The Power Tank is used to provide the necessary power for most of geophysical instruments and metal detectors by OKM. With this external power supply detectorists are able to extend the operating time for treasure hunting.
The Power Tank is not available anymore. As replacement we recommend the more compact Power Pack.
One external power supply is included in the standard scope of delivery of selected detectors. The additional power supply Power Tank can be purchased optionally to extend the operating time of the metal detector.
The following instruments are operated with an external power supply:
With one fully charged power supply, detector users can work about 3 to 4 hours. By using an additional power supply, the user can extend the time of prospecting for another 3 to 4 hours.
This can be useful if searchers work in areas without any electricity in the nature (where most archeological sites and treasure hunting areas are situated) and do not have the possibility to recharge the battery.
An additional fully charged external battery is a must for all professional prospectors who are working a long time and do not want to stop detecting because of an empty battery.
