changing drill bits or sondes thus the process of orienting the sonde is not necessary each time the drill head is worked on it is expected that once assembled the drill heads are typically dedicated to a certain type of set up and adjustments are not performed frequently it is therefore beneficial that one sonde can easily be adapted to any known drill head set up aside from the variations in drill head physical characteristics and physical variations of sondes there are two basic types of sondes a battery powered sonde and a wire line powered sonde fig1 illustrates the sonde mounting of the present disclosure adapted for use with a wireline sonde in fig1 the wire line is threaded through the drill string from the ground surface to the drill head in any known manner present drill head configurations provide for a wire routing path that allows the wireline to be connected to a sonde this routing generally involves a strain relief plug 74 strain relief 76 and tapped hole 150 as illustrated in fig1 the tapped hole 150 projects from one end of the main housing 100 into the cavity 102 when a battery powered sonde is used there is no need for anything to project through this hole so a plug 72 shown in fig4 is installed however when a wireline sonde is used this plug 72 is removed and a similar plug.
