    Have developed a Metal Detector to use a DD ( double D design) coil in ground searching for metal now I need to implement the use of Mono coil into the Electronics circuit The Metal Detector uses Tx and Rx at the same time so I am looking for information on how to implement the use of the Mono coil ( like when using the telephone you have a constant 2 way ability without interference)

    A single coil will always be 'on' so to speak. You will detect changes in its inductance value due to nearby metal objects by the changes introduced into the circuit by the variations of the coils inductance.
