[QUOTE="Heatho, post: 424328, member: 487"] The Equinox manual actually states that in some detecting situations a single frequency might be better. Copy from the Nox manual: [i]Single Frequency Operation Using a single frequency may have a slight advantage over multifrequency in certain detecting situations. For example; if you were searching only for larger high conductive targets located at great depth, using 5 kHz may give an advantage. Similarly, if you were hunting only for very fine gold jewellery at a shallow depth, then 20 kHz* or 40 kHz* may give better results in some detecting environments, such as at a beach on the dry sand. In some noisy environments (e.g. high Electromagnetic Interference, where Noise Cancel is not fully effective), a single frequency may pick up less noise than Multi will, however maximum target sensitivity over a wide range of targets will be reduced.[/i] I haven't found this situation yet, some targets I've found at the limit of detection I have actually switched to 5khz and 10khz before digging it up and the targets disappeared, then switch back to multi and the target was there again, these were very borderline faint signals. In my experience with the Nox multi detects deeper with it in the different soils around my area. [/QUOTE]
