receptor stem 44 the receptor stem 44 may be attached to the drill pipe 18 by engaging a top thread of the drill pipe 18 with a corresponding bottom thread of the receptor stem 44 a receiver 42 is attached to the receptor stem 44 and in communication with a display 46 that is viewable by an operator in practice the electrical inclination sensor 38 determines the inclination of the stem 21 of the housing running and jet tool 16 which corresponds to the inclination of the entire drill assembly 10 the inclination sensor 38 then communicates the inclination data to the transmitter 40 next the transmitter 40 transmits an inclination data signal upward in a pulse through the mud surrounding the stem 21 and the drill pipe 18 to the receptor stem 44 at the receptor stem 44 the receiver 42 receives the signal and communicates the inclination data to the display 46 in certain embodiments the inclination data is generated constantly by the electrical inclination sensor 38 and transmitted in real time to the receiver 42 thus the operator receives continuous real time data about the inclination of the drill assembly 10 throughout the primary jetting process in an example of acoustic data transmission as shown in fig7 a and 7b the electrical inclination sensor 38 is attached to an outer face of the low pressure housing member 12 likewise the transmitter 40 is attached to the outer surface of the low pressure housing member 12 and is connected to the electrical inclination sensor 38 by a wire not shown receiver 42.
