A while ago the metal detecting forums were all agog with details of the tests of the Blisstool LTC64 V3 and how powerful it seems to be. It apparently reaches depths that other machines cannot, while being cheaper than the equivalent Minelab GPX 5000 machines. Nowadays when most of the more accessible "productive" sites have been "hammered" depth has become even more of an obsession amongst detectorists, the easiest way to accumulate a personal collection or artefacts now is to get them from deeper and deeper layers of the searched site (Readers may remember that this is an issue that both this writer and heritage action have been urging that the PAS raise with policy makers, there is no sign that they actually have so). Anyhow Heritage Action have again raised the alarm about the proliferation of cheaper "depth advantage" machines ('A second open letter to the Heritage Forum'). No reaction from the heritage "professionals" but an interesting one from the metal detectorists. Over on the Detecting Wales forum the thread “Blisstool LTC64 V3 The Worlds Deepest Detector?” suddenly disappeared. It turns out that the thread had been hidden by the site administrator and details can only be exchanged through the forum's private mail system. Just in case somebody's looking eh? Just in case somebody's looking and reach a conclusion about the way artefact hunting is going these days which detectorists would rather keep unsaid.
