ELING 85mm Waterproof GPS Speedometer Kit
This 85mm gauge is designed for 12/24V systems with a clear 85mm hole installation option. It includes red and yellow backlight variants for visibility in bright or low-light conditions. The GPS antenna should be secured outdoors or behind the front windscreen to maintain an unobstructed sky view for satellite reception. The unit emphasizes a straightforward installation process and reliable digital speed readouts.
Best for: Boat owners who want a bright, robust 85mm gauge that is easy to mount and read at a glance. Particularly suitable for 12/24V marine systems and those who value bright backlighting for day and night use.
Caution: Ensure clearance behind the dash is at least 55mm to accommodate the gauge depth. Do not cut the antenna cable and connect it to the back socket for proper operation.
ELING 85mm Waterproof 80 MPH GPS Speedometer
This model offers a faster GPS lock with an 85mm housing and an emphasis on course readouts rather than odometer data. It uses 12/24V power and requires a flat mounting area. Guidance notes include secure fastening of the GPS antenna in a clear-sky position. If the signal is momentarily missing, a reconnection of wires and a restart may restore data quickly.
Best for: Operators who need quick initial signal acquisition and a course-oriented display for marine or jet ski use. It can be a strong pick where fast lock times matter more than extensive data logging.
Caution: The recommended mounting depth behind the panel may be up to 70mm; ensure the chosen dash area can accommodate the depth and bracket assembly.
MAIMEIMI GPS Speedometer 85mm (White TFT)
This 85mm gauge features a TFT display and a broad voltage range (9-33V), with IP67 protection and anti-fog viewing. The unit supports multiple speed units (km/h, mph, knots) and is designed for boat, marine, or vehicle use. Installation involves cutting a panel hole and securing the gauge with M4 nuts and brackets. It aims to provide clear, legible data in adverse weather or spray conditions.
Best for: Boaters needing a versatile display that handles several units and offers a crisp TFT readout. Ideal for mixed-use vessels and those who prefer a white face with strong backlighting for daytime visibility.
Caution: While the unit speeds are flexible, ensure you follow the depth clearance guidelines to avoid contact with other dash components.
ARTILAURA GPS Speedometer 85mm (White)
With 7 color backlight options, this 85mm GPS speedometer emphasizes customizable illumination and stainless steel bezel aesthetics. It supports up to 0-80 MPH and is IP67 waterproof. The unit relies on satellite data, reducing the need for external speed sensors. It is designed for boats, cars, motorcycles, and trucks, offering straightforward unit switching and robust weather sealing.
Best for: Boaters who want a visually striking gauge that can switch backlight colors to suit cabin lighting or personal preference. Suitable for vessels where a stainless aesthetic complements the dashboard.
Caution: Some users may prefer a more traditional color scheme; ensure the color setting aligns with existing cockpit illumination for readability at sea.
KUS Waterproof 85mm Digital GPS Speedometer
This unit emphasizes broad unit compatibility with 0-999 knots, km/h, or mph readings and a 12/24V supply. Installation uses the standard 85mm diameter and a depth requirement compatible with many dash panels. It is designed for multiple watercraft types including sailboats and jet skis, making it a flexible choice for mixed fleets.
Best for: Users who need wide speed-unit options and a robust, rounded 85mm gauge that fits common panel cuts. Good for users who track multiple units depending on weather or voyage type.
Caution: Knots mode is included but verify your preferred unit is easily selectable in the cockpit without adding complexity during operations.
Buying Guide
What to consider when selecting a ski boat GPS speedometer:
- Power and voltage: Most units run on 12/24V. Confirm compatibility with your boat’s electrical system.
- Mounting depth: Check the recommended panel cut and back clearance to ensure a snug, secure fit without interfering with gauges behind the dash.
- Display readability: TFT or LED backlight helps with visibility in glare or low-light conditions. Consider backlight color that matches your cockpit aesthetics.
- Units and data: Decide which units you prefer (mph, km/h, knots) and whether odometer data is needed or if course data suffices.
- GPS antenna placement: A clear sky view improves lock times and accuracy. Outdoor mounting or front windscreen mounting is common.
- Water resistance: IP67 is common; ensure the gauge and connections are sealed against spray, rain, and humidity.
- Speed range: Models vary up to 80 mph or 999 knots. Choose a range suitable for your boat type and typical speeds.
- Maintenance and wiring: Avoid cutting cables and ensure clean, secure connections to prevent signal loss or corrosion.
