Please note our Otto 128 is currently in a green velvet carrying bag with drawstring tie.
The 128 Otto Tuner is especially effective, but not limited to:
-
Rib heads – The rounded ends of your ribs that connect to your spine.
-
Thoracic vertebra – The middle back bones that ribs attach to.
-
Sternum – The breastbone in the center of your chest.
-
Iliums – The large, wide bones at the top of your hips (part of your pelvis).
The Otto 128 Hz Weighted Tuning Fork is traditionally applied to bony structures of the body, where its vibration can be easily perceived. Common application areas include the rib heads, thoracic vertebrae, sternum, iliums (hip bones), sacrum, spine, shoulders, knees, ankles, wrists, and feet.
As with all tuning forks, avoid applying directly over recent injuries, fractures, areas of active inflammation, or sensitive medical conditions.
Attaching the Gem Foot
Place the Gem Foot at the base of your weighted tuning fork stem.
Using the enclosed Allen wrench, gently tighten the small screw until secure.
Do not over-tighten—this may strip the screw.
Tighten just enough so the Gem Foot stays in place while still allowing easy removal.
How to Activate
Hold the stem of the tuning fork or the Gem Foot in your hand.
Lightly tap the weighted end against a semi-soft surface (knee, outer palm, or an activator).
The fork will begin to emit a clear, steady vibration.
How to Use
Place the Gem Foot on the desired area of the body.
Hold in place (approximately 30 seconds).
Move to the next point, spacing placements about 3 inches apart.
