Housing Requirements

DCI's FT5 wideband transmitter has the same design as earlier DigiTrak transmitter models and are compatible with existing drill housings that accommodate 15 in. (38.1 cm) DigiTrak transmitters.  The slots in the drill head must meet minimum length and width requirements and be correctly positioned. DCI’s transmitters require a minimum of three slots equally spaced around the circumference of the drill head for optimal signal emission and maximum battery life. Measure slot lengths on the inside of the drill head; slots must be at least 1.6 mm (1/16 in.) wide. DCI transmitters fit standard housings but may require a battery cap adapter in some cases.
