Operating instructions

power on or the detector will not function correctly. If a problem is encountered turn the

detector off to reset the microprocessor.

When you first begin using the CS 8 SST it is suggested that you set the Discriminate

control, Notch Select and Notch Width fully counter-clockwise. This turns the notch facility

off. To set the Notch Select, the Discriminate control must be at a lower setting than the

Notch Select control (set the Discriminate control to 9 o’ clock initially). As an example, set

the unit to reject iron and pull-tabs but still pick up nickel and coins of other materials: first,

turn the Discriminate control clockwise while moving the search head over iron. A

screwdriver or your digging tool will work well. Increase the Discriminate control until the

unit no longer responds over iron. Next, set the Notch Width control to 12 o’clock- position.

Now, while moving the search head over a pull-tab, turn the Notch Select control clockwise

until the unit no longer responds. To check, move the search head over the coin and it should

respond. The LED should also indicate a good target, eg A to G on the lower scale.

Adjust the lower stem so that, with the unit in your hand and your arm extended towards the

ground, the search head is just off the surface. Using a slow sweeping motion, swing the

detector from side to side as you walk forward at a very slow pace. The slower you proceed

the more thoroughly you will cover the search area. Try to maintain the search head as close

to the ground as you can without actually touching the ground. You should concentrate to

maintain this height off the ground, particularly at the end of the swing where the tendency is

to raise the search head before starting the swing back in the other direction.

The CS 8 SST will indicate a target with an audible identifying tone as well as lock on a LED.

Sometimes it helps to read a target from more than one direction. Turn 90 degrees over the

suspected target and sweep again. Sometimes the reading will change indicating that the first

reading may be false. Practice will make you more proficient at this technique. In most cases

good targets read the same from any direction and bad targets tend to change.

THE CONTROLS AND WHAT THEY DO

POWER ON/OFF SENSITIVITY

This control turns the instrument on and off, and controls the motion mode sensitivity. Fully

clockwise is the most sensitive position. 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.

DISCRIMINATION

This is a full range discrimination control. When the control is fully counter-clockwise there

is zero discrimination. When fully clockwise the instrument rejects zinc and screw caps. 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
