RNB PWR-PLEX 3000 or 6000 External Battery Pack for Nokta Makro Simplex+

More Battery Power. Longer Hunts. Less Downtime!

There's nothing more frustrating than getting into a productive detecting area and seeing your metal detector's battery running low.

The RNB Innovations PWR-PLEX External Battery Pack gives owners of the original Nokta Makro Simplex+ an additional rechargeable power source for extended metal detecting adventures.

Available in two capacities—the PWR-PLEX 3000 and PWR-PLEX 6000—these battery packs are designed to keep you detecting longer without relying solely on the detector's internal rechargeable battery.

Whether you're searching an old homestead, exploring acres of farmland, hunting coins in a park, or spending the weekend at a metal detecting event, the PWR-PLEX is a practical addition to your equipment.

Ideal for:

Keep Hunting When the Targets Are Good!

Imagine spending hours researching an old farmhouse, forgotten picnic grove, or historic settlement.

You finally get permission to detect the property, and the signals start getting interesting.

With an RNB PWR-PLEX battery pack, you have an additional power source ready for longer sessions.

For serious relic hunters and coin shooters, extended battery power can be especially valuable when access to a promising location is limited.
