{ "item_title" : "Police Radar Basics", "item_author" : [" Donald Sawicki "], "item_description" : "Easy to understand and fully illustrated description of everything every driver, and the police, should know about traffic speed radar. Police radars are not just point (at target) and click (transmit) devices. There are some basic setup limitations and operating procedures that must be observed. Too often procedures are not properly followed in order to save a little time or hide from motorists, resulting in speed errors. This book details radar types and operating modes, proper use and test (including the widely misunderstood tuning fork test), limitations, calibration records, and how Doppler radar works. Anyone that operates a police radar should already understand everything presented. However, far too many operators don't remember or don't use what they were taught in radar training.", "item_img_path" : "https://covers4.booksamillion.com/covers/bam/1/50/897/551/1508975515_b.jpg", "price_data" : { "retail_price" : "19.95", "online_price" : "19.95", "our_price" : "19.95", "club_price" : "19.95", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
