What is a Tensor Ring? — The Big Picture
A Tensor Ring is a closed copper loop where the two ends are not soldered — instead, a technique called friction-lock joins them. This specific construction is believed to generate a scalar wave field with unique properties not produced by ordinary soldered loops.
Tensor Rings were rediscovered in the 1990s by American researcher Slim Spurling, who studied the sacred geometry of ancient Egypt. He found that when copper wire is cut to the exact Sacred Cubit proportion (1.7718 inches per unit) and formed into a closed ring, the resulting field exhibits properties that practitioners worldwide have reported on for over thirty years.
This page is a complete reference covering everything you need to know about Tensor Rings — history, the physics behind them, sizes, how to choose, applications, and care.
📜 History — From Ancient Egypt to Slim Spurling
Roots in Sacred Geometry
The unit known as the “Cubit” has deep roots in ancient Egyptian civilization. It was used to build the Giza pyramids and many temples following sacred-geometry blueprints. The Royal Cubit, approximately 20.6 inches long, is recorded in inscriptions attributed to Imhotep and on architectural references for pyramid construction.
Slim Spurling discovered that Royal Cubit ÷ 12 = 1.7718 inches — a base unit that appears in the proportions of pyramids and recurring geometric structures in nature. When this unit is used to form a copper ring, the result is what users worldwide have reported.
Slim Spurling’s Discovery
In 1991, Slim Spurling experimented with shaping copper to this exact Cubit and discovered that the resulting ring produced a scalar field that practitioners have reported can:
- Make ambient EMF feel “neutralized” — without blocking signal
- Restructure water (observable through Magnetic Resonance Imaging studies)
- Amplify the effects of meditation and Sound Healing
- Protect a space from negative energetic patterns
Spurling published his work in the book “Spirit of the Rings” (2003) and co-founded Light-Life Technologies to make these tools accessible to the public.

⚛ The Science Behind It — What is a Scalar Wave?
Scalar Waves are a concept rooted in James Clerk Maxwell’s original electromagnetic equations (1865) and later in the experimental work of Nikola Tesla in the early 1900s.
Unlike ordinary electromagnetic transverse waves which travel perpendicular to their direction of motion, scalar waves are described as longitudinal — more like sound waves — and are claimed to have several unusual properties:
- They do not weaken with distance (no inverse-square law)
- They pass through obstacles such as walls and metal
- They are said to interact with water structure and DNA at the subatomic level
⚠ Scientific Honesty
We say this openly: there are currently no peer-reviewed mainstream-physics studies that prove the existence of scalar waves as Tesla and Spurling described them. The concept lives in the realm of fringe physics — Tesla performed experiments that were never fully published, and contemporary mainstream physics does not recognize “scalar waves” as a distinct phenomenon.
That said, independent researchers including Hans Becker, Glen Rein, and others have documented Tensor Ring effects under experimental conditions. This is not yet scientific consensus, but it is data that interested readers can study further.

📏 The 5 Main Tensor Ring Sizes — How to Choose
Tensor Rings are produced in different sizes based on different Cubit values. Each size is reported to produce a distinct frequency, and each is suited to a different use case.
1. Sacred Cubit — 144 MHz (the original)
- Unit length: 1.7718 inches (Sacred Cubit unit) — circumference is a multiple of this
- Reported frequency: 144 MHz
- Best for: Beginners, meditation, placement in the bedroom
- Character: A “neutral” wave — versatile, not specialized
This is the original size that Slim Spurling discovered first. It is the best starting point for anyone new to Tensor Rings.
2. Lost Cubit — 177 MHz
- Circumference: ~23% larger than the Sacred Cubit
- Reported frequency: 177 MHz
- Best for: EMF protection — Wi-Fi, smartphones, Smart TVs
- Character: A “finer” wave — said to neutralize EMF more precisely
Discovered later, in 1996, by Hans Becker, a colleague of Slim Spurling, while calculating the “missing” wavelength from the original Cubit set. Highly popular today because of EMF concerns in the digital era.
3. Slim Spurling 188 MHz (the original large size)
- Circumference: ~6% larger than the Lost Cubit
- Reported frequency: 188 MHz
- Best for: Water charging, large spaces (halls, gardens)
- Character: The “most powerful” wave — used for restructuring drinking water
Slim Spurling used this size as his primary tool in water research. Placing drinking water inside a 188 MHz ring for 30 minutes is reported to restructure the water, making it resemble natural mountain spring water in surface tension and clustering studies.
4. Solfeggio 528 Hz (the Love Frequency)
- Circumference: Calculated from the wavelength of 528 Hz
- Reported frequency: 528 Hz
- Best for: Sound Healing, theoretical DNA-related wellness practices
- Character: A “warm” wave — pairs well with Tibetan bowls, singing bowls, Solfeggio tuning forks
The 528 Hz frequency in the Solfeggio scale (associated with medieval Gregorian chant) is called “MI” — linked to DNA-related wellness claims and the wavelength of love. As with all Solfeggio claims, this is in the spiritual-tradition category, not peer-reviewed science.

