14HOLDING THE DETECTOR

SWEEPING THE COIL 15

To hold the detector, thread your arm through the armrest and strap. Grasp the handle of the detector and rest your forearm in the armrest.

Your elbow should sit just above the top of the armrest. Lightly tighten the velcro strap and secure it around your arm.

The correct position of armrest and length of shaft should allow you to swing the coil in front of your body without any uncomfortable stretching or stooping.

To adjust the length of the shafts, undo the twistlocks, compress the spring pins of the shafts and move them up or down to suit. Once all shafts are clipped into position, rotate twistlocks clockwise onto the shafts until they are firmly clamped

(Shaft Assembly, pg. 5).

To adjust the position of the armrest remove the armrest screw and move the armrest and stand to the desired position

(Armrest Assembly, pg. 6).

Once outside, practise sweeping the coil over the ground in a side-to-side motion, while walking forward slowly. Slightly overlap the previous sweep to ensure full ground coverage. An average sweep speed is three seconds from left to right to left.

Try sweeping the coil faster in Coin & Treasure Mode for improved target detection and identification.

Try sweeping the coil slower in Prospecting Mode for improved target detection and separation from ground mineralisation signals.

It is important to keep the coil close and parallel to the ground at all times. This will increase detection depth and response to small objects. Avoid excessive brushing of the coil on the ground, as this may result in false signals and inaccurate Target ID’s.

A variation in coil height at the end of each swing may also cause confusing sounds and reduce detection depth.

Think of the detector as an extension of your arm. It should be straight with your forearm and feel light and comfortable when you pick it up.
