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. If there is any doubt whether a target is good or not, 

dig it.

  

Recovering a Target 

If the target is shallow and the soil is soft, you may be able to “probe” and find the exact location 
of the target before you dig it. Since filling all holes after you recover the target is so important, 
digging a small precise hole is best. If the target is deep, you may need to dig a larger hole. As 
you dig, occasionally check the hole with your detector to see if you have moved the object, can 
probe it, or have already dug it. Be sure to fill all holes after you recover the target. Two methods 
are shown on the next two pages that work most everywhere. Be sure to protect your hobby by 
leaving the site cleaner than you found it and with all holes filled!  

 

 

 

 

GENERAL INFORMATION - CARE AND USE 

Basic Care 

The Cibola is a sturdy instrument, but it is not designed to withstand abuse. In caring for your 
Cibola, there are several important “DO NOTs” to remember. DO NOT use it to pry rocks loose 
or to beat bushes out of the way. DO NOT drop the machine into water. DO NOT use it 
unprotected in the rain. DO NOT leave it exposed at night where dew could form on it. DO NOT 
store it in places that could get extremely hot (next to a woodstove or in an attic). DO NOT leave 
it in the trunk of a car or in the back of a hatchback-style car where high temperatures could 
build up. DO NOT store it with the battery installed as batteries may leak. DO NOT spray 
lubricants such as WD-40, or any types of cleaners, solvents, sealants or other chemicals into or 
onto the electronic parts, witches, or controls. And finally, DO NOT attempt to modify or repair 
the detector’s electronics as this will void your detector's warranty.  

THE WARRANTY DOES NOT COVER DAMAGE RESULTING FROM AN 
ACCIDENT, NEGLECT OR ABUSE.

  

Protecting Your Investment 

Often detectorists are disappointed when their new detector slowly becomes less and less 
responsive and seems to have lost some of its original peak performance. You can help avoid this 
from happening to your detector by following these basic care and protection guidelines:  

 

Operate your detector exactly as recommended in this Operator Instruction Manual.
