after a gully washer rain.Through the years there should be
some type of seepage leaving a sunken place.I have found
old milk wells that way.Just my two cents.HH Wolfbite
gldhntr said:taking readings with a ground resistivity unit using two probes will show you caves/mines/tunnels...depending on how you set it up you can hit on them to around 100-125 feet deep...will not work in very sandy soil or areas of high quartz mineralization..also will not read through bricks and a few other items although you can drive the probes through blacktop pavement and still get perfect readings......carl moreland had plans for one that could be built for around 150 bucks at one time....maybe check his website or email him....gldhntr
