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. These coils are very robust and can last well throughout the prospecting seasons and with the replaceable skid plate there is no need to worry if you are scraping the rough ground as these can be easily replaced.

These coils are more suited to the open prospecting fields where the undergrowth and rocks are do not hinder a full sweep pattern

Available in:
1. DD PRO
2. GOLDSTALKER MONO
3. Anti-Interference

See the coil specs chart for more information on this product.

DD PRO operation hints & tips
Providing a large detecting magnetic field will ultimately help with depth. This is where this coil can help you recover deep targets. By swinging slow and overlapping by at least a third of a coil you will ensure the ground is searched thoroughly. Best suited to open detecting fields you can cover a lot of ground when you use this sized coil. It has good ability to see the smaller targets which are close to the surface. For example a 0.2gram target can be clearly heard at around 3 inches in ground with suitable ground conditions. This DD PRO will be perfect for the mild to high mineralisation areas where the Mono coils can be not so suitable.

At the front edge of the coil, about 1 inch towards the centre is where the sweet spot is. This sweet spot, once you get used to it will allow for accurate pinpointing on the smaller targets which have a clear response. The more broad deep signals will be more apparent more towards the centre of the coil.

GOLDSTALKER MONO operation hints & tips
With its large ground coverage, excellent depth capabilities and new lightweight design the 18” round GOLDSTALKER mono is a great choice for searching out the gold! With this new design the coils ability has been improved not only by the weight but with its stability and depth capability. The smoother the threshold the easier it is to hear those deep faint targets and the more likely you can encounter targets at depth. This coil may struggle to hear the 0.2 and 0.1 gram targets unless they are within the tip inch of the surface but that is not what the coil is best suited for. This coil has better ability to hunt deep and recover the larger targets. It is also a perfect option for the larger open fields where there is minimal obstacles so would consider this coil as a perfect tool to go hunting for the patches. Remember to overlap your swings by at least half a coil and keep the swing low and slow.

ANTI-INTERFERENCE operation hints & tips
Being one of the largest coils available in the A.I. configuration this will provide great depth capabilities whilst still eliminating any external interference produced by things like power lines, electric fences and mobile towers. It will have a broad search pattern and provide good sensitivity to targets ranging from 0.2gram close to the surface to large targets at depth. Although it does not have the sensitivity and depth of its DD and mono counterparts it will still enable the prospector to get into areas where these other coils become very unstable. If you do not wish to use the cancel function on the later detectors where you can experience a loss of depth you can be ensured of good ground penetration with this coil. Suited mainly to the more open terrain it is best handles with a swing assistance like a bungee cable and a slow swing speed will allow the magnetic field penetrate deep.

Strengths:

• Large ground coverage
• Deep penetration
• Very robust design
• Good sensitivity to larger targets at depth
• Great patch finder
• GOLDSTALKER MONO is very lightweight

Weakness:

• Heavy coil for all day use (DD and A.I. only)
• Loses sensitivity to small targets at depth
• Not the best choice for overgrown/rocky areas

Applicable metal detectors:

• Minelab SD Series
• Minelab GP Series
• Minelab GPX series
