    Walking Through the Owner's Manual

    Would there be a value for all of us to take the Owner's Manual and go through it? We can proceeds as a "new user" and all contribute and see what we come up with. It is amazing what we miss that other catch and how much there is in what I think is an excellent Owner's Manual. I don't learn...

    IM-15 and IM-16 Illustration

    The illustration may help with seeing how discrimination and null interact.

    Ground and Target Signals (A little Technical)

    This is a little technical and intended to give the idea of how soil mineral are eliminated in a Time Domain detector.

    Why the EX has no problem with soil minerals.

    There is a good reason why the Explorer does not have problems with soil minerals. I have been thinking about how to cut through a lot of pages of technical explanation so here is a shot. The Explorer has a sequence of pulses that are long, short and medium. A specific number of pulses are a...

    COINS PROGRAM

    I have been asked for a Coin program for trashy fair grounds. Here is the one I like to use to hunt old fair grounds. The illustration Fig A is the basic program I use for most hunting. All I do is modify that program. I prefer to hunt with a threshold and take my time and pick through the...

    Tones/Name that tune!

    Consider what happens when we sweep the coil over a silver dime and then a piece of iron. We will hear a nice high tone for the dime and see a digital reading of about 0/30. When we sweep the coil over the iron we hear a low tone and the digital reading is 31/31. None of us have any problem with...

    FD and TD Detectors

    When we read a posts on the internet about metal detector one thing to notice is the use of "phase" such as phase angle and the like. The detector and electronics being discussed is FD, frequency design, and very different than a pulsed time domain machine like the Explorer. In a way it is like...

    Ghost Signals, OH Heck!

    I often see a post where a signal is detected, can be pinpointed, but no target found. If something is actually detected, not just ground noise or stray RF, a hot rock will cause this problem. The detector looks at least two major events to determine if the target volume consists of soil only or...

    How a COIN looks to the Electronics. TECHNICAL

    A use coin can be analyzed and represented as a simple L/R circuit. L is the inductance and R the resistance. They are considered to be in series with a sequence of long and short pulses as the source which is the TX of the detector. The long and short pulses have both high and low frequency...

    Deep Coins and IRON Settings

    Here are settings that will work nice for some users when searching for deep coin and jewelry mixed in with iron. There are times when I like to use all metal detecting. I will work an area and clear the trash. I dig the strong target up and remove them so have some pretty clean ground other...

    Technical Explanation of Semi-auto and Manual Sensitivity

    We read some interesting post about semi-auto and manual sensitivity so let me explain what they are for. I know we all understand or at least believe the higher we have the sensitivity set the better off we are. That is not exactly true so hear me out on this one. The transmitter and receiver...

    Forum topics

    The forum can be used for very advanced topics and basic ones. I have never seen any reason to restrict a classroom forum to one or the other. We can follow the there of interest just as we can watch Fox, CNN or both. If we want to "just keep it simple" then we follow those threads. If we want...

    Chris, Here is a quick general idea that is very boring.

    Chris, the idea of inducing eddy current into a dime that is 12 inches from the coil and then the dime induces current into the receiver is takes a giant leap of faith to say the least. I think there is a much better way to consider what actually takes place. Here is something I threw together...

    Detecting in IRON

    We can detect good targets mixed in with iron. If we set our detector to IM-16 and sweep the coil over targets, both good and bad, we see that all the targets are detected. If we are detecting in iron and have a constant null or sound then we need to make adjustments which can be settings or...
