SP-GPS95 Universal Digital GPS Speedometer Waterproof. Displays Speed(MPH/KMH), Distance Traveled and Time - Suitable for ATV

The Waterproof Digital GPS Speedometer is a versatile device that can be used in various vehicles, including ATV, UTV, marine, boats, motorcycles, and automobiles. It features a backlight for easy visibility in low light conditions, making it suitable for night time rides. One of the key features of this speedometer is its built-in GPS antenna, which allows it to accurately calculate and display the speed based on the satellite signal. However, some customers have expressed dissatisfaction with the GPS signal strength, stating that it is rather poor and may require a separate external GPS antenna for better performance. The installation of the speedometer is reported to be relatively easy, with a wiring harness included. The device requires a hole with a diameter of 61mm for installation. One common concern raised by customers is the difficulty of changing the speed units from kilometers per hour (kph) to miles per hour (mph). According to the manufacturer's instructions, this can be done by toggling to the distance settings in the menu and holding down the SET button until the units start blinking. However, some users have found this process confusing and have requested clearer instructions for changing the units. In terms of display visibility, customers have reported mixed experiences. While some find the LCD display easy to read, others have had difficulties seeing it clearly in bright sunlight, even with different display color options. This could potentially be a safety concern, as it may require taking one's eyes off the road for more than 2 seconds to check the speed. In terms of size, the speedometer is stated to have a diameter of 57mm (2 1/4 inches), which may not fit all gauge pods designed for 52mm (2 1/8 inches) gauges. This may require enlarging the hole or finding a different size gauge pod. Overall, the Waterproof Digital GPS Speedometer offers a convenient and accurate way to measure speed in various vehicles. However, there are some concerns regarding the GPS signal strength, unit calibration instructions, and display visibility. Potential buyers should Consider these factors before making a purchase.
