[. . . ] CS8SST OPERATING INSTRUCTIONS 2 CS 8 SST - RAPID GET YOU GOING INSTRUCTIONS SET-UP Assemble and adjust for length (Twist surplus lead around stem). Set the controls on the front panel as follows: · NOTCH (SELECT) Fully anti-clockwise · NOTCH (WIDTH) Fully anti-clockwise · DISC 9 o'clock · POWER 3 o'clock. The right hand LED on the front panel will illuminate for about one second indicating charged batteries. ) SEARCHING Keep the search head at a constant height, i. e. do not allow the head to swing higher above the ground at the right and left edges of your swing. [. . . ] These instruments have sophisticated programs that recognise the sensitivity setting and set the instrument for optimum performance. If the instrument gives a false reading, turn the control counter-clockwise as necessary to stabilise the instrument. As you turn the control counter-clockwise the maximum detection distance is reduced. This is similar to non-microprocessor controlled instruments, however, on this instrument the unit is designed to also increasingly desensitise itself to mineralised ground as you turn the control counter-clockwise. When the control is fully counter-clockwise there is zero discrimination. Zero discrimination allows the instrument to operate in the All Metal Motion Mode. There is no discrimination at all and all targets, except the ground are picked up. To give you an idea 9 10 where items fall out on the control iron will be rejected at about the 8 or 9 o'clock setting. Most pull-tabs will fall out at around the 2 or 3 o'clock position and screw caps are eliminated at the fully clockwise position. To accurately locate a target you can detune the instrument over the target by releasing then pressing the Pin-Point Button. It is very important to hold the search head still when detuning the instrument Failure to do so may produce confusing audio responses. 10 11 GENERAL HINTS Pin-Pointing When pinpointing it is important that the search head is held still while pushing in and holding the detune button. Hold the search head close but not directly over the suspected centre and while keeping the search head stationary, depress the button. Repeat this procedure until the response is a short audio blip and that will be the centre of the target. To verify the reliability of your target, it is a good practice to check it from another angle. Also, by holding the pinpoint button in and checking depth, you can check that you have correctly centred over the target. When the target reads the shallowest depth, that is the centre of the target. Always use care in retrieving the target so as not to damage your find. (i) The strongest signal will always be received when the object is directly beneath the centre of the head (see X in the diagram below). To pinpoint the find, stop the search head when you are directly over the target object, then move the search head through 900 and sweep again, thus forming a cross with the two sweeps as shown in the diagram. (ii) To `focus' the target signal still further raise the search head, retuning if necessary, and pass the search head over the object until only a faint signal is heard. The faint signal will then be occurring at a point X under the centre of the head (see diagram). More accurate pinpointing, particularly of deep buried objects can be achieved by finding the centre of the target object as described above and making a mental note of the position. Turning your detector through 900 and sweeping across the target again will give a second reading, accurately determining the centre of the object. [. . . ] Use a sharpened trowel or knife to cut a neat circle or triangle (do not remove the plug of earth entirely from the ground); extract the object; replace the soil and grass carefully and even you will have difficulty in finding the spot again. Bottle tops, silver paper and tin cans are the last thing you should throw away. Do yourself and the community a favour by taking the rusty iron and junk you find to the nearest litter bin. If you discover any live ammunition or any lethal objects such as an unexploded bomb or mine, do not touch it. [. . . ]
