The Cortes I had was a very accurate detector. If I remember right, nickels we’re almost always 21, dimes 80-81 quarters and up fell into the 95+ range but on the 9 segment bar graph of the Cortes I could tell roughly what was what. The bar graph on the machine I had was also very actuate.
I remember when pinpointing if quickly passing the coil back and forth over the target it would lock on pretty good and give very stable ID’s even when the target was detection fringe deep.
If you get a stable, locking #18-29 the potential for a ladies ring is very good! Trash targets like to bounce all over but round.. like most detectors likes to lock on quite well. On this machine the locking effect vs. Bouncing # is very pronounced compared to other machines I’ve used.
I picked up a cz6 once. This thing could air-test a dime at 11.5- 12”! I was like wow! This is the deepest machine I’ve ever owned.
I took both machines out to and old one room school site that I had absolutely pounded with the Cortes( same circuitry as Deleon, just a couple more id features and toggle switches). I worked it hard, dug some deep iffy targets, most of which turned out to be bottlecaps, foil and such. I’d recheck them with the Cortes to see if it could hit them, it did. After finding one that rang up high into silver and gave and eaqual amount of iron grunts on the cz, I took the Cortes over. It sounded off Similarly.. The cz was giving a bunch of iron grunts mixed in with the high tone but I could lift the coil about 3” before completely loosing the signal. On the Cortes while scrubbing the coil on the ground I could start to get a fairly stable 80 out of it but I’d loose the signal if I lifted the coil about 1- 2”. It was a very iffy target. I slowly dug the target to find a silver dime sitting almost perfectly on edge at 6.5” deep.
It was a good lesson for me to see just how differently a detector responds to targets on edge vs. Laying flat.
