The 10×5 inch Joey coil is another best selling coil! Excellent on exposed bedrock or hunting around rocky or brushy areas. Probably the most sensitive Mono searchcoils for small gold nuggets. Most serious nugget hunters have this searchcoil in their searchcoil arsenal.
I personally have found nuggets down to 0.5 Grains in size with this coil on the GP and GPX series Minelab metal detectors.
Weight 16 ounces!
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.
Smaller coil = increased sensitivity to smaller targets.
They are also excellent for maneuverability as they are very light weight and can either be used as a detecting coil or locating coil.
MONO Operation hints & tips:
The small mono has a benefit over most mono coils due to its size. This comes in the way of heightened sensitivity and less susceptibility to mineralisation. Again, the small field being produced reduces the ground noise to some degree however the coil is still a mono coil and this can cause some mineralised conditions to create ground balance issues. Having said that, the target response of this coil is sharp and clear so most likely the targets will be easily heard if within the range of the coils magnetic field.
Being a mono it has the windings around the perimeter of the coil so pinpointing can be done by either using the tip of the coil or tilting the coil to vertical and using the outer edge. You will notice that the outer edge is sensitive all around the coil. When swinging this coil you will need to overlap your swings by approximately half the coil length to be thorough and having a slow swing speed will ensure you hear the very tiny targets.
- Very light weight for all day use
- Ultra sensitive to small, closer to the surface targets
- Good depth capabilities for a small coil
- Very maneuverable in tight areas
- Robust design
- Easily carried in a backpack for use as a pinpoint coil