5. Multi-Cubit Stacked (combined frequencies)
- Construction: Multiple rings joined together
- Frequencies: Combines Sacred Cubit + Lost Cubit + Slim Spurling 188 in one piece
- Best for: Practitioners with varied use cases, collectors, sound-healing teachers
- Character: Covers all common use cases in a single device
🔧 Why 99.9% Pure Copper — and Why No Soldering?
Pure Copper — Why 99.9%?
Copper is one of the best electrical and thermal conductors among the commonly available metals (second only to silver). This conductivity is believed to be essential for the scalar field to propagate cleanly around the ring.
But purity matters greatly:
- Brass (copper + zinc) — the zinc disrupts the field
- Bronze (copper + tin/lead) — additives degrade the wave
- Recycled or contaminated copper — inconsistent results from piece to piece
We use C11000 grade copper (Electrolytic Tough Pitch) with 99.90% purity — the same standard used in premium electrical wiring.

No Soldering — The Friction-Lock Technique
Soldering uses an alloy (lead, tin, silver, gold) to fuse two metal ends. From a physics standpoint, this alloy changes the electrical resistance at the joint, which is said to block the scalar wave traveling around the ring.
The Friction-Lock technique that Slim Spurling taught:
- The two ends overlap without soldering
- Mechanical pressure is applied with precision so the ends interlock and stay in place
- The scalar wave can travel uninterrupted through pure copper, end to end

🏠 Applications — 7 Ways to Use a Tensor Ring
1. Meditation and Yoga
Place a Tensor Ring on a primary chakra (root, heart, third eye) to deepen focus, or hold it during seated meditation. The Sacred Cubit 144 MHz is the most appropriate choice for general meditation work.
2. EMF Protection in the Bedroom
Place a Lost Cubit 177 MHz ring under your pillow or on a bedside table to neutralize Wi-Fi and smartphone fields.
3. Office and Computer Workspace
Place a Tensor Ring near your monitor or under your keyboard — the goal is to reduce the cumulative effect of EMF exposure during an 8-hour workday.
4. Water Charging
Place drinking water inside a Slim Spurling 188 MHz ring for 30 minutes — the structure of the water is reported to shift in ways that resemble natural spring water.
5. Sound Healing
Place a Tensor Ring on a Tibetan bowl during play — the sound waves merge with the scalar field, said to amplify the effect. Use 528 Hz for the gentlest result.
6. Whole-Home Protection
Place Tensor Rings at 7 key locations around the home (per Feng Shui principles) — creating a grid of positive energetic flow.
7. Travel
A small Tensor Ring (carried in a bag) is reported to provide energetic protection during travel — popular among those who work on the road.
🛒 Buying Checklist — 7 Things to Verify
- Is the copper 99.9% pure? — Ask the maker for a purity certificate
- Is the Sacred Cubit precise? — Should be 1.7718 inches, not rounded to 1.77 or 1.8
- No soldering — Inspect the join. Look for any alloy at the connection point
- Maker understands the Slim Spurling lineage — Articles, videos, or answers that reference the original sources
- Frequency testing — Verified with a Lecher Antenna or EMF detector before shipping
- Warranty — Maker is willing to replace if you’re not satisfied
- Reasonable price — Compare specs (size, purity, lineage) across multiple makers in the same category before deciding
🧼 Care Instructions
- Cleaning — Use mild soap and water, wipe with a soft cloth. Avoid harsh chemicals
- Patina — Copper darkens over time (this is normal and does not affect the field). Use copper polish if you prefer the bright finish
- Avoid salt water — Causes copper to corrode faster
- Store in a dry place — A paper bag or wooden box is ideal
- Never place in a microwave — Metal in a microwave damages the appliance
⚠ Cautions
- Pacemakers and medical devices — Maintain at least 30 cm (12 in) distance. Consult your physician before use
- Children — Small Tensor Rings have rounded but pointed wire ends; keep out of reach of small children
- Pregnancy — Use only Sacred Cubit (lightest field) and consult a physician beforehand
- Not a medical device — Tensor Rings do not replace medical care or treatment of any condition
