faulty Xpointer pin-pointer

[keith777]

Hi guys.
i resonantly bought this pointer off a seller who was selling them on Ebay. it was faulty when it arrived. the seller was contacted, a nice chap by the way. was going to have me a replacement one sent out from the factory. the seller got back to me a couple of days later to tell me that.....

(Very sorry name, The DHL told me they will charge very high cost to delivery to you since the address is a far-away position. Sent the new one to you will cost 3 times than the normal. So I have to decide refund you the full payment. You can keep the detector and choose another brand pinpointer.)

it was very nice of the guy to let me keep the pointer but a replacement one would of been better.
the pointer gives off an alarm without hardly any pressure applied to my hand.
i took the pointer out with me on my last resonant detecting day out. i took the pointer with me just to see if it would be any good to use as a backup or not.

i had to turn the sensitivity down to the level 2 setting for it to work without much folsing. but sometimes it beeped nonstop without moving it at all. so i had to switch it off undo the battery cap then turn it back on again. also the pointer kept switching itself off quit often. i had to unscrew the battery cap off then back on again for it to work again. i come to the conclusion that the battery wasn't connecting properly all the time which was cursing it to switch off.

i have had a quick look down inside the pointer and can't see any wires loos or any thing like that.
anyone any idea if this may be an easy fix or not?
i have added a video of the faulty with the pointer with the post......
thanks in advance guys.

Maybe you have a high iron content in your blood and better the doctor can fix it. This is a joke.


Maybe you can show some pictures of the inside so that the technicians here can help you further.

So what happens with metals? Does it get more nervous with metals?

[keith777]

if you move the pointer towards a metal object it still sounds off as it should do, but when you simulate on your hand searching for a target in the ground or actually try to search in soil/hole etc when out in the fields it sound off all the time when rubbing about. hope that makes sense.
i never thought of showing it in the video detecting metal.

i for got to say. the seller did say in a message that..... (Some of the detector's coil inside is to close to the wall of case.) whether this is the case or not i wouldn't know as i am no Tech Whiz.

when you will get out a board press easily on knobs. you can break a knob, that is getting on garrett pro pointer as frequent case.

i am not going to say its crap cheap rubbish etc, because at the end of the day what should a pinpointer cost?, really
they are not complicated, or bristling with technology, they are actually very simple.
but it does appear that some of the first batches of these have problems,which is a shame as problems at the start of production can kill a device stone dead, it was good of them to refund your money, at least you are not out of pocket.
you need to carefully take the pointer apart and take some photo's of it both sides, inside ,and of the coil maybe we can help, it may be a fault with a switch(like kt315 said), the coil or a connection somewhere, which is why proper photos are a must.
but it may be a production fault that can only be fixed by a revision of the device, it may be a lost cause and you need to be prepared for that.

[keith777]

when i looked down inside it looked as though the coil was resined down in to the bottom of the tip.
taking it apart was very easy. putting it back together was the hard part as you kept getting the 2 wires that lead down to the coil trapped pushing the board in, which was stopping the board from going all the way back in.
i will take the board out again tomorrow and take some pics and put up.

like you say it was good of them to refund me my money back and at least i'm not out of pocket...

also dont forget there are a couple of threads here where people are working on pinpoiners, the main drawback of building your own pin pointer is the lack of a proper case to put it in you have one for free.

[keith777]

here is them pics that i promised of the inner's of the xpointer. sorry for putting them up so late.

Is it possible to remove? The coil out
I personally think that the ferrite rod can be broken. Watching what the others say.

[kt315]

reminder me the garrett pro pointer. also I see the micro like stayed in pro. still it is not the garrett. IMO a generator may be similar to pro one.
pro has a problem in generator, frequently discussed in russian forums that I observe...

googled this info... http://golddetecting.4umer.net/t3465...n-switched-off

If you find too difficult to get the coil out, you can try the following.
You do need a Induction meter.
1 - You measure the inductance of the coil.
2 - you press firmly on the ferrite, meanwhile, keep pressing you measure again the inductance
of the coil.
If then the inductance is higher than the first time then almost
certain that the ferrirt is broken.
success.
