Sports coaches use the stopwatch, we may seem very simple, but in fact it is not a simple thing, here talking about, which most people will not use it?

For example, in school, a class has 45 students, when we go to physical education, physical education teacher asked to run a race; Haha, the 45 students can not run one by one right? That's right, we can run with a couple of them, how many of the stops of our PE teacher can record the difference in running? This has to choose a multi-channel function of the to use, the most basic stopwatch on the market has two memory track number, and these two means that it can record the gap between the two players at the same time Every one, so understand it.

Currently there are often 2 to 500 on the market, the machine products have long met the requirements of the sports coaches, and that stopwatch can count how long? As far as I understand this multi-channel is generally 10 hours, 2 can actually record 24 hours, these are common, maybe your former physical education teachers are these types of 2 to 60?

How to operate these channels?
This left and right buttons on the stopwatch, click the left button will record a track, press the left button when the screen will pause to see the time spent recording the results, while the other did not pause, when we press Right when you see has been running time, when the second classmate is running we press the left button, which is suspended for us to record the game results, this data does not need to use the pen to record, but Automatic storage, physical education coaches only know the students to achieve the ultimate goal of the sequence, because the will be from the students' first grade to the last one to record the results of the competition results.
