PI machines send very rapid intermitant pules of energy through the coil. the power is built up then released by cutting off the volts to the search head The high power of these machine is last during the building up and shutting down process so there no real advantage over say a multi frequency machine (idea for use on the beach) PI machines are unbeatable on a beach free from Iron. They can detect 12inch plus on some beaches but like you said with no disc to speak of you ,ll soon get fed up of digging deep iron. also recovery speeds can be very slow If i wanted a good beach detector id be looking for a multi frequency machine hope this helps all the best Phil |
