With the Hangtimer you can time your jumps
Using tri-axis accelerometers, the Hangtimer is able to time how long you are in the air when jumping. It uses the same technology that NASA uses and costs $107 with shipping.
You can use the hangtimer for ski jumping, boarding, trampoline and anything else that you are in the air for moments at a time. If you are playing basketball you can now prove what your hangtime is when making that all important dunk.
Apart from counting hangtime, thats all. Nothing else is really achieved by this device except a few bragging rights that you were in the air for 10 seconds when going over that ramp.
