Summary of Contents for Tesoro Cibola

  • Page 1 If any of these items are missing, contact the Tesoro Authorized Dealer where you purchased your detector immediately. Assembling the Cibola is simple and requires no special tools. Just install the battery packs, mount the searchcoil on the lower pole assembly, connect the pole assemblies together, wrap the excess cable around the pole and plug the cable into the control housing.
  • Page 2: Installing The Battery

    INSTALLING THE BATTERY Your Cibola is equipped with an automatic battery test circuit so that you can always be sure you are getting top performance. The battery should be checked after the detector has been on for about 10 minutes and then periodically when used for long durations.
  • Page 3 3. Insert the mounting screw through the holes in the mounting ears and pole tip—entering from the side opposite the cable connection. 4. Install the thumb nut on the mounting screw and tighten by hand. Note: Do not overtighten the thumb nut. It should be snug but not too difficult to loosen up.
  • Page 4: Adjusting The Pole & Searchcoil

    Note: You will want to adjust the pole length and the searchcoil angle to your preference. ADJUSTING THE POLE & SEARCHCOIL The pole length should be adjusted so that the detector does not become uncomfortable or tiring after long periods of use. The detector grip should rest in your hand with your arm relaxed, your elbow straight but not locked, with the pole extending out in front of you at the approximate angle shown in the photo.

    QUICKSTART - SELF-GUIDED TUTORIAL The Quickstart is designed to teach you how to use your new Cibola. It provides a quick and easy means of learning your detector and the concepts behind all of the functions. You will need the following items: 1.
  • Page 6 DISCRIMINATE Mode and you can continue with the Quickstart. The purpose of the threshold tone is to give a reference to judge targets for pinpointing and to super tune the Cibola. (For more information on super tuning, see the “Super Tune Your Cibola” section on page 13.) In the field, some targets may be small enough or deep enough that they will not be able to generate an audio signal by themselves.
  • Page 7 The SENSITIVITY knob is numbered from MIN to 10 and then has an orange area called the Max Boost zone. For normal hunting, anywhere in the numbered zone will work very well. However, the Max Boost will allow you to increase the power to the operational amplifiers to the point of overload.
  • Page 8 Super Tune Your Cibola The Cibola can be set up to get even better depth and sensitivity while operating in the DISCRIMINATE Mode. Super tuning is accomplished by working in the DISCRIMINATE Mode and turning the THRESHOLD knob to the highest setting.
  • Page 9: Operating Techniques - Field Use

    Super tuning your Cibola will cause the threshold audio level to be set too high for accurate All Metal or Pinpointing operation. To start, turn the DISCRIMINATE LEVEL knob to just above the IRON setting and turn the SENSITIVITY knob as high as it will go without causing the detector to chatter. Check a target or two and notice how far away you can get from the coil and still receive a repeatable audio signal.
  • Page 10 A good method for pinpointing in ALL METAL Mode is “X-ing” the target with the searchcoil. Remember that the target's response sound is always greatest when the target is directly under the center of the searchcoil. To “X” a target, sweep the searchcoil over the target from side to side and then from front to back until you can identify the center of the X—the spot on the ground where the target response sound is the greatest.

    DISCRIMINATE LEVEL is set to reject pulltabs on any metal detector that is a TR Discriminator like the Cibola. If you don’t dig any junk at all, you are surely passing up a lot of good finds as well. Set the DISCRIMINATE LEVEL only high enough to suit the conditions where you are searching.
