This company claims to have the strongest signal strength and range available among pig tracking transmitters. The user need only install the transmitters inside the pig, launch the device, and await a signal from either a non-intrusive pig tracking sensor or an optional locating wand. The systems can be used with 2-inch to 72 inches pipe inside diameters in onshore and offshore transmission lines, gathering lines, water and waste, and a variety of industrial processes and utility piping.
