Coiltek 17" x 11" Goldhunting Anti-Interference Coil
For the Minelab SD, GP, and GPX series detectors
The Goldhunting Anti-Interference series of 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 urban areas just to name a few. Their performance is very good compared to the similar sized DD coil and we estimate their depth ability be very slightly less than a similar sized DD coil. The sensitivity can sometimes match the DD’s and therefore you can be confident when swinging an A.I.coil 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 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. The other benefit with this coil configuration is that it will work perfectly well with the Discrimination/Iron Reject settings on the Minelab machines so they add value to your detecting experience no matter where you are.
With its elliptical shape the 17" x 11" Anti-Interference coil provides good coverage over the ground and the ability to search in and around the terrain and is also complemented in having excellent depth and sensitivity capabilities. When nugget hunting it can pick up the sub gram pieces and ensure that pinpointing is made easy with the tip of the coil. Relic hunters love this one too, as it finds those relics that have sunk to depths not normally reached by a normal detector and coil combination in those high EMI areas.
It has a centre mount shaft mounting position with an 8mm nylon nut and bolt for extra strength. Also, being of the solid coil design it can help when grasses are long to push down close to the ground and not be hindered by sticks and the like stopping the swing. This coil is a great choice for excellent overall performance and balance and continues to find gold and relics in many of the world’s gold prospecting regions.

Anti-Interference (AI) operation hints & tips
To say that the AI coils are sleepers is a huge understatement. We have heard that these coils are proving to be a coil of choice in a lot of areas around the world as detecting areas become more susceptible to external interference. This interference comes from Electrical towers, mobile phone towers, electrical storms and other detectors. It is also prevalent around built up areas which are close to detecting sites. It will allow the operator to run with a smooth threshold when a DD or MONO coil is extremely noisy. Its performance ability is only just behind that of a DD PRO however it can sometimes become slightly noisy when the mineralization content increases. These coils are best run on the more mild ground but perform excellently when encountering external noise. These coils were designed for the SALT LAKES of Western Australia but continue to prove their ability in many fields around the world. These coils do not need to run in cancel mode on the newer detectors as the coil is doing the work of cutting out the interference. These are best run in DD mode and will also work well with the discrimination function. Sensitivity is excellent and depth is very good so this coil is a good choice for many hunting areas.
