Features:

This product is based on GPS module data, mainly used for outdoor moving objects piggyback speed measurement, wide application scenarios, simple operation and easy to use.

1, This product has a built-in lithium battery, a full charge can be used continuously for 4 hours.

2, This product can provide you with the following data.

Fastest speed (data will be locked)

Real time speed (updated in real time)

Number of GPS satellites

Number of GPS telegrams

Specifications:

Size:67x33x21mm

Weight:43.5g

How to use:

1, the speedometer will be placed in the test object, installed firmly, GPS module up, and can not have metal objects to cover, turn on the power switch, wait for the GPS search star, when the number of satellites reached 7 or more, that is, you can start speed measurement. When the number of satellites reaches 7 or more, you can start to measure the speed. It takes about 3 minutes or more to search for the first time in a new place. (The higher the number of satellites, the more accurate the test data)

2, The product is equipped with type-c charging interface, red light is on when charging, blue light is on when fully charged.

This product has no data storage function, when the second speed measurement need to reset the data, based on the characteristics of the GPS will appear data drift and other phenomena, the data will not be zero after clearing, in addition, after the power on the device began to work, the instantaneous movement, will also lead to changes in the data.

(1) After taking a speed test, please switch off the device and wait for about 1 minute for the data to become single digits, then you can take another speed test.

(2) After taking a speed test, switch off the unit, press the reset button several times, then switch it on and wait for the data to change to a single digit before taking another speed test.

Package Includes:

GPS tachymeter * 1
