PINPOINTING

The sweep speed of the detector is slow enough to allow pinpointing in the Motion Discriminate Mode
but will require a little more practice. Move the coil slowly from side to side and then from front to back
over the target. Raising the coil slightly and slowing the sweep speed will narrow down the detection
area enough that it's easy to tell where the coil center is at the instant of sound.

Another easy method is to sweep the coil from side to side across the target in very short sweeps as you
slowly move forward and backward across the target. Slow down the sweep rate and shorten the sweeps
until you just barely get a response at one spot. The target will be directly below the coil center at this
response time.

The easiest way to pinpoint for most people will be to switch to the ALL METAL Mode, since
no-motion is required. To pinpoint a target that doesn't saturate the audio, just move the coil forward and
back and side to side until you get the strongest sound. The target will be directly below the coil center. If
the audio saturates over a large area, simply hold the coil over the target momentarily to detune the
detector. This will narrow its field of response to allow you to once again seek the area of strongest
response.

Detector Protection Checklist

Congratulations, you have just purchased a new metal detector, and we wish to thank you for choosing
Tesoro.

So many people are disappointed when their new "state-of-the-art" detector becomes less and less
exciting to use and doesn't seem to go as deep anymore. There is something that you can do to keep your
new detector working as good as when it was new.

The most important thing is simply to remember that your detector is an electronic instrument and to treat
it as such. You wouldn't expect your TV set to operate properly if you stored it in the trunk of your car,
would you?

We have generated the following list to help you take care of your detector and to help ensure that you do
not void its warranty. If you will follow its guidelines, you will find your detector will not let you down.

Operate your detector exactly as recommended in the instruction manual.

1.

Do not attempt to modify or repair the detector's electronics.

2.

Cable is hard-wired into searchcoil. Do not attempt removal of the spring retainer on the
searchcoil housing.

3.

Use only high quality carbon-zinc, alkaline, or nicad batteries. Remove batteries during long term
storage. Never substitute batteries of other voltages. Brands should not be mixed. Do not attempt
to modify the power supply system.

4.

Never spray lubricants such as WD-40 or any types of cleaners, sealants or other chemical
preparation on or into the detector.

5.

Avoid banging the searchcoil against rocks or foundation walls.

6.

Always protect the searchcoil with a properly designed scuff cover.

7.

Remove and clean out scuff covers periodically to avoid buildup of mineralized or metallic
particles.

8.

After use, clean the detector with a soft cloth to remove any dust, moisture, or other contaminants.

9.

Do not transport or store your detector in the trunk of your car.

10.

Keep cables properly wound to stem and protected. Floppy or pinched cables may short causing
erratic noises or unnecessary replacement of searchcoils.

11.

Protect the detector from dust, moisture, and extreme temperatures during storage. Avoid storing
it in places such as attics, basements or garages. When shipping the detector, use the original
factory carton or a similar heavy-duty container. A one-inch minimum clearance of padding
around the detector must be provided when shipping.

12.

Treat your detector as you would any sensitive electronic instrument. Although ruggedly
constructed and designed to withstand the demands of normal treasure hunting applications, it is
