Make sure that when you run into an area that is producing a number of deep coins (6

inches or greater), to make a second search at a different direction from the first to

get good coverage.

One of the hardest techniques to explain is what a really deep target sounds like. It is

the most important target to learn but the hardest to describe. To just say a deep

target is weaker in sound than targets on the surface will not produce the really deep

coins all the time. Experience is the best teacher and very deep targets will often

sound like something not worth digging to a beginner.

The descriptions below assume that you are using discrimination, you have the

sensitivity set on your own setting, (not using Auto), and you are using a SunRay

meter with the Sovereign XS.

A good target on or close to the surface normally will always give a good broad

positive response provided there is no trash on top of or right next to the target. The

beginner should know the sound of a good positive response, and dig these when the

meter also locks onto this sound. Now the deeper the target is the weaker the sound

gets. When a coin target is around 5" or so the sound becomes a very short positive

signal. The meter will lock on and you should always dig this target sound.

When you are using your sensitivity in the manual setting, auto off, there are some

very deep targets that will produce a positive short and weak wavering type of

response. A sound where the tone or pitch will oscillate up and down. It doesn't

sound like a good target because of the up and down oscillation. If the questionable

target causes the meter to bounce around mostly in the positive numbers, you may

want to dig it. Sometimes the up and down oscillation can be so wide and fast

between a negative and positive response that it will have a broken sound. There is a

metal object in the ground when you hear this sound but it may not be a good target.

To prevent a lot of trash from being dug on these questionable targets, you might

want to try the following. First only be interested in the very weak, deep sounding

signals. Get the coil over the target and watch the meter. A good target will cause the

meter to bounce around in an area generally of positive numbers and produce a

positive sound each time you pass the coil over the target. A bad target will generally

null out with no sound or a very broken sound will occur. Be aware that on these

types of signals the bad to good target ratio is going to be high. Checking the target

from a different direction can help identify a good target from a bad one. Another

thing to remember is that if the first thing recovered from the hole is a trash item,

make sure that you recheck the hole. We have found pulltabs, foil, and iron trash in

the same hole along with good targets that gave the good response in the first place.
