Let say you live in the city, and you want to get some practice time with your hand gun. Now discharging a firearm with in the CITY LIMITS of most American Cities is ILLEGAL. Not to mention it pisses off your neighbors. Well have you ever thought of a LASER BASED digital shooting range?
This is how it works. You have a cartridge that contains a LASER, a switch were the primer is located. When the hammer falls the LASER is fired with a brief flash. You have a target made up of very small photo receptors and some limited computational capacity. This target is attached to your laptop with displays the target and the photo receptors that were activated by the LASER beam from the cartridge that was in the weapon. This gives you an instant reading of where your theoretical bullet would have impacted on the target had you been firing live ammunition.
For the the firing of rifles you can even program in range, giving you bullet drop and wind drift.
SO NOW YOU CAN GO OUT IN YOUR BACK YARD AND BLAZE AWAY AT YOUR HEARTS CONTENT, AND NOT UPSET THE LAW OR YOUR NEIGHBORS, not to mention save a bundle of cash on buying ammunition. A good LASER cartridge is going to run about $100.00 and the target and computer lash up and software another $400 to $500.
