Experienced pulse induction detectorists know well that those machines have little to no discrimination capability. Its either a target hit on everything metallic or nothing…and they characteristically go “deep” for all targets within range be they bobby pins, bottle caps, coins or gold rings.
I’ve always been a VLF man so I decided to experiment with the Garrett Sea Hunter just to see for myself how well its discrimination modes worked. I chose the Garrett Sea Hunter because it has a well deserved reputation as being both a solid performer and a ruggedly reliable detector.
Test the operational capability and sensitivity at depth in soil and wet salt sand as well as its ability to discriminate and separate good targets from iron on land.
Procedure : All tests conducted, observations and comments reported are from the standpoint of the average user and not a professional design engineer.
After familiarizing myself with the detector by reading the manual in conjunction with the machine itself, tests were designed to evaluate sensitivity at depth in Soil, [...]
This review is a report of my thoughts and observations of the Smart Phone App for the Minelab GO-FIND 60. It is not an “after-market” user manual or even a supplement to one.
The first thing I noticed as I unpacked the Minelab GO-FIND 60 was the absence of written instructions regarding the operation of the detector or the App. Although instructional pdf forms for the App are available, soon realized that I didn’t actually need hard copy instructions—read on.
Downloading and pairing the App with the GO-FIND is as simple an operation as with any smart phone app. The one extra step was [...]
Purpose : Test the operational capability and sensitivity at depth in soil, as well as its ability to discriminate and separate good targets from iron.
Procedure : All tests conducted, observations and comments reported are from the standpoint of the first time average user and not that of a professional design engineer.
The Coiltek 5×10″ coil was mounted on the Minelab CTX-3030 to determine sensitivity, discrimination/separation and stability. Sensitivity was determined by reporting the greatest depth at which targets of various size and metallurgical composition could be reliably detected.
Purpose : I conducted a field test to evaluate the operation, functionality and capability of this detector in a variety of environments and conditions, running all tests from the viewpoint of the new detectorist.
I first read over the user manual and operate the machine in a sterile environment to familiarize myself with the controls and operation. I then research the machine via the Internet and speak to the manufactures’ technical representatives on any specific questions so as to further and [...]
