If probes don't work, witch for it....
best is a pair of brazing rods bent into an L, about 6" for hand and the rest out front. You can also put the bent hand portion in a short copper tube sleeve that acts like a bearing in your hands. Hold the rods parallel to the ground and pointing directly to your front - like holding 2 cowboy pistols. Walk the area in a grid pattern until the rods swing into each other. Mark the point where they crossed and keep moving around. If you're lucky you'll be able to outline the tank, mark the inlet line and the outlet. Same process can find the drain field legs.
A quick altenative is a pair of simple clothes hangers bent into the L....just be sure to hold very lightly, don't put them in a death grip. Easy way to check the witch is to try it over a known waterline....works on buried electric cable, too. /forums/images/graemlins/grin.gif
