The small 10 x 5” (250 x 125mm) coils are most commonly used for mullock heap hunting, areas of heavy over growth hunting and just searching for the finer gold on the patch. With excellent sensitivity and good depth capabilities it is an excellent choice for any detector operator. Their size gives a relatively small view of the ground but it is because of this that they are most suited to the smaller targets.

The 15” All Terrain coil has been a very successful coil for a wide variety of detectors. Mainly made to match the coin & relic machines, it has also been made for the entry level VLF gold machines namely the XT series and Eureka Gold. Due to the size of this coil, it can increase the depth performance up to 30% over the standard coil without reducing the sensitivity a great deal.

Weighs only 417 grams. Weights are taken as an average and include skid plate.

If you are in need of a deep searcher with excellent ground coverage then this size of coil will fit your requirements. Designed especially for the deep ground without losing too much sensitivity these coils have provided many options for prospectors with a lot of ground to cover. They allow the user to feel confident they are looking deep into the ground, whilst not having to drag the coil due to being too heavy and cumbersome.

18.5×12 inch Mono (470x300mm) – 795 grams

The 17 x 11” Elliptical coil has and is proving to be a fantastic all round performing coil. Released to provide a well balanced coil which provides the prospector with good maneuverability in tight areas it continues to be a preferred coil of use for a lot of operators.

With its elliptical shape it 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.

These coils were originally produced in the Anti-Interference (A.I.) configuration for the SALT LAKES in Western Australia but have become a great search tool for many areas around the world. We produce these mainly in the A.I. configuration but also as the DD. We find that a mono coil of this size is too big and will be very noisy. They have excellent depth capabilities which is why they are such good patch finders but their sensitivity to smaller targets, 1-2 grams and below, is greatly reduced.

The 40 x 20 coils do take a little time to set-up and get right in regards to towing / dragging but their performance is very good once achieved. The main thing to remember is to protect the cable from any snags or pulls from low lying bushes and rocks. Clear, flat terrain is best.

For prospectors who don’t mind digging deep holes!

Good depth capabilities plus sensitivity to find sub-gram targets close to the surface.

Covering a lot of ground quickly, it offers excellent manoeuvrability through overgrown areas and between large rocks, as well as being waterproof (mono only).

This coil has been an excellent addition to the range of products we offer. This is a unique design as it is fully water proof and one of only a few fully water proof coils we produce. The coil is potted with epoxy resin which holds all the windings secure and provide its water proof ability.

The 6″ X-TERRA utilises the Minelab VFLEX technology and is the perfect choice for trashy areas, giving excellent target separation and stability.

We are the only global after market manufacturer of fully approved Minelab X-TERRA coils utilising the VFLEX technology.

The 14” (350mm) coil is one of the best all-round performing products Coiltek has produced. With a combined advantage of excellent depth and sensitivity it has outstanding performance ability in the majority of goldfields around the world. Being an extremely robust coil it has the capability of lasting many seasons in the field which will make this coil a primary choice when prospecting.

This lightweight coil provides excellent stability, heightened sensitivity, great ground coverage, and maximum depth capabilities with superb ground penetration.

Introducing COILTEK’s new range of coils. They incorporate a new winding innovation which optimises the transmit and receive signals, therefore improving depth and sensitivity when compared to the standard wound coils available.

Weighing in at only 1110g, this large coil is very lightweight for its size and makes light work of searching large areas. It offers a good stable threshold in most circumstances plus the best depth capabilities of the round coils. Although suited to larger, deeper targets, it still impresses with its sensitivity; during testing it found 2g pieces at approx 25cm deep.
