FAQs on Devices & Choosing

The coMra Pro 905 is the practitioners' choice. Its 905 nm laser penetrates deepest, produces faster action in serious injury and degenerative changes, and allows for less frequent treatments in clinical settings – a session structure that suits a practice schedule. It is equally recommended for home users who treat every day and want maximum effect per session.

No – the two are complementary, not interchangeable. The Palm Green handles emotional stress and nervous-system rebalancing; for recovery from serious injury, severe exhaustion or advanced disease, the infrared devices (Palm 2, Pro 980, Pro 905) working from the main coMra user guide are the right tool. The Harmony guide itself directs users to the infrared range for those situations. Many households run both: green for daily balance, infrared for physical recovery.

The Palm Green's 520 nm green laser is chosen for its strong calming effect on the nervous system – it helps the body shift out of fight-or-flight into a state of rest where regeneration happens. It is the device for everyday emotional stress, low sleep quality, exhaustion, low mood and the physical symptoms that ride along with them, such as skin irritation and digestive upset. It comes with its own dedicated Harmony user guide of systemic and local protocols.

Choose 980 nm for vitality, preventative care and everyday family use; choose 905 nm for recovery from serious injuries and severe chronic or degenerative conditions. Light at 905 nm is six times less absorbed by water (blood, lymph, intercellular fluids) than 980 nm, so more energy reaches deep tissue – giving stronger systemic effects and allowing less frequent treatments. That deeper reach is why the 905 nm Pro is the version practitioners work with.

The coMra Pro adds ultrasound as a fourth radiance alongside laser, magnetism and colour LEDs, and comes in two laser versions (905 nm or 980 nm); the Palm 2 combines three radiances – 980 nm infrared laser, magnetism and colour LEDs – in a compact device that fits in a handbag or pocket. Ultrasound brings faster recovery in serious injury or degenerative changes; without it, recovery proceeds at a steady pace with everyday treatment – which is exactly the Palm 2's role. The Pro also carries a larger battery (3000 mAh vs the Palm's 650 mAh).

Match the device to what you need it for. The coMra Pro 905 delivers deep-tissue, professional-grade support for serious chronic conditions and injury recovery; the coMra Pro 980 is the whole-family flagship for pain relief, tissue repair and preventative care; the coMra Palm 2 puts the same infrared therapy in a pocket-size device for treatment on the go; and the coMra Palm Green, with its calming green laser, is built for stress relief and nervous-system balance. All four combine low-level laser, magnetism and colour LED light – the two Pro models add ultrasound.
