Things to Remember
	*A good circuit* - Has low resistance to the flow of electrical current through the target utility. The utility, the earth, the ground rod and all of their connection points contribute to the resistance to overall current flow. Actions taken to lower any resistance will help increase current flow. Grounding - Make sure that both your transmitter and the far end of insulated lines are well grounded. These connection points "close the loop" to complete your circuit. Type of Soil/Moisture Content of Soil - Moist, clay soil is highly conductive; dry, sandy soil is not. Conductivity of Target line - Continuously metallic lines are good conductors, non-metallic utilities do not conduct. Continuity of Target Line - Insulators or gaskets between sections can impede or block current flow, especially at lower frequencies. Common Bonding of multiple utilities - This creates many paths for current to flow. It confuses the locate and robs current flow from the target line. Presence of other lines - Adjacent conductors can draw current off target line even if they are not directly bonded. More current makes locating easier and more accurate - The downside to using the maximum power setting is shorter battery life. To maximize both accuracy and battery life, a good rule of thumb is to set the transmitter's output to the point where you have a strong, steady and clear signal over the distance you need to locate.
