White’s Spectra V3 (Vision) Field Test part 2

visionIn part 2 of my ongoing review of the technologically advanced White’s Spectra V3, I was originally  going to cover the cool wireless headphones…however, after a trip to the beach for vacation I switched gears and decided to talk a bit about the Spectra V3 as a beach hunter. So here we go…White’s Spectra V3 review #2… Beach Hunting!

Garrett GTI 2500 Review by Eu_citizen

*Detectorstuff loves user submitted reviews!  Who better to give some advice and feedback than real life users who have plenty of hours behind the coil.  Read HERE for information on being a DetectorStuff review submitter!  Thanks Eu_citizen for another great review!

-Mark

Now when you break this thing out of it’s box… It looks impressive! Nice green colour, big display heavy and steadily built coils.

Everything looks good and so, now taking it into the field will tell if it’s good or not.

Minelab Explorer 2 user review by Eu_Citizen

Eu_Citizen submitted this Minelab Explorer 2 review in the DetectorStuff User Reviews section of the forums. Feel free to write reviews of your own or comment on ones that are already here. Thanks for the submission Eu!
 

Ex2Well when you take it out of the box… It looks plain weird, not really impressive at first. After a while I did get used to the looks of it.

You’ll note it’s easy to put together. And will need adjusting to your length, otherwise it’s going to feel real heavy. (i.e. arm cup, lower rod need adjustments)

It’s not to bad when you’ve done that.

Ok when skimming through the manual you’ll note there aren’t many adjustments, just more or less weird names for them.

Just learn them. Oh and it is a bit noes heavy, if to heavy opt for another coil.

In the field:

Park:

Well I start out at the park and play around a bit and soon I noted.. “I need a smaller coil!”

Electrical Interference Essay by First Texas Lead Engineer Dave Johnson

Electrical Interference

Because of the high sensitivity of modern metal detectors coupled with the proliferation of sources of electromagnetic interference, you are likely to encounter electrical interference at times during the use of your metal detector. It is important that you recognize electrical interference when present, and take appropriate measures to deal with it. This will prevent you from giving up on a worthwhile site unnecessarily, or from sending in for a repair a machine which is working properly.

Symptoms of electrical interference

Electrical interference can cause a metal detector to “chatter” spontaneously, to lose sensitivity for no apparent reason, or to cause periodic audio “wobble” or slow waves of spontaneous sound. What you’ll hear will depend on what model of metal detector you’re using, what operating mode you’re using it in, how you have the adjustments set, and what the source of the electrical interference is. The most common manifestation is spontaneous chatter.

All metal detectors are susceptible to electrical interference, but they vary in what kinds of electrical interference affect them. In a given environment some metal detectors may be affected by electrical interference whereas others may not.

Two metal detectors of the same model in the same environment may be affected differently, because of minor differences in operating frequency or because the controls have been adjusted differently.

Common sources of electrical interference

Common sources of electrical interference include: overhead electric power lines, underground power lines, other metal detectors, telephone lines carrying electronic data, computer systems, electric fences, old CRT-based televisions, cell phones, thunderstorms, fluorescent lights, metal vapor lamps, military aircraft with electronic warfare countermeasures turned on, electric motors, VLF military communications systems, and automobile ignition systems. It will sometimes be the case at home, in the showroom, or in an urban environment that there are several different sources of electrical interference present simultaneously.

1 White's DFX Review by Eu_Citizen

One of DetectorStuff’s newest members, Eu-Citizen has hit the ground running with user submitted content! Here’s his review of the DFX…Thanks EU!

dfxSo where shall we begin with this beast?

When you take it out of the box, it doesn’t really look much. But as soon as you turn it on and want to adjust things.. Whoaa!


Lot’s of adjustments, you could ruin a whole weeks worth of detecting if you’d start out right away and try to adjust everything.
