ELING 85mm GPS Speedometer 0-60 MPH Kit
The ELING 85mm GPS Speedometer 0-60 MPH is a panel-mounted gauge designed for 12/24V systems. It requires an 85mm hole with 55mm behind-panel clearance. The unit includes red and yellow backlights for visibility in varied lighting. The GPS antenna should be secured outdoors or behind a windscreen with a clear sky view. This model favors smaller vessels or skis where 0-60 MPH is the needed range and quick satellite lock.
Best for: Small ski boats and jet skis that need a straightforward 0-60 MPH readout with simple wiring. Better for those who want a compact, quick-install gauge and a clear backlit display. Caution: Ensure proper antenna placement to avoid signal loss; do not cut the antenna cable.
ELING 85mm GPS Speedometer 80 MPH With Course
This 85mm gauge emphasizes performance with a higher 80 MPH range and a course display. It requires an 85mm cutout with about 70mm behind the panel. The GPS antenna should be fixed in a flat position with black side upwards, ideally outdoors for a sky view. The device loads satellite data quickly—first lock in about 30 seconds, faster with a clear sky. It may need a full reconnection if signals are missing after power-up.
Best for: Jet skis and small boats needing accurate boat-speed and course data, particularly when higher speeds are common. Choose this if you value rapid satellite reacquisition. Caution: If you lose signal, retrace wiring and restart the unit.
MAIMEIMI GPS Speedometer 3-3/8″ 85mm TFT
MAIMEIMI presents a TFT screen GPS speedometer with 85mm gauge size. It supports 9–32V and offers three units: km/h, mph, and knots, with a display range that includes boat and auto applications. The unit is IP67 waterproof with anti-fog protection, designed for reliable marine operation. Installation requires an 85mm hole with about 55mm depth behind the panel.
Best for: Boaters seeking versatile unit conversion and a robust TFT display in a single gauge. Better for multi-vehicle use due to unit-switch capability. Caution: Verify the exact display range for your speed needs as data shows 0- something; confirm if mph is your preferred metric before installation.
ARTILAURA GPS Speedometer 85mm 7 Color
ARTILAURA’s 85mm GPS speedometer features seven color backlight options, including blue, red, green, teal, purple, white, and yellow. The bezel is 316L stainless steel, and the glass is anti-fog. It’s IP67 rated and designed for 0-80 MPH. This unit is intended for boats, cars, motorcycles, trucks, and off-road vehicles, with GPS data delivered directly from the satellite receiver, eliminating the need for a separate speed sensor.
Best for: Boaters who want aesthetic personalization and clear, bright color choices for readability in sun glare. Choose this if you appreciate a stainless-steel bezel and a wide 0-80 MPH range. Caution: The color setting requires interaction to switch modes; plan for initial setup if color preference matters for night visibility.
MAIMEIMI GPS Speedometer 3-3/8″ 85mm Black TFT
This MAIMEIMI model features a black-bezeled TFT screen and supports 9–32V operation. It uses the same easy 85mm installation with 55mm depth, and the GPS antenna needs a clear sky path for best results. The unit supports mph or knot readings and is designed for boats, marine vehicles, and other 9–32V systems.
Best for: Anyone seeking a robust, all-purpose 85mm gauge with a high-contrast display and multiple unit options. Better for owners who want consistent performance across different vehicle types. Caution: Ensure the panel has adequate behind-panel clearance and that the antenna remains unobstructed for optimal satellite reception.
Buying Guide: Key Considerations For Ski Boat GPS Speedometers
What size gauge fits my panel? Most 85mm (3-3/8″) gauges require an 85mm cutout with 55–70mm behind-panel clearance. Measure carefully and check your boat’s dashboard depth before drilling.
Which speed range do I need? If you primarily ski or tow, consider 0-60 or 0-80 MPH ranges for readability at higher speeds. For slower vessels, a 0-60 MPH model may suffice.
Do I need color backlighting? Color backlighting improves readability in bright sun or at night. Some models offer adjustable color options for quick visual identification on the water.
Is the GPS antenna placement important? Yes. Place the antenna outdoors or behind a windscreen with an unobstructed sky view. Avoid indoor corners or metal obstructions. Do not cut the antenna cable.
What units do I want? Most gauges offer mph, knots, and km/h. If you tow passengers in the U.S., mph and knots are common preferences. Some units switch units via simple wiring or menu access.
How reliable is installation? Most 12/24V gauges include mounting brackets or brackets and require basic wiring. Confirm that the back of the gauge has a dedicated socket for the antenna and power lines to simplify setup.
FAQ
- Q: Do GPS speedometers require a separate speed sensor? A: No. They derive speed from satellite data, not from hull-mounted sensors.
- Q: Will these gauges work on jet skis? A: Yes, many models are designed for marine watercraft and fit 85mm panel openings common on smaller boats and jet skis.
- Q: How long does it take for a GPS speedometer to lock on? A: Initial lock can take about 30 seconds; subsequent locks are faster with a clear sky view.
- Q: Can I install these gauges on vehicles other than boats? A: Many models support cars, trucks, and motorcycles in addition to marine use, thanks to wide voltage ranges and unit options.
- Q: Are there cautions about wiring? A: Yes—avoid cutting the GPS antenna cable, ensure proper grounding, and maintain clean, dry connections.
- Q: Do these gauges show trip or odometer data? A: Some models include odometer features, while others focus on current speed and course.
