The clock is 5″ high character with 5 digits,supports countdown/up function. When it counts up, it can count up to 9 hours 59 minutes 59 seconds from 0:00:00 and when countdown it counts from 9 hours 59 minutes 59 seconds to 0 hours 59 minutes 59 seconds. Besides, you can start a countdown or a count up timing at any time between 0:00:00 and 9:59:59 in hours minutes seconds.
On this clock, we are using a more light-weighed tripod and the size is very small. It is quite nice when you set the tripod height below 1.5 meters(around 3.3 ft). When the tripod is folded, it’s only around 0.66 meter long and the weight is only around 1 kilo gram. Plus the clock weight, the total weight is around 2.5 kilo grams. So, you can easily carry it anywhere.(But, please do fasten the tripod legs during the running events if the wind is too heavy, don’t let the wind blow it down).
Another demand from our customers is they usually want a battery to power up this clock. We also think it as a must. So, besides the regular AC-DC power adapter(100-240VAC input, 12VDC output, with one meter long power cord), you can also use a battery to power up the clock. Due to the forbidden policy on battery, we don’t provide battery. A specs reference may be helpful for you. A 6800MAH battery can power up this clock around 2-4 hours. The cable that connects battery and the clock must be with a connector 2.1/5.5mm so that it can plug to our clock.

The digits are made by red color LEDs, which can work for 100,000 hours. The time chip has a tolerance of 2-3 minutes per year.
