One of the biggest advantages of the Seek Tech locating equipment is its ability to identify / trace a target utility with four different key indicators. What makes them all unique is the way they are calculated. Each indicator is calculated by using a different combination of antennas or calculations based on multiple readings. What this does in a sense is give the locator the built in “second, third and even fourth” opinion as to the location of the target utility. The problem with stating a certain utility should be within a certain range is that there are too many variables that the locator cannot control. The type and quality of the conductor, the soil conditions, and any interference in the immediate area can all affect the quality of a locate. What one should be looking for is the agreement of these indicators rather than a specified range for each on an individual basis. If I can get my balance arrows, my trace line, signal strength and proximity to all agree on a specific location I have the highest degree of confidence that I have made a good locate. The fewer indicators that I have in agreement, the more distortion that is present and this is an indicator that I need to change some of the things I can control, like improving my ground or changing my frequency.
