How do I choose between the V1, V2 Pro, and V3 Max?
The fastest way to decide is to think about how much control you want and how deep you want to go.
V1 Classic - for simplicity. One frequency (7.83 Hz), one button, weeks of battery. Set it and forget it. Ideal if you want grounding without the learning curve.
V2 Pro - for explorers. Adjustable from 0.01 to 999.99 Hz, sine and square waveforms, digital display. Ideal if you want to dial in different frequencies for different goals throughout your day.
V3 Max - for going all in. The full kilohertz range up to 9,999.99 Hz, 5 preset buttons, up to 24-hour battery, and access to high-frequency territory above 1,000 Hz that no other portable device reaches. Ideal if you want maximum range and zero compromise.
I'm new to frequency technology, where should I start?
Start with the V1 Classic. It runs on the Earth's natural 7.83 Hz frequency, has the longest battery life of any of our devices, and requires no setup beyond pressing the power button. Most users notice a difference within the first 1 to 2 weeks of consistent use, and you can always upgrade to the V2 Pro or V3 Max later if you want broader access to the spectrum.
I want to experiment with different frequencies for sleep, focus, and meditation. What do I need?
The V2 Pro is built for that. The 0.01 to 999.99 Hz range covers the most commonly used frequencies for sleep (delta and theta ranges), meditation and creativity (alpha), focus (beta), and gamma applications. Switchable sine and square waveforms let you choose between gentle continuous fields and more energizing pulses depending on the time of day. Most experimenters find the V2 Pro covers everything they need.
What does the V3 Max give me that the V2 Pro doesn't?
Three things, mainly. First, range. The V3 Max reaches 9,999.99 Hz, ten times the V2 Pro's ceiling, opening up the full kilohertz range where many advanced bio-energetic and structural protocols sit.
Second, presets. Five physical preset buttons mean you can save your most-used frequencies and switch between them with one tap, no scrolling.
Third, battery. Up to 24 hours on a charge, which is roughly double the V2 Pro's runtime.
Can I own more than one device?
Many customers do. A common setup is V1 Classic in the bedroom for overnight grounding, and a V2 Pro or V3 Max in the home office or living room for daytime variation. The fields don't interfere with each other and can run simultaneously in the same home.
Is there a comparison chart?
Yes. You can view a side-by-side comparison of the V1 and V2 devices at theschumann.com/pages/compare-products. V3 comparison coming soon, however you can learn about all the differences on the individual product pages.
