ELING 3 3/8″ GPS Speedometer 35 MPH
The ELING 3 3/8″ GPS Speedometer provides a compact option for jet skis and small vessels. It supports a speed readout up to 35 MPH (55 KM/H) and includes options for odometer and TRIP/COG readings. Installation notes recommend cutting an 85mm hole with a 70mm behind-panel clearance and securing the GPS antenna outside or behind a windscreen to ensure a clear sky view for satellite reception. The unit is designed for 12V or 24V systems, aligning with common jet ski electrical configurations. It can display Current Speed and an ODO that cannot be reset, making it suitable for basic navigation and performance tracking.
Key features include: sturdy panel mounting, a reliable antenna connection, and a simple interface for speed measurement. If you need a different color faceplate, additional ASINs are available from ELING. While suitable for many watercraft, users should verify panel depth and mounting clearance on their specific jet ski model.
ELING 85mm Waterproof GPS Speedometer 0-60 MPH
This 85mm size speedometer offers a broader display for easy reading in bright sun or spray. It’s rated for 12V and 24V operation and offers red and yellow backlights for greater visibility in various lighting conditions. The product notes emphasize securing the GPS antenna in a location with a clear view of the sky, typically outdoors or near the windscreen. The gauge provides a straightforward speed readout and is designed to remain accurate with quick satellite lock times after initial setup. For boat and jet ski enthusiasts needing a larger display, this model is a strong candidate.
ELING 52mm Waterproof Digital GPS Speedometer
The compact 52mm digital GPS speedometer suits riders who want a minimal gauge footprint on dashboards with limited space. It includes a robust set of wiring indicators (green/white external button, green, yellow, white, purple, blue, red, brown, orange wires) to support various vehicle functions beyond simple speed tracking, such as fuel level, high beam, turn signals, and oil pressure. The unit requires a GPS antenna installation for sky visibility and emphasizes not cutting the antenna cable. This model is ideal for smaller watercraft or those seeking a discreet, multi-utility display on a dashboard with tight space.
ELING 3-3/8″ GPS Speedometer Odometer 0-80MPH
This model expands the speed range to 0-80 MPH (0-120 KM/H) and includes an odometer. It supports a panel cut of 85mm with a recommended 70mm behind-panel clearance and requires secure antenna mounting for reliable satellite reception. The unit’s backlight options include multiple color choices to improve readability in various environments. It is designed for 12V/24V systems and integrates a simple interface that shows Current Speed, and a selectable TRIP/COG or ODO. If you need multiple color options, ELING provides additional faceplate ASINs for customization.
ELING 85mm GPS Speedometer 0-80 MPH with Backlight
This 85mm gauge offers 0-80 MPH speed range with red and yellow backlights, designed for jet ski, sailboat, and small boat applications. It requires a 12/24V power supply and uses a GPS antenna with a clear view of the sky for reliable satellite reception. The installation notes stress the importance of sealing around the gauge with appropriate hardware to protect against water intrusion. This model is well-suited for riders who want a bold display that remains legible in bright daylight and rough water conditions.
Buying Guide: Key Purchase Considerations
When evaluating the best GPS gauges for jet skis and watercraft, consider the following factors:
- Display readability: Backlit displays (red, yellow, white, etc.) improve legibility in bright sun and spray. Larger gauges are easier to read from a distance, while smaller gauges conserve panel space.
- Panel cutout and installation depth: Ensure the gauge size (usually 52mm or 85mm) fits your dash and that behind-panel clearance is adequate for wiring and mounting hardware.
- Power compatibility: Most jet skis use 12V or 24V systems. Confirm your craft’s voltage to avoid overloading or incorrect operation.
- Antenna placement: A clear sky view is essential for fast satellite lock. Outdoor mounting or placement behind a windscreen is commonly recommended.
- Functionality: Some models emphasize odometer, trip, or course (COG) data, while others prioritize straightforward speed readouts. Decide which metrics matter most for your usage (racing, training, or casual riding).
- Durability and weather resistance: Waterproofing, vibration tolerance, and robust casing protect against salt spray and rough water conditions.
- Compatibility and accessories: Check if faceplate color options or alternative ASINs are available to customize appearance or match existing dashboards.
- Warranty and support: A reliable warranty and responsive support can help with long-term reliability and parts availability.
In selecting a GPS speedometer, weigh how you plan to use it on your jet ski or watercraft, the space available on your dash, and how quickly you need to lock onto satellites. The ELING models featured here cover a spectrum from compact 52mm gauges to larger 85mm displays, with various backlight options and features. The STOPBYUS cover adds a practical, protective accessory for those who transport or store their watercraft frequently.
