[attachment=IMG_2247.JPG] Diggers,I have been working on a privy detector for 5 years now and have built pulse induction, ground conductivity, earth resistivity and thermal units. Unfortunately you can not beat GPR. Working on my third GPR system. The first one worked but detected other objects above ground as well because of the unshielded antenna. Second one worked well to about 10 feet but had noise problems and reflection issues. Both could find pits but the third one is using a state of art antenna/reflector and should see to 12 feet with very good resolution. The best part of the unit is I am trying to build it for less than 30 percent of a commercial system; making it affordable. Will keep you all posted and send scans of dug privies and un-dug privies.
