consider color options for easier nighttime use.
- Size and fit: 85mm gauges fit standard 3 3/8″ panels; 52mm gauges use tighter panels. Check panel depth to ensure proper clearance behind the dash.
- GPS antenna placement: A clear view of the sky improves satellite lock time. Place antenna outdoors or near a windscreen with minimal obstruction.
- Units and features: Choose mph, km/h, or knots. Some models include a course readout or odometer, others emphasize speed only. Your choice should align with preferred data outputs.
- Durability: IP67 waterproof and anti-fog glass protect against splashes and spray common on ski boats and jet skis.
- Wiring and installation: Ensure you have a secure mounting method (M4 nuts and brackets are common). Do not cut GPS cables and follow manufacturer cutout guidelines.
