%X I find it disappointing that this paper appearing as it has in 1987 should distinguish different commercial types of TEM on the basis that each is only capable of certain types of loop geometry. The reasons given for the success of UTEM in detecting the P lens (as slim as the evidence may be), stem only from its use in the large fixed transmitter loop geometry. SIROTEM has been capable of operating in this particular geometry since 1983. Unless the paper is to be only of historical interest it should reach conclusions appropriate at the time of writing. The author has stated to me in writing "I feel that any high power impulse system fixed loop survey would have detected the P lens." (Staltari, 1987, pers. comm.). It is unfortunate that something to this effect was not included in the paper.
