Tesoro Cortés Metal Detector is a great target identification machine thanks to all the features that it comes loaded with. First off, this metal detector is super easy to assemble once you read the instruction manual. There aren’t any complicated instructions and directions that can confuse you at any point. After you have assembled, notice the battery holder and the control box configuration. The control box is bigger in size with the batteries moved down under the arm bracket. This makes space for the twelve volt system and 2¼” speaker for enhanced functionality.
There is a 2×16-character LCD screen, which has the alphanumeric display on the top row to give an indication of the probable target. The battery level indicator is at the far right side. The nine segment bar graph is at the center of the display, and this indicates possible targets, like iron, nickel, square tab, copper penny, and quarter. The display will clear itself after not getting a signal for six seconds. You will find a ¼” headphone jack at the back, and wearing it is necessary for detecting the faintest of sounds. The machine operates at 10 kHz.
Some notable features of the Tesoro Cortés Metal Detector include:
#1 The operating modes
There are four operating modes in this metal detector, namely, All-Metal, No-Motion; Sum Discrimination; Notch Discrimination (wide and narrow); Silent-Search Discrimination. In the Discrimination Mode, you will get factory-preset ground balance. The All-Metal mode is for manual ground-balance with a adjustable threshold level. There are factory preset widths in the two Notch modes. The Sum Discrimination is for improved target ID by averaging the signal information and utilizing a nine-tone audio identification.
#2 The backlit digital display
It comes with a backlit digital display that can give either high or low brightness depending on whether you want to hunt in no light or dim light conditions. The digital display can identify targets in three possible ways: a bar graph, alpha characters, and numerical. In addition to that, the clear digital display shows the possible target depth (mainly for the coins), and the battery life remaining.
#3 The identification number
The identification number takes up the largest part of the signal and it gets converted to a two digit number. While making the scale for the identification number, the makers decided to keep the highest resolution in the mid-range targets. This is the point where you will be able to recognize nickels, gold rings, and the likes. You will always get iron on the lower end of the scale and precious metals like silver on the higher end. So, you will get the reading of zero for iron and a reading of ninety-five for silver. With Cortés, you have a choice regarding what you want to hunt for. A treasure hunter searching in the same area gets to use the identification number for learning the features of the local pull tabs so that he/she can ignore them, as needed.
