The Rex (Receiver + Xmitter) multifrequency locator from Schonstedt Instrument is less than 2 inches thick and weighs less than 3 pounds. The pistol-grip receiver extends for greater sensitivity and retracts for easier carrying and storage. At slightly over 7 pounds, the entire system fits easily into a custom shoulder bag.
