Comprehensive Operating Manual & Guide to Metal Detecting
QUICK START
Start using your T
2
right out of the box
1. Assemble the detector (see instructions beginning page 5-6).
2 Install four AA
alkaline batteries. All positive terminals point up.
3. Turn the knob, located under the armrest, fully clockwise.
This turns the machine on and sets audio volume to maximum.
4. When first turned on, the
T
2
starts out in the Discrimination Mode, with:
Sensitivity preset to 60
Discrimination Level preset to 10
Number of Tones preset to method-1
Sweep the searchcoil from side to side, parallel to the ground. Keep the searchcoil
moving over the ground. If you stop moving the search coil, the sound will also stop.
Probable target type will be indicated at the top of the LCD screen.
5. If the searchcoil is not in motion and not close to metal, the detector should be silent.
6. If you experience false signals from electrical interference, from the soil itself, or from lots
of trash metal, press the Menu button.
Sensitivity will be highlighted.
Rotate the
Settings knob to the left (counterclockwise),
Reduce the sensitivity setting until the false signals go away.
After 5 seconds, the machine will exit the menu and return to normal operation.
7. Toss a coin on the ground and sweep back and forth over it a few times to get a feel for
how the machine responds.
8. You are now ready to search.
9. Pull the trigger switch with your index finger to pinpoint the exact location of
targets, making them easier to unearth.
When the trigger is pulled, PinPoint is engaged ….
The searchcoil need not be in motion to detect an object.
The 2-digit numeric display indicates approximate target depth, in inches.
Detecting Activities (continued)
Cache Hunting (continued)
stories about the circumstances surrounding the hiding of the cache, you may find discrepancies
which help you to judge the reliability of the information available. Often the best information on
an old cache is to be learned from old timers who live in the area where the cache is thought to
be. In the case of newer caches, often the only information is what can be obtained from family
and acquaintances of the person who is believed to have hidden the cache.
The ownership of a cache is not always clear. Sometimes it belongs to the person or heirs of
the person who hid it, sometimes it belongs to the owner of the property on which it is located,
and sometimes it belongs to the person who finds it — or some combination of the above. If
the contents of the cache were stolen, this fact can also complicate the question of ownership.
Find out what laws apply to the cache in question, and always make sure that the issue of
ownership is resolved prior to recovering a cache.
Compared to a coin, a cache is usually large and deep. Searching in All Metal Mode is
recommended. However, for a really deep cache, it may be advantageous to search in
Pinpoint, frequently releasing the trigger momentarily to maximize sensitivity.
Shallow Water Hunting
All First Texas Products searchcoils are waterproof, allowing you to search in shallow water
about two feet deep. If searching around water, be careful not to get the electronics housing
wet. Avoid salt spray, as it will work its way into the control housing and damage the
electronics — such damage is not covered by the warranty.
Both fresh and salt water beaches are popular places for metal detecting. Vacationers lose money
and jewelry playing in the sand and in the water. It is usually easy to dig in a beach environment,
and metal detecting is permitted on most beaches. Occasionally you may be able to help someone
recover a piece of jewelry they have lost minutes before, this is a gratifying experience.
When searching on a beach, it is best to either search in All Metal Mode, or to search with the
discrimination level set just high enough to eliminate iron, because the value of beach finds is
largely in the jewelry rather than in the coins. You will dig a lot of aluminum trash, but the
digging is easy, and you can tell people that you are helping to clean up the beach and make
it safer for people’s feet. We recommend the use of special
sand scoop for recovering
valuables from the sand quickly — most metal detector dealers sell these.
The electrical conductivity of the water itself can pose some challenges. You may get false
signals when going into and coming out of the water, making it necessary to pay careful
attention to keep the coil either in or out of the water, but not to touch the surface. This effect
may be observed in either fresh or salt water.
Salt water is highly conductive, and produces a strong signal which is like that of metal.
Therefore the
T
2
is not suitable for use in or over salt water. In order to use the T
2
over wet
sand, or salt water beaches, do the following:
1. Set the sensitivity in both modes to 30 or less.
2. Ground cancel the machine manually in All Metal Mode.
3. Search in the Discrimination Mode with a discrimination setting higher than 45, using
the 1+ # OF TONES method.
