[. . . ] If you can find a setting on the ground balance control where the ground noises go away, then you must leave the Gnd BalToggle on, and select a conductivity option. If you are not able to find a ground balance point, and the detector operates quietly without interference no matter where the control is set, it means that the ground is not mineralized enough to require ground balancing. This means the Pulsescan AMPHIBIAN circuitry can handle the ground without manual ground balancing, and the Gnd Bal toggle could be turned off. In this case there are two options - PulseScan AMPHIBIAN Owner's Guide Option # You may switch the toggle to Off. This eliminates the Ground Balance control, the Audio Tone feature, and the selectable conductivity feature allowing the Pulsescan AMPHIBIAN circuitry to handle the ground mineralization. Then set the Ground Balance as noted in Chart A Chart A Mandatory settings if you cannot find the ground balance point, and wish to activate the variable Audio Feature. # - If you have set the Pulse Delay at 10 uS, which is recommended for average size gold, set the Ground Balance control at approximately 8. # - If you have set the Pulse Delay midway, set the Ground Balance at approximately 6. # - If you have set the Pulse Delay at 25 uS, which is suggested for beaches, relics, or very large targets, set the Ground Balance at approximately 2. PulseScan AMPHIBIAN Owner's Guide GROUND BALANCE - KNOB What it does This control adjusts or balances the interference from ground mineralization. It is only operative when the Ground Balance toggle switch is in the On position. How to use it To ground balance Pulsescan AMPHIBIAN, the search coil is pumped slowly up and down from one inch near the ground to 6 or 8 inches above the ground while listening for a change in sound. # - GET FAMILIAR WITH A TARGET SOUND Put a target on the ground to become familiar with the response of the detector. Please note that the Pulsescan AMPHIBIAN is a motion detector which means that as the search coil passes over the target you hear a response only when the search coil is kept in motion. Stopping over the target, the signal will disappear and you only hear the threshold hum. Be sure to use a reasonably sized target, so that you can get a better idea of what a target sounds like. Note that the target audio will get louder, and the pitch will rise as the search coil passes over the target. Now is a good time to adjust the volume on the headphones so that you can hear a good response from the target while being able to hear the continuous hum of the threshold when no target is present. Sweep the search coil from sideto-side overlapping each pass. Keep the search coil flat to the ground as you are sweeping from side-to-side. PulseScan AMPHIBIAN Owner's Guide 7 #4 - DETERMINE IF GROUND BALANCE IS NECESSARY (With Gnd. Toggle OFF as on Chart A. ) At this point it is important to find out if there is enough mineralization in the ground to require the Ground Balance control to be activated. toggle is set to off there is no active ground balance, and the Pulsescan AMPHIBIAN has only its inherent ground rejection ability working for it. When the search coil is swept over the ground and there is no ground noise, (the detector runs quietly and smoothly) then there is probably not enough ground to balance. a) You may leave the Gnd Bal toggle in the Off position and operate the Pulsescan AMPHIBIAN with no Variable Audio as a straight pulse detector, and dig all targets, or . . . b) If you wish to detect with Variable Audio active, you may switch the Gnd Bal toggle to the On position and activate this capability, and set ground balance according to Chart on page 22.
