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.
ANTI-INTERFERENCE operation hints & tips
Being one of the largest coils available in the A.I. configuration this will provide great depth capabilities while 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.
