I've been hunting an area where many years ago homes sat (1800's).  There is several areas where there was once gravel and shell drives, now covered with about 2-3 inches of soil.  We are finding several targets and coins in the gravel/shell mix.  Digging is tough and slow.  Can any one offer any magic or trick to make the digging easier?  Just thought I would ask.
