[. . . ] Simply select the Salt TRAC setting and proceed to pump the search coil over the ground to be searched. The Salt setting will balance and then track to changes identically to the Ground setting only with an extended range, well into the conductive target area. Summary - The Ground TRAC setting is recommended for most searching conditions. Lock is used to hold a ground rejection setting that is first established in the Ground or Salt TRAC positions. Lock is recommended for areas that cause detector instability due to extreme ground peculiarities such as a lot of decomposing man made iron. Salt provides extended ground rejection range to compensate for conductive salt/alkali conditions. The Salt setting can ground cancel extreme enough to reduce sensitivity to low conducting metals, metals that appear low on the VDI scale. The Ground TRAC setting will not balance nor track into the nonferrous metal region. Despite this draw back the Salt setting still provides improved overall performance while operating in the salt/alkali ground condition. 17 Chapter 5 APOLLO 2 Controls Chapter 5 APOLLO 2 Controls Gain Control/ON-OFF With the GAIN control, you turn the instrument on/ off and select the signal strength. You might expect increased signal strength to always find more at greater depths. However, high ground mineralization will "bounce" the signal back and mask good targets. It is therefore necessary to ADJUST the GAIN to give you the maximum allowable GAIN without masking targets or overloading the circuit and at the same time allowing you to operate the detector with a constant faint threshold hum so that faint signals (deep or small targets) can be detected. In addition, any increase in GAIN adjustment should NOT BE at the expense of maintaining a smooth and constant THRESHOLD "hum". False signals, beeps and static from bits of mineralization, erratic behavior, and lapses in THRESHOLD all can be the result of running with too much GAIN. 19 Chapter 5 APOLLO 2 Controls Chapter 5 APOLLO 2 Controls Dual Control While operating in the Coin & Jewelry or Relic MODEs the Dual control operates as a DISC (discrimination ) control. DISC (Discrimination) is used to adjust the level of audio rejection against trash metals. The "P" (Preset) just below NICKEL is recommended for most general purpose searching. In this position, the detector will provide a reject response to most iron and light foil and respond to most valuables including jewelry. Positions lower than "P" (counterclockwise) provide less trash metal rejection, to the point of detecting virtually all types of common metals. Positions higher than "P" (clockwise) will reject more trash metals including aluminum pull tabs. even though the audio discriminator will signal with a reject (suppressed or broken) sound. Nickels and some jewelry will also be rejected with DISC settings much greater than "P". If when searching at the "P" position you feel you are digging too much trash, adjust DISC slightly clockwise and try again. Finding the lowest (furthest counterclockwise) position that eliminates the common trash metals in your area is important in order to find items of jewelry.
