Teknetics ROADRUNNER Operations Manual
Assembly of this unit is easy and requires no special tools. The only assembly required is to attach the search coil and lower stem to the upper stem and the control housing. Fresh batteries can then be installed and the detector will be ready for use.
1) Depress the adjustment button on the lower stem. 2) Push the lower stem into the upper stem. 3) Wind the search coil cable around the stem as shown by rotating the lower stem within the upper stem. CAUTION Provide enough slack in the cable near the search coil end to allow for proper adjustment of the search coil angle. 4) Position the lower stem adjustment button into one of the upper stem adjustment holes. The stem length can be adjusted to fit the person using the detector.
The Roadrunner uses two 9 volt transistor batteries. Access to the batteries is gained by pulling off the snap-on cover located at the rear of the detector. See Diagram.
Attach batteries to battery snaps and velcro battery holders.
NOTE: Approximately 90% of metal detector problems are caused by weak, dead or improperly connected batteries. If the unit does not come on, or comes on and has weak volume, will not tune properly, or has erratic operation or drifts, CHECK THE BATTERY!
It is always a good idea to remove the battery prior to prolonged storage, as weak batteries can vent and leak. This leakage is corrosive and can do serious damage to the unit.
The Roadrunner brings true treasure hunting enjoy ment to that son, daughter, wife or husband for a fraction of the cost you'd expect to pay, and you will be amazed with its fine performance.
The Roadrunner has been designed for ultra sim plicity with easy-to-use automatic features and a single on/off sensitivity control.*
The roadrunner is a state-of-the-art "motion" de tector and does not have a "non-motion" mode of operation. This means that the search coil must be moving slightly to detect and "beep" the pre sence of a metallic object. The ultra slow motion is so slight that pinpointing is very easy.
The automatic ground rejection circuitry allows operation in virtually any mineralization and at the same time buried iron and foil trash is automatically ignored.
The unique dual tone "beep" and automatic iron rejection makes finding treasure easy and fun.
Stand with your arm extended only slightly in front of your body. Don't bend or stoop, but stand in an upright position that is comfortable. Hold the unit so the search coil is about 1/2" above the ground. Adjust the search coil so that it is parallel to the ground.
Turn on. 1) With the coil approximately 1/2" above the ground.
2) Turn the "on-off/Sensitivity" control to ON. NOTE: The detector is normally silent oper ating until the coil passes over a metallic object.
3) When first turned ON, sensitivity will be at its lower setting. Turning the control toward "max" further increases sensitivity.
With the detector in the search position swing the search coil gently side to side, slightly over lapping each sweep as you move forward. Make sure you keep your search at approximately 1/2" above the ground as you search. Raising it in the sweep or at the ends of your sweep will cause false readings. Move slowly, hurrying will only cause you to miss targets.
Most good objects will respond with a good repeat able signal tone. Rejected iron and foil objects generally do not respond. False signals can be caused by black sand, trashy ground, electrical interference, or by large irregular trash objects. These signals are easily recognized by their often broken or unrepeatable nature.
DUAL TONE ATI
The Roadrunner is equipped with a convenient simple Audio Target Identification (ATI) system that auto matically classifies detected metal objects into two categories.
Accurate pin pointing takes practice and is best accomplished by "X-ing" the suspected target area.
1) Once a buried target is indicated by a good tone response, continue sweeping the coil Over the target in a narrowing side to side pattern.
2) Take visual note of the place on the ground where the "beep" happens as the coil is slowly moved side to side.
3) Stop the coil directly over this spot on the ground.
4) Now move the coil straight forward and straight back towards you a couple of times.
5) Again make visual note of the spot on the ground at which the "beep" occurs.
6) If needed "X" the target at different angles to "zero in" on the exact spot on the ground at which the "beep" happens.
REMEMBER: The detector will beep just as the center of the search coil passes directly over the buried target.
If you have difficulty pin pointing very strong signals, try lifting the coil higher off the ground until a weaker but more concise signal is heard. For very weak signals try moving the coil in short quick sweeps closer to the ground.
Treasure Hunter's Code of Ethics:
1 Respect the rights and property of others.
Observe all laws, whether national, state or local. Aid law enforcement officials when ever possible.
3. Never destroy priceless historical or archaeological treasures.
4. Leave the land and vegetation as it was. Fill in all holes.
5. Remove all trash and litter when you leave.
6. All treasure hunters may be judged by the example you set. Always obtain permission before searching any site. Se extremely careful with your probing, picking up and discarding of trash, and ALWAYS COVER YOUR HOLES!
