In terms of noise, sometimes noise frequency is close to the frequency of the transmitter. Choosing between transmitters of different frequencies can increase probability of avoiding noise frequency. Then why not set two frequencies in a transmitter? In fact, this idea is feasible, but in that way, the antenna of the transmitter will not be under optimal parameter, which will cause a loss of signal strength for the transmitter. For that reason, to have two transmitters of different frequencies is a better option.

A locating system’s depth accuracy is mainly relevant to the quality of earth and the noise. Normally, the permeability of earth is very close to that of air, so if a system is accurate on the ground, it is accurate underground. Based on this fact, all the locating systems do a 3-meter calibration on the ground. However, if there is interference source underground, such as sea water, cables, metal pipelines and conductive minerals, depth accuracy will be interfered underground.

First of all, pitch and roll of a transmitter is calculated through the earth’s gravitational field, which makes the signal free from disturbances from the earth’s magnetic field. Second, pitch and roll information is delivered in a form of digital signal, which is rarely mistaken by the receiver. These signals are transmitted repeatedly, so mistaken information will immediately be replaced by correct information. Therefore, pitch and roll signal should be trusted even when a system is in an environment of interference.
Locating systems calculate a transmitter’s location through the shape and strength of the magnetic field formed by the transmitter. Any factor that changes the shape and strength is considered noise, which will alter the calculation of the transmitter’s location and depth. Noise can be divided into two types: passive noise and active noise. Active noise: conducts with current, which can form a magnetic field to interfere with a transmitter’s magnetic field. These items include cable lines, optical cable, high voltage wire, railway, etc. Passive noise: the source of disturbance itself does not form a magnetic field, but when the magnetic field of the transmitter passes by, it changes the shape and strength of the magnetic field. These items include metal pipelines, reinforced concrete structures, culvert, sea water, etc.
Depending on your financial situation, you should choose the locator suited for you. However, the higher the depth-range, the better the locator. A system of 18 meters may be able to detect 18 meters deep in an ideal environment, but it may only detect 10 meters if there is noise in construction site. In the same environment, a system of 25 meters may only detect 15 meters due to noise. Noise can also affect radio usage. In a quiet room there are two radios, one of which can be heard from 3 meters, while the other can be heard from 10 meters. However, if you open the window and allow noise from outside to interfere, the first radio may only be heard from 1 meter, while the other can still be heard from 5 meters.
All locators come with a depth index, which is the maximum depth the locator can detect in an ideal environment. What is the formal definition of depth? The formal definition of maximum depth is the maximum distance between the locator and the transmitter while receiving pitch and roll signal.
