DigiTrak Cable Transmitter System
The DigiTrak Cable Transmitter System is designed specifically for the following applications:
¾Borepaths with depths in excess of 50 ft (15 m).
¾Borepaths with lengths that require several days to drill.
¾Borepaths that do not allow walkover locating.
¾Borepaths in
The depth and locating range of the cable transmitter with a Mark III Receiver is approximately 140 ft (43 m), and it is approximately 100 ft (30 m) with a Mark I or Mark II Receiver. These depths are also depen- dent upon environmental conditions and characteristics of the housing. With the Cable Transmitter System it is also possible to obtain pitch and roll information at any depth. Depth and lateral location infor- mation is tracked using the DigiTrak Receiver in exactly the same manner as with regular DigiTrak Transmitters. The DigiTrak Receiver operator will not, however, obtain pitch, roll, or temperature informa- tion at the receiver because this information is sent directly to the remote display.
The Cable Transmitter System consists of four major components:
Cable Transmitter – This transmitter requires a special housing to accommodate the wire. The cable transmitter is inserted into the housing so that the cable extends through the back of the housing awaiting the first butt splice connection. A compression fitting is required to seal the cable transmitter from drilling fluid.
