About Arca

We built Arca because TENS devices were overdue a rethink.

Many TENS units treat one area at a time. When discomfort affects more than one place, that can mean moving pads between sessions, resetting controls and dealing with trailing wires.

Arca is a wireless dual-zone TENS device designed to support two areas at the same time — two independent channels in one compact, app-free kit.


The technology

TENS — transcutaneous electrical nerve stimulation — sends low-level electrical impulses through pads placed on the skin. It is used by some people as part of a pain-management routine. Proposed mechanisms include modifying pain signals and supporting the body’s natural pain-relief processes.

TENS does not work for everyone and Arca is not a cure or a diagnostic tool. Read the supplied instructions and safety information before use, and seek professional advice if you are unsure whether TENS is suitable for you.

  • Wireless dual-zone operation
  • Two adhesive electrode pads included with the device
  • Six treatment modes
  • USB-C rechargeable
  • No app required

Who it is for

Arca is designed for adults looking for a compact, drug-free option to use as part of an everyday pain-management routine for areas such as the neck, back and muscles.

You have 30 days from delivery to request a return. The device may be returned after use in its original packaging with all included items. For hygiene reasons, only unopened pads are refundable; £9 is deducted for each opened two-pad set. Customers normally pay return postage unless a fault is confirmed.


UK-based support and dispatch
