I need GPR equipment to locate plastic and metal pipes down to 1/2 inch diameter, with computer and GPS. What brand to buy?
Without knowing the specifics of the survey, here is my opinion. I really doubt the GPR equipment will find plastic pipes. They will not change the electrical resistivity of the ground like metal pipes would. Also, GPR is rather long wavelength so again, locating a 1/2 pipe would be fairly hard, unless you make a dense 3D grid across the area. Metal pipes are very easy. Purchase a 100$ metal detector instead of a ten thousand dollar+ GPR and computer.
