🙋 WANTED WTB: Broken or busted pinpointers

[mh9162013]

I need to replace my current pinpointer (I think it's a Bounty Hunter), but I don't want to use a 9V battery with my new pinpointer. I will probably buy a Minelab Pro-Find, Fisher F-Pulse, Whites TRX or the Garrett Pro-Pointer AT (aka: the Garrett Carrot). But if I buy one that uses a 9V battery, it's staying in the package until I have a functional method or operating it without a 9V battery. Because using the Minelab or Garrett Carrot is my preference, I will plan on examining the feasibility of running either with AAA batteries (lithium, NiMH LSD and alkaline).

Therefore, I need a pinpointer to work on when trying to size everything, but I don't want to work on a fully functional one, in case I break it during development. So I'm looking for anyone who might have any of the following pinpointers:

Minelabs Pro-Find 35
Any version of the Garrett Pro-Pointers (AT, Pro-Pointer original or Pro-Pointer II).

I'm willing to pay $5 per propointer + your actual cost of shipping. I can pay via Paypal and will add $1 to cover the fee. If you feel a higher price is warranted, let me know why and I may be willing to give you more. For example, if you have a Garrett Pro-Pointer and the only thing wrong with it is a broken switch, I'd be willing to pay more than $5 for it.

Oh, and I'm only looking for sellers in the USA (to save on shipping costs on my end, that's all).

Thanks for looking!

Mh, welcome to treasurenet, great to have you.

There always has to be a charter member involved in any sell either as seller or buyer, since your not a charter member it means only cm can reply with offer to sell, anyone else who replies with offer to sell who isnt charter member their reply will be deleted. Just giving y po u heads up incase you see post disappear you will know why.

 

[mh9162013]

Ok, thanks for the heads up.

How do you become a charter member?

 

[mh9162013]

Update: Now only looking for Pro-Find 15 or 35 pinpointers. Now willing to pay $10 and up (plus shipping), depending on unit's condition.

 

[mh9162013]

Also willing to purchase fully functional Pro-Find 35 (and maybe the Pro-Find 15) units.

I'm curious as to your aversion to a 9v battery? If it's a rechargeable 9v battery you wish for then get one with a 9.6v rating like i have. It's the lower voltages of other 9v rechargeables that presents the problem with them as they still have plenty of power left in them, but their operating voltages go below the minimum voltage requirements of the pinpointers.
Here is a link to one and get a good charger for it too if you go this route.

What's my aversion to the 9V battery? What's your aversion to to horse drawn carriages as a primary means of personal transportation?

If you're truly curious, you can read my other thread about it heredeleted by mod for rule violation, no links to other treasure websites)

OK, I read the first page and you have a point in that a 9v battery will only supply so much power due to its size. Other types are more popular and add physical size to achieve the higher electrical capacity. The 9v battery was a compromise battery to the needs of the electronics vs size of the battery way back then. AA batteries were unpopular then just as the 9v battery is unpopular today. Your best recourse is an external battery pack that wires into the pinpointers or whatever else you wish to power, but involves the wired leads and a passage way into the device which could compromise it with a water or rain event. If you come up with something innovative please do write it here so that we may see what you've come up with.

Adding that any modification to a device could compromise the warranty on it.

I will definitely post a thread when I'm done; I already have a working prototype. I'm now stalled because the next step is to cut up the pinpointer itself and I REALLY won't want to do it when I haven't even taken it out on a hunt yet and it has almost 100% of its warranty left.

That will work, but being the voltage converter is being run by the battery and the on/off switch is further up the circuit, this will continue to draw power from the battery until dead if you don't disconnect it. Furthermore, if it is equal to a 9v battery then why go through all of this trouble as you can get a rechargeable 9v battery instead and the on/off switch will disconnect the battery from any draw?

Yeah, there will be parasitic current draw and yes, this is a lot of trouble. So why do it? Because I HATE 9V BATTERIES THAT MUCH. It's also a symbolic way I can try to stick it to the companies that are too stubborn or cheap to innovate.

There's some people on the forum good with 3D printers.
You might what to look into having a case 3D printed.

But 3d printing is the easy way! But yes, it would save me from having to cut up my current end cap.
