WM12 location on your harness/pack

Afternoon all, just a few questions for those that do not use a booster and rely on the WM12 module on it's own.
Where and how do you carry it.

I have mine on the shoulder strap of my Camelbak [Pic below] so it is right underneath my right ear.
I do notice the signal cutting in and out on occasions.

But taking into account wise words from JP it appears I have it in the worst position imaginable. It is not 'in line of sight' but on it's end, and the
signal must travel thru the plastic holder as well.
How on earth can one mount it "with the speaker facing in" to get the best reception?, and still hear it.

So, Without using a booster, is there a stand alone speaker, rather than headphones, that can be utilized?, and does/would that work ok?

JP's quotes from another thread:

I recommend users place the WM12 in their trouser pocket closest to the screen with the speaker facing in, this gives the best direct line of sight to the POD to prevent packet loss in the audio (drop outs).

The transmitter is in the POD (screen section above the handle), canvas will not worry it, the WiStream signal does not like to travel through the human body so try to avoid getting yourself between the POD and the WM12

G'day Redfin

When not using a booster I just clip the WM12 module to the strap on the armrest of the detector itself, that way it cannot get between your body and the pod. The speaker faces up and you can hear it quite well, except if very windy.

Just up the volume on the 7000 a few clicks and have the threshold at around the factory preset of 27

I mostly use the B&Z booster and so have the WM12 module clipped to my belt towards the RH side, I found this stopped dropouts when down retrieving the target from the loose dirt once out of the hole.

Ta Dave, that's what I did with the 2300, worked quite well.

Anyone else?

2300? or do you mean the 3030?

Cheers dave

on the 2200 atually, on the 2300 was not exactly the same but similar.

Ok Redfin I see what you mean, looks like a very good setup mate.

cheers dave

This was the 2200, was xc as well.

Ok, went a tad off topic then, a few questions.

1. Has anyone used / or is there a speaker that can plug into the WM12, rather than headphones or a booster?

2. It appears you can plug headphones directly into the Zed? [ see diagram below] Why not a speaker?

3. Our machine was assembled and charged when we picked it up [we were eager LOL] so what is
   the following all about, there appears no further reference in the manual.
A appears to be a slot for headphones, so what is B?

Redfin.

A is for plugging earphones directly to detector. But remember to turn module off or you will get sound from earphones and speaker.

B is for securing the heaphone module to the control box it is a seperate item like the battery pack and is removeable but unless there is a need to remove it don't worry about it.

Thanks GB, questions 1 and 2 anyone?

Firstly I should mention that I do not have problems with the WM12 dropping out unless the module is quite a way from the Z.  I normally clip it on the harness just below my left ear, as I am deaf in the right ear, so this is where it is supposed to fail, but hasn't so far in use.  It could be because I am short, so distance from my shoulder to the Z is less.

Question 2, I am sure that a speaker "module", could be plugged directly in, but technically it would need to be the correct impedance and it would need to have an amplifier, else it would be very low volume, just like you would get from an earphone.  So that brings you back to using a booster, as that is the purpose of the booster.

Edit: I swapped the left & right ear words, as my WM12 is opposite side of my body to the Z.

Thanks for your input Pabs, but headphones work and they do not have a built in amplifier?

It is a question of sound power output that the Z speaker module can drive and this is not just the Z, but any earphone socket outlet is designed for specific impedance earphones and when they are used that will give a responding level of sound power out in DBs (decibels). If a speaker of the same impedance was plugged in then that speaker would provide the same level of sound power out as an earphone. So if you put that speaker up to your ear you would get sort of the same sound, except not as a compact unit designed to fit an ear.

If you plug in a speaker that doesn't have the correct impedance (or close to it) then it is possible that you could either damage the Z earphone output driver or the speaker.

Basically an earphone is just a small speaker of a specific impedance designed to be used directly on the ears, so is usually a lower power/volume output.

re the headphone socket at back of 7000, i tested it out with various headphones, works great, but that makes you still attached to the machine. so i use the headphones plugged into the wm on my chest, i have never noticed any problems, though the sound has to travel through your right arm/clothes and possibly part of your body.

i have plugged the hole on the machine with a earplug to keep the dirt out, probably worth doing as you know how dust and dirt eventually get into everything ... kev

Pabs, great info, exactly what I was after, thanks for taking the time.

