The UtiliGuard utility locating system from Ditch Witch uses Ambient Interference Measurement to automatically scan the surrounding area for noise, recommending the best frequency among its 70 options. To help users make more accurate locates of obstructed utilities, it measures distances (depth) both horizontally and vertically to the utility. It has a six-button, multi-language operator interface and a high-contrast LCD display to ensure visibility in all conditions, including direct sunlight. Dual outputs allow users to connect the transmitter to two utilities at once. It is Bluetooth-enabled to simplify data transfers. Its rugged housing with IP65 rating protects against dusty, dirty and wet conditions, and its transmitter and receiver battery life is 100 and 30 hours, respectively. 800/654-6481; www.ditchwitch.com.
