Troublemaker's Tuesday - With Bushnell
The gun works on battery power, has a wide arc of coverage, and is remarkably accurate.
These have been used in the past to check the speed of thrown cricket or baseballs, to check the accuracy of car speedometers, or to see how fast trains move along the railway line.
Imaginative people will want to don a Village People outfit, speedgun motor cyclists on the open highway, then demand on-the-spot fines. The slight illegality of this may prove a hindrance, but I'm sure the motor cyclists will assist in setting things right.
Alternately one could set up outside the local police facility, speed clock the officers as they leave, and issue on-the-spot scoldings. That should go big-time...
You could point the speedgun at your tax refund and see how fast it disappears.
If you are Outraged of Salter's Point you can use the gun to monitor the speed of hoons in your road and then write accurate angry letters to the paper. You could also clock boats on the river and complain to the water police.
The uses are endless - come see the boys now and zap your way to the hearts of your neighbours.
