XP Gold maxx power quick review
Xp metal detectors have been very popular in the UK since the
launch some years back, the XP GoldMaxx took the podium having been specially
to suit the professional metal detectorists needs.
Fast recovery speed and precise discrimination threw the gauntlet down for other
manufacturers to follow.
That's the Mk 1 Gold maxx...what can I say about the Gold Maxx power
There is very little left to be said, so many others have said pretty much everything to say. Some detectorists I have talked to do not get on with the new power, strangely enough most of them were ex Mk1 owners, all new machines take time to learn .
Here is my quick review
I have not been so involved with the latest XP's, there's an old saying
"to many cooks" ...however as you may well know I donated a lot of time and
effort to the original XP launch some years ago, the original Mk1 was a part of
my detecting life and the ONLY machine I used.
The Gold Maxx Power has the same weight and appearance as the original, the
control panel has the only noticeable difference, we now have an "iron threshold" replacing
the original discrimination. This is more of an Iron only rejection
control...just out of auto accepts most iron, then rejecting higher levels
as the control is turned clockwise. For those who don't want to many tones the
GMP can be used like a conventional detector simply by using the Iron
threshold as a discriminator when the Iron volume is turned to zero.
I found the Iron
threshold at the 11 o'clock position with a slight Iron buzz on the Iron volume to be adequate for me.
When the Iron
threshold is turned fully anti-clockwise it clicks into "auto" which is
a fixed pre-set
to reject most hot rocks/coke...wet coke may still give a response.
The frequency shift is linked in with the WS1 cordless headphones, you can read
about them on the XP web site and xp metal detecting forums, I have an original
pair of WS1's, for some reason the battery will not hold a charge so I can
not use them for any amount of time.
The silencer determines how much the iron signal is broken up, this works in the same
way as the original maxx, although 2 or 3 tones are now accessed via this
control. When turned on the machine defaults to the 3 tone setting every time,
to activate 2 tones you will need to quickly switch the silencer from 1 to 2
In the field with the Gold Maxx power
My model came from Detecnicks and fitted with the latest version 4 chip, I
have no idea for what reason(s) this later chip was fitted. The first thing I
noticed was the sensitivity could only be turned half
way before the machine became unstable. Earlier models could be set
much higher, also the sensitivity appears to have a much finer adjustment, the
slightest touch can make the machine very sparky, this allows the
operator to work the machine on the "edge".
The best way I can explain the sensitivity function on the Gold Maxx Power is it amplifies the signal returning from the target and not the power going into the ground (audio boost).
Having settled down with the machine running in 2 tone, iron
threshold 11 o'clock, sensitivity 11 o'clock and iron volume at 10
o'clock it all became familiar again...buzz...buzz....buzz...zing.
The Gold Maxx power performed very well with no noticeable changes to the Mk
At some point I will be comparing the 2 machines side by side in the field.
TIP : When searching in stubble try to bulk wrap the coil lead just above
the first stem lock, this will make the coil slightly heavier and easier to
Comparing the Gold Maxx power to the original GoldMaxx
The Gold Maxx power claims more depth and faster recovery speed, so far I have found no major difference, although if there was an
opportunity to turn the power up past mid way I am sure it will be
deeper on clean pasture.
The only initial difference I can see between the
original Gold Maxx and the Power is the Gold Maxx Power has a
slightly harsher signal on shallow and large targets, almost like a
forced sound, making iron identification a little difficult at
first, where as the earlier models gave a very soft tone on good non
ferrous targets at all depths.
The harsher sound is only noticeable at higher sensitivity settings and may be a trade off for the power running a faster recovery
speed, I have been told the new v4 chip is much sharper than the standard V3 chip which is more like the oiginal Gold Maxx..
The Iron threshold on the control panel is a nice touch and is most
certainly an advantage when searching ancient sites, it save's
taking the box apart and adjusting the 2 tone pot to suit your
sites, as we did when "tweaking" the Mk1.
I would suggest you avoid the "Auto" setting unless you are a total
beginner, this can null the performance and sharpness, however if hot rocks are a real problem you may have
no choice. Here in Buckinghamshire we are very fortunate and have very little
hot rock, I have been sent boxes of samples from around the UK, some just
simply can not be rejected with single frequency machines.
For general searching there are plenty of other machines available
on the market that will do the same job for the same price...However
it's real potential will be apparent when searching contaminated
sites littered with nails then the Gold Maxx or Goldmaxx Power is in a class of
Gold Maxx headphones...Important
As with all Gold Maxx models headphone quality is paramount, get the wrong
match and the singnals will sound dead and lifeless.
I would recommend using the original backphones supplied with the machine,
cordless WS1's or 2's the best heavy duty headphones we have used so far are
the Sprite's, naturally available from me. !!!
Important note regarding metal detector field tests
Metal detector field tests are one persons opinion..on the day...on a particular site, they are not telling you to rush out and buy the machine....please use these independant reviews as a guideline other than a manufacturers report.
