Earlier this week someone asked about the <STRONG><STRONG>Cibola</STRONG></STRONG> and I made some comments to him concerning how it operated in iron etc. Yesterday, I was fortunate enough to get with the machine for a few more hours in a second camp with much iron. I also brought a top of the line machine that has multifrequencies as well as both a smaller coil for working around iron as well as a 15" coil for digging deep targets. This camp is nestled on the side of a hill with about 40 to 50 hut sites both seen and unseen. It has been pounded recently due to construction in and around the camp. Do to the amount of iron both shallow and deep, the <STRONG><STRONG>Cibola</STRONG></STRONG> was a bit of a bear to operate as the there is much iron everywhere. If you turn your disc up to above iron you will lose most buttons so you have to keep the disc down as well as the sensitivity down. What is down? The disc set to minimum and the sensitivity set to 8-10. Even with those settings the machine would pop on square nails every few feet making target determination difficult. Even by turning the disc up-there were mutiple target responses that when dug would turn out to be bent square nails. Again using this machine I was able to pull a few buck balls out of the ground. These buck balls have the same sound as a cuff button so the more you dig, the better chances you have of finding a cuff button.
I detected for a period of about 7 hours (1 hr using the <STRONG>Cibola</STRONG>) and located a few buck balls and one small cartridge box rivet. I finally gave up using the <STRONG>Cibola</STRONG> as it was <span style="background-color:#ffff00;">too difficult to operate in this area </span>and switched over to the multifreqency machine.
With the multi-frequency machine and the small coil, I was able to pull a handful of buck balls out of the ground, a precussion cap in a hut that I dug out. An odd wire thin buckle (suspender buckle).
Summary, using the standard coil in an iron infested area with both shallow and deep signals, it is very difficult to use the <STRONG>Cibola</STRONG> without getting multiple hits in an area or constantly digging iron nails (square).
<span style="background-color:#ffff00;">*Problems- (1) If the area has too much iron you will get to many good hits that will make digging impossible. </span>Solution- turn the disc up and the sensivity down- but by doing this you will lose out on many fines.
Solution- dig anything repeatable even at the disc setting of minimum. By doing this you will work the law of averages and end up finding something someone left behind because they didn't dig, and you did.
<span style="background-color:#ffff00;">*Problem- (2) Even with the disc setting higher just below tab- Mutiple "good" sounding targets sounded off by the machine, and when dug the signals ended up being square nails. </span>Solution- turn disc down to min below iron and again dig the nails, and use them later for a test garden. Using the law of averages you will find something valuable that others left behind.
Solution- purchase a smaller coil and slowly re-work any area like this, being methodical in your search and grid out small areas. You should find something someone left behind because they didn't make the effort to locate the deeper targets and you did!
Although the air test between a button and large square nail at minimum discrimination will notch out the nail, in the field this does not prove to be true especially when nails are everywhere making digging rather difficult. For those individuals who dig cellar holes, it might be a bit of a problem to make the determination to dig or not to dig. From my research apparently the circuitry of the T,V, and C are the same in lines of discrimination and the only difference is the "C" is turn on and go and the "T,V" you can ground balance. In an area which doesn't have too much iron, say iron pieces every 1 to 2 feet, this machine would do well. However if the iron is littered on the ground as in this camp every 2 to 4"-digging is impossible- or tackle the ground by getting a smaller coil apparently the 5.75 coil.
Out of a seven hour period of detecting, I used the <STRONG>Cibola</STRONG> about 45 minutes to 1 hour as compared with the multifrequency machine that was used for up to 6 hours. Whenever you are in this type of hunting condition, the best area to detect in is the iron. Some of you may ask, "why"? In those areas you will find the best of the relics or coins. Other machines will behave similarly in these conditions. No machine is 100% detectable in iron. Tales of the Nautalus being able to dig through iron are noted, however it would be easy to guess that only some of the relics or coins have been dug do to the incredible amount of iron at any given site. Next strategy is to turn the clock back by turning the disc to minimum using the <STRONG>Cibola</STRONG> and dig every signal as if it were an all metal machine as that is how it reacts in this particular area and dig some good targets that others were to impatient to check out.
<span style="background-color:#ffff00;">Overall impression of the <STRONG>Cibola</STRONG> with the standard coil in this particular camp was fair to poor</span>. I have been detecting for 30 years with most top of the line machines. Primary machine is the Minelab Explorer XS, and back up is the <STRONG>Cibola</STRONG>.
<span style="background-color:#ffff00;">Any thoughts or comments would be appreciated, especially if there are some seasoned, experienced users using either the "T, V, or <STRONG>Cibola</STRONG>", in similar conditions.
