joehunters news accu pack




new year new resolutions for my joehunters visual ground scanner
hello my friends long time no see sorry for the late news because i have already finised my accu pack batteris it take long time to me to build it . i must be careful to the accu pack batteries .i don't want to make mistake again and don't want to damge high tech device .bro i consider to build the ultrafire back for what did you says.i am
not give up person but i try my best for this device because joehunters is the best and simple high tech device for me. bro i just buy my (lipro balance charger )it is a cheap device are you think it ok ? thank for you advise for fun finder joehunters visual ground scanner . see picture

regards

happy new year

hello member geotech fourm happy new year .ferinds may get new inspiration and ambition for all

[syed ayub basha]

hello GEO-I please tell me your useing it. what depth you will get with it. is it any problems with the geohunter? you said your jeohunter is 4 years old. present day model is the same or any thing chang. please guid me all the jeohunter users. please

[geo-i]

good device

hello syed joehunter is a good electronic device because i have been using for about 4 year now but my joehunter had a batteris problem and i miss my joehunter very much.

invinting

hello my friend thank for invinting me to your country but in my country they do not now how to use it .because that i am tried to learn and aspire to open my shop and teach anyone like you how to use it who intersted in this good device.thank

SIR, I AM GOING TO BUY JEOHUNTER, IT IS RIGHT CHOICE OR NOT PLEASE TELL ME.

Good Luck everyone finding treasures in 2012!

Hi geo-i, my friend,

in which country you are living? maybe you can visit Turkey and
Makro Group or you get such a 1m coil used for the half money.

For you first 1 or 2 good working accu-packs have priority and you
know that you can detect over 3m deep with your standard coil!

For the 1m coil better have second person and a mini-excavator!

good coil

hello friends how are you sorry there is no news because i have not finished making my batteris yet .i am slow learn bro. sorry i dont have the search coil like you have nice coil you have but i can not afford to buy .

1m coil test

Jeohunter 60x100cm coil -
everything @ iron on & ground balance 0:

aluminium-toolbox 45x35cm; 90% sens. ca. 1m75
100% sens. ca. 2m10

sheetmetal-dustpan 20x20cm:
100% sens. ca. 1m35
90% sens. ca. 1m10

silver dollar 3.8cm @ 100%: ca 35cm-40cm
in front of the coils edge (see below) 30 cm

canned tuna 8.5cm: 100% ca. 75cm
90% sens. ca. 65cm
in front of the coils edge (see below) 50 cm


Conclusions:
Bette depth improvements compared with the 35x45cm standard coil starts @ 15cm diameter and above sized objects.

3.8cm one fine ounce silver dollar detectable at nearly 40cm!
This means you even will find usual coins with this 1m coin @ around 10-15cm depth!


Super depth results which will be better as with the standard coil for objects with 30cm in size and deeper than 2meters!

For everything else the standard coil is the first choice.



Not comparable with PI. The PI must use very few windings for short pulses (building up and break down of EM-field plus signal analysing time), otherwise very slow recovery speed and very few windings means very low inductivity that can cause alot trouble, picks up radio interference and gets problems with hotrocks and discrimination.

However this coil has 2 belts at the smaller ends so 2 persons are needed, if there is no slide or little scooter with plastic-wheels.

Perhaps I will mount that coil on a very old full-plastic snowboard for making some real tests in 2012 outside at some snowy fields.

thanks

hello my friend thank for all you help i try my best bro .

btw you also could use Radio control
battery packs instead of single cells!

google for:
rc 4000mA pack 14.8
or
rc 5000mA pack 14.8
rc 10000mA pack 14.8

Hi geo-i

cool that you can use the new accu-drill info.

You will find a way to power the Jeohunter, some possibilities are:

- order original loader and 1 or 2 accu-packs from makro group
- get a usual lithium loader that supports your UltraFire cells
- use the still good working accu-pack of a (old) laptop!
- get some tools like battery-drill that uses big energy packs


It depends how much time you want to search:

The original Jeohunter accu-pack has 4000mAh (@ 14,8v)
and you can search 6h (you can get more time if you switch
off the detector while digging) or even 9h if you search
with the switch LCD screen light off mod (see below) -
simple adding a switch to the most right black cable.

It's better you have a reserve-pack, too.

If the battery-drill info says it has 2000mA it may have just
1800mA for real which would be just around 3-4h searchtime.

So perhaps the really best solution for you is to buy
a li-ion-charger which can load the already given combination
of 2 times 4 cells directly:

__-- -[- 3.7liion +]-[- 3.7liion +]-[- 3.7liion +]-[- 3.7liion +]-+__
....-- -[- 3.7liion +]-[- 3.7liion +]-[- 3.7liion +]-[- 3.7liion +]-+


You will have much longer search time if you buy a second
set of 8 UltraFires 3000mA and a matching loader !!!

Such a pack would have in total 6000mA @ 14.8v and
a search time of 9h or even 13,5h with the LCD mod!

And if you have 2 such power packs you can search for
2 whole days without any charging!

There is not much difference in price if you buy a
battery-drill with really powerful accu-pack or a liion-charger
with a second set of 3000mA lithium ion or li-polymer cells.

Also keep in mind how you want to attach the battery-pack
to the Jeohunter. 8 UltraFires could fit into the original place.


And don't forget:
Please show us pictures how you have connected the accu stuff.

accu -pack result

hello my friend i was still alive not dead yet bro.
mary christmas and happy new year to all geotech fourm member
my friend i have bad news with my accu-pack it do not work very
well bro i think want to give over the accu-pack and tried your
accu-driil experiment that you give .i hope it can work and pray
for me thank .

Happy Xmas 'n good luck in 2012 everyone!

@ geo-i
How you're doing? Still alive? Accu-pack works?

btw. perhaps there is another interesting option for ya:

Visit the next Do it yourself-market and get a battery drill.
It should use a 4 x 3,7v li-ion pack with at least 2000 mA.

Now - all you have to do is to create a matching connector
so you can use this pack also together with the Jeohunter.

2 months ago I built such a pack for another detector
and the accu-drill is still usable with it. I had some
USB - plugs so I used these. However this special
USB is for power source out 11,1 volts only and
it uses extra contacts for the charging-station.

thank advice

hello my friend thank for your advice and guide
i will be in touch thank
