Resistance measurements are unaffected by any stray interference signals that may be present in the earth during readings, due to the use of narrow band-pass filters centered at 97Hz (the unit’s operating frequency)
Runs on a set of C-cell alkaline batteries...no need to periodically recharge the unit or to plug it into a power source
The 12oz bottle contains 0.75 lb (0.34 kg) of Copper Sulfate crystals and should yield approximately 12 charges of crystals for conventional RE-5 and RE-5C electrodes.
The 40oz bottle contains 2.5 lbs (1.13 kg) of Copper Sulfate crystals and should yield approximately 40 charges of crystals for conventional RE-5 and RE-5C electrodes.
