FIT Rife

About FIT Rife

FIT Rife designs and builds the FIT series — a line of frequency delivery devices that has evolved since the first concept in 2012, each generation solving a specific problem in how frequency is delivered: more precisely, more flexibly, more reliably than the model before it.

The FIT Line, at a Glance

• FIT I (2012) — the foundation. Handheld electrodes, voltage-pulse delivery through direct skin contact.
• FIT II (2021) — a different approach. Built specifically for a PEMF coil, delivering frequency through current pulses instead of voltage.
• FIT III (2015) — bringing both together. Combines FIT I and FIT II in one device — electrodes or PEMF coil, one at a time. Upgraded in 2021 with a 4.3" touchscreen; USB-C added July 2026.
• FIT IV (2021) — simultaneous delivery. Runs a PEMF coil and electrodes together, or two sets of electrodes at once. Version 2 (July 2026) integrates the PEMF coil internally and adds USB-C.

All four run on a standard 18650 lithium-ion battery, with durability engineered in throughout — from FIT II's impact-protected recessed screen to the reinforced shared enclosure of FIT III and FIT IV.

The Manufacturer Brand

FIT Rife is the manufacturer behind the FIT series. For over a decade, these same devices were sold through Wave Technologies under separate branding — FIT I as Wave Kompak, FIT II as WavePuls, FIT III as Wave 5 (Professional), and FIT IV as Wave 6 (Practitioner) — without FIT Rife's own name on the product.

That arrangement has ended. Every device is now sold directly under the FIT Rife brand — the manufacturer that has designed and built this technology since 2012.

Something Natural is the official distributor of the FIT Rife range in South Africa.
