As with any purchase, buying large numbers, or wholesale, would always certainly be a cheaper way in acquiring your products. Depending on where you get your items, the wholesale price of your radar detectors may change based on product type, location of the source, and the number of detector units you allot to order for. There are also sellers who "dropship", they take your bulk orders, and directly deliver them to your specific location; this proves to be very convenient when you're in a position of being in a central office, and make the wholesale orders by phone, and distribute them to stores in varying locations. Resellers often take advantage of the source's dropshipping option, since it is more hassle-free and economical. Similar to all implemented laws, speed limits are there for our own well-being, and also for the protection of those we may inadvertently smack into due to the lack of attention to how fast we're driving. Regardless of the dire consequences, we go on in rushing in our vehicles, speeding at every possible chance to quickly arrive at our destination. There are times, while in the middle of it all, we do get caught. When a police officer readies to shoot his radar gun, he can accurately measure your car's speed along a distance of approximately 1/5 of a mile. Police radars generally make use of four frequencies, the X band at 10-11 GHz, K band at 24GHz, Ka-wideband at 32-36GHz, and lately, the Ka super wideband, which can reach frequencies of 33.4 to 36 GHz. Radars emit a continuous pulse of radio signals which, when obstructed by an object in motion, changes it's frequency according to the speed and direction of the vehicle. Speed is then calculated by the detector, factoring the amount of time it takes for two comparable pulses to reach the receiver of the radar gun after the signal bounces off the moving vehicle.
