CoilTek C01-0004 11" Anti-Interference Round Coil (275 mm)
This size is the most commonly used coil for prospecting, mainly due to the new detectors being released with a coil of this size. Many prospectors enjoy using a coil of this size because it gives reasonable ground coverage, has good sensitivity, has average depth capabilities and is relatively light weight. You will find the coil easy to maneuver and it is quite easy to pinpoint with.
Anti-Interference (A.I.) operation hints & tips
These coils have been designed to cancel out the effect of external interference. This can come from power lines, electric fences and the spread of the metro area just to name a few. Their performance is very good compared to the DD coil and we estimate their ability to only be approximately 5% behind the DD’s depth. The sensitivity can sometimes match the DD’s and therefore you can be confident when swinging an A.I. that you will have the chance to get the smaller targets and the larger ones. The main sensitive area of these coils is directly down the centre which is similar to the DD. Approximately 1 inch in from the tip of the coil will be the best area for pinpointing and this can help increase your target retrieval time. Their ability in mild to heavy mineralised areas can sometimes become noisy as they tend to behave like a monoloop coil as they struggle with the ground change so having a slow swing will help minimise the noise.
