    Predicting Targets

    Tone ID and Visual are PREDICT the ID of a target. We cannot squeeze a sound out of a dime and another one from a piece of iron as we all know. A detected target causes a change in the electromagnetic field generated by the detector. We humans have invented all kinds of way to measure that...

    Selecting ICONS Page 61-62

    Selecting target is not that clear when we first start to use the Explorer. There are two ways to look at this I think. If the screen is clear then a target that hits in that clear area is detected. If the screen is black then a target that hits in that area is rejected. The screen is a visual...

    Simplified ID Drawing

    Data is fed to a table that has TCs for different targets strored. They are matched to the data in the receiver circuits and a TC is selected. A circuit then look up the name of the target and outputs visual and audio data.

    Simplified Model of Input of EX

    The illustration is a simplified diagram of the heart of the input of the Explorer. The transmitter and receiver coil are in effect a transformer with a primary and secondary. The soil matrix and any metal in the matrix is the core of the transformer. The shape of the signal in the receiver is...

    Adjusting Audio Tone Page 53-54

    As far as I am concerned this is one of the most important topics in the first half of the User's Manual. I have to understand why there is any need for more than two tones or three at the most. We need one for iron and another for everything else. It makes it fun to have a third one for the...

    Audio Gain

    The gain control is illustrated and explained on page 52 and figure 5.16 and 5.17. It is about a clear a mud to most folks but here is what they are trying to show. Look at my attached illustration. The red line indicates where Audio Gain is set. If set to 10 then we have a very steep red line...

    Screens and Sensitivity Page 47

    I like the Digital Display for a number of reasons. The operator can see the ferrous content and not attempt to do this from the location of crosshairs. However, it really is a user preference as many user prefer to

    Why Mineral are not a problem.

    This may be a litte more technical than some want to bother with but I thought I would go a little deeper into this. There is the idea that the Explorer has problems with soil mineral which is not at all correct so I thought I would go ahead with this and take a chance of being run out of town...

    Intro to Preset Coins Program Page 42

    P32- Introduces discrimination and the preset Coins Program. This program is a COMPOSITE of hundreds of coins from around the world according to Minelab. We need to keep this in mind that is the pattern is FOR NON-FERROUS COINS OR targets that match the conductivity/SIZE and FERROUS CONTENT of...

    Where to set the threshold?

    P48 -The purpose of the threshold is often confused, or at least it seems to me to be, with sensitivity. Consider this and assume I have the headphones on that came with the detector and adjust the threshold to the slightest hum then turn it down to just below sound. We would say I have silent...

    X1, Glenn and Others

    I hope many of you will jump in as I sure don't think I am the answer on the Explorer. I do the best I can to jump the gaps and try to find common ground for a model to help a user translate that to the application of the detector. Many of you have a lot of experience to share and with the X1...

    Pulse Induction Square Wave

    X1 Probe

    All probes I know of other than the X1 type of probe are small metal detectors. They have a power supply, coil, all the circuits necessary to be a simple metal detector. One that I like is the Uniprobe that is a PI detector in a headset. It can be used as a probe or with a shaft and standard...

    Sweeping the Coil (P37) Fig 5.2

    (P37) Figure 5.2 My guess is one major problem with using the detector or any other is failure to keep the coil at just slightly above the ground and swing the coil so it is parallel the ground. A coil has a

    Pinpoint (P32)

    (P32) Pinpoint One of the most valuable aids to pinpointing is measuring the size of a target. The pinpointing mode has an automatic shrinking circuit to help with pinpointing. However, there is no problem measuring the size of a target as the automatic shrinking circuit operates slow enough...
