PRO-ARC Comprehensive Operating Manual & Guide to Metal Detecting

Quick Start

Use your PRO-ARC right out of the case

1. Assemble the detector (see instructions beginning page 10).

2. Install four AA alkaline batteries. All positive (button-end) 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 PRO-ARC starts out in the Discrimination Mode, with:

Sensitivity preset to 60

Discrimination Level preset to 10

Number of Tones preset to 3

Process# preset to dE

Sweep the searchcoil from side to side, parallel to the ground. Keep the searchcoil

moving over the ground. If you stop moving the searchcoil, 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.

Comprehensive Operating Manual & Guide to Metal Detecting PRO-ARC

Quick Start (continued)

Rotate the Settings knob to the left (counterclockwise),

Reduce the sensitivity setting until the false signals go away.

After 7 seconds, the machine will exit the menu and return to normal operation.

7. Find a patch of ground free of metal, 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 and hold 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.

PRO-ARC Comprehensive Operating Manual & Guide to Metal Detecting

Assembly

1. Remove all components from box.

2. Attach searchcoil to lower rod by lining up the holes.

Push coil knob through hole and tighten knob gently.

You will tighten up the coil knob later.

3. Insert smallest rod into S-rod (S-rod holds detector body).

Turn top locking collar counterclockwise to open up. Push in pin on small rod. Slide

small rod into upper rod. Click pin into hole and tighten locking collar firmly clockwise.

4. Push lower rod into small rod as follows:

Turn locking collar counterclockwise to open up. If plastic insert tab interferes, push it

down, or turn tube upside down. Push in pin to allow rod to slide in. Slide lower rod in.

Click pin into any hole.

5. Remove Velcro strip from lower rod.

6. Wrap cable around stem as follows:

Leave some slack in cable at base of lower rod. Secure cable at base of rod with Velcro

strip. Wrap cable loosely around entire stem up to bent part of upper rod. You will re-wrap

the cable later after sizing the rods to your height.

7. Push cable into connector on back of housing.

Do not twist the cable or plug.