Kev, what I was getting at is the WM12 has been said to receive signals better if the speaker is facing inwards, the rear of the unit facing the sender, so where I have it [see pic above] it is not receiving the optimum signal strength. So to receive the optimum output, I either need to use headphones, purchase a booster or find another way of mounting the module, which is the question.

Good tip with the earplug.

I carry my WM12 on a litthe pouch on my harness, is in line with the control box so is protected and I have no problems.

Thanks Goldquest, but how can you hear the speaker when it is in the pouch?

Here is my detecting backpack setup.
I run 2x wm12's one on each shoulder in a pouch so they are secure and harder to loose!
I use headphones mostly but will also run twin wm12 in speaker mode when it suits me.





the bag is a custom job and I made a belt to take the weight of the 6L of water and all the gear that I need to carry.

Awesome set up there Goldhound, and obviously very effective with the headphones.
But does not address the problem.
How can I carry the WM12 with the speaker facing my body and still hear it efficiently?

G'day Redfin

I think you maybe thinking there is a problem when there is none, I don't know why your obsessed with the ides that the WM12 speaker needs to face your body? If that was necessary the clip would be on the speaker side of the WM12 and not on the back of it.

So long as the WM12 is in reasonable proximity to the main detector body (pod) all should be good. Clipped on the harness or belt, or clipped on the arm strap of the detector arm rest, this has the speaker facing up towards you and the WM12 can see the detector body (pod) 24/7 no worries.

I dont have any problems with the speaker facing out .
Why do you want to face the speaker in?
Mine works fine even inside the pouch the speaker has ample volume.

Woah men, I am just trying to improve what I have. I have found good gold so far but always looking for a way to do something better.
JP mentioned the optimum receiving position was speaker facing in.
I have mine mounted on my shoulder.
Since watching numerous clips of others they appear to have a better , smoother connection.
I appear to get infrequent interruptions in the signal and I want to better it.
I just wanted to know what other are doing?

If the optimum receiving position is indeed speaker facing in, I am way off the mark.
Pic below of what I am doing atm.

Try reconnecting your module on a different channel.
I once had an interference problem on the CTX and this solved it.

Thanks Dale, we are off on Thursday for 10 days so will give that a try, ta.

I totally agree, we are always looking to do things better, ask questions etc, that's how we improve.

When you say "JP mentioned the optimum receiving position was speaker facing in." I also read this, and he also said he had the WM12 in his trouser pocket with speaker facing in.

Now I could be wrong, but I think he had the B&Z booster plugged into the WM12 while doing this and the sound was from the dual speakers on the shoulder straps of his harness and being supplied from the WM12 that was placed in his pocket.

If this is indeed the case, the speaker facing in had NO sound coming from it, as the sound bypasses the WM12 speaker and goes straight to the external speakers on the harness when using the B&Z booster system in combo with the 7000 and the WM12 module.

cheers dave

G'day Dave, if the optimum receiving position [facing in] is for the booster, one would think it would be the optimum position full stop.
However,
I think I will leave it there and battle on.
If not, I'll get a booster, its only the cost of half a decent lunch after all.

[quote="Redfin"]Thanks Goldquest, but how can you hear the speaker when it is in the pouch?[/quote]

I use A B&Z audio buster and an external speaker, the sound is perfect.

Hi Redfin ,
Just in relation to your diagram I believe the sender is positioned in the ' pod ' compartment under the arm rest ...

Cheers

G'day GH, it is definitely behind the screen.
This is a reply from JP when asked.

The transmitter is in the POD (screen section above the handle), canvas will not worry it, the WiStream signal does not like to travel through the human body so try to avoid getting yourself between the POD and the WM12.

Thanks for that Redfin , for some unknown reason I kept relaying 'Pod' to the main body compartment ..
Cheers for clarifying that assumption I had ...
