The 17T4 beacon works with bothDitch Witch® and Subsite®TKQ and TK Recon Series locators. The beacon includes a set of rubber bumpers. It performs well in different conditions and can track shallow or deep bores. The beacon works at 4 different frequencies - 1.5kHz, 12kHz, 20kHz and 29kHz by sending beacon data to a locating system and the remote display typically mounted on the drilling drill.
