You should not carry watches, belt buckles or metal plates in your shoes, as 
they could cause false signals if close to the search coil. 
Walk normally, and if the terrain allows it, carry the search coil at a lowest 
possible and constant level operational height over the ground. 

The small shallow metal objects will produce two peaks of the ticking-
rate/meter deflection . Lifting the search coil could cut out such small 
sized objects. There are some trashy areas, where bringing the coil higher would 
be advantageous. A mid-sized metal object buried at one meter or so, will give a 
very clear, distinguishable indication. A Large metal target deep in the 
ground will cause a long indication over a larger area than the smaller metal 
objects. 

With some practice you may be able to estimate the depth (shallow targets 
only), the size and even the form of the target detected. The best way of getting 
acquainted with your detector and its responses to different metal targets is to 
locate your buried metal pipes around your home. Of course, the reaction of the 
detector would be much better if the metal targets have been buried in the 
ground for a longer period of time (like 30 to 50 yrs). Walk the test area making 
sure that you are passing all the way through the target until the unit is quiet 
again. Make necessary adjustments to your detector, and tune it carefully away 
from the targets. Try to carry the coil 2-6” high, if the terrain allows that. Pass 
over your buried utilities. Note the differences between the indications of the 
targets. 

Being in Automatic Mode, stop over one of your targets. In few seconds the 
detector will tune itself to this metal object. You’ll then be aware of that through 
the ticking rate, which has already become normal, as set by the manufacturer 
for the Automatic Mode. Move aside. Pass over the same target, this time not 
stopping your movement over it, and the detector will register it again. So, don’t 
stop the search coil’s movement over a metal target while operating your 
detector in Automatic Mode. 

While testing the detector, please note the following: 
-Try to keep a constant operational height of the search coil. 
-The detector is very stable while in its Automatic Mode of operation. 
MegapulseIII successfully compensates the effects of the changes of the search 
coil’s operational height, and retunes automatically to the changes in the ground 
conditions and to the slowly changing external electromagnetic fields. 
-MegapulseIII is a typical motion detector. This means that the search coil 
should be moved over and through the metal target, if you stop your 
movement, then the detector will automatically retune itself and you’ll loose 
the target.
