Product Information

Protection against the adverse effects of Electromagnetic Radiation (EMR) while out and about.

Benefits of The Traveller

✅ Stops the negative effects of all EMFs for anybody within its protective bubble

✅ Enjoy the peace of mind from knowing you are protected.

The Traveller is a multifunction device that covers the wearer against the wide range of EMFs we encountered wherever we are; whether inside or outside. or travelling by air, train, or car etc.

Protection against the EMFs that are all around us is as necessary and important while you are out and about, as it is to protect yourself with a Harmony/XL in your home.  For example, the EMF exposure we experience on a 7 hour long haul flight has the equivalent adverse effects as having an X-ray.  The Traveller compensates for the potential effects of Wi-Fi, WiMAX, Bluetooth, 2-4G, sub-6GHz 5G frequencies, DECT and wired telephones, relay antennae, satellite communications, low to very high voltage electrical networks, geo-biological disturbances, microwave ovens, low consumption light bulbs, smart meters and other similar Smart technology, CPL (Carrying Currents Online), transport (car, plane and train) .

All Comosystems products use CMO (Compensating Magnetic Oscillator) technology that is activated by the polluting EMFs surrounding it.  Activation generates a compensating signal that piggybacks on top of the harmful EMFs thereby stopping their adverse disruptions to our normal biological processes. In short, wearing a Traveller makes EMFs biocompatible within its 1.5m range in all directions. You can put it on your bedside table when staying away in hotels etc to cover you whilst you're not wearing it in bed.

This means we live in harmony with technology, without interfering with the function and benefits we derive from our WiFi etc.

NB: Whilst the Traveller multifunction protection covers the broad source of electromagnetic pollution described above, we still advise you to use CMO devices with your mobile phone and laptop/tablet that are used in frequent close contact with your body. We recommend that you equip mobile phones with an Easycall, and use a PCZone for each laptop or tablet - especially if used outside the protected area.  We recommend one of the HarmonyCMOs to protect you at home/office. 

Check out the Bundles category for maximum surveillance protection and EMF protection from multiple devices in combination.


The Traveller is designed to be worn close to your body; in your pocket, wallet, or hung on a necklace or lanyard as a pendant. A snap hook-ring accessory is provided so you can attach it to a belt buckle, a key ring, or wherever. for your convenience.


The Traveller has been designed to provide effective compensation for the potential effects of your immediate surroundings. The protection bubble thus generated has a diameter of about 3 meters (ie 1.5m in all directions).

Note: the range of influence the CMO technology is given as an approximate indication. There may be slight variations according to the situation where it is in use.  The figures provided are the limit of effectiveness of the corrective effect which has been estimated by the RAC method (auricular-cardiac reflex).

Instructions on how to set up and use your CMO devices once you have them can also be found here.


The Traveller weighs 34 grams with a diameter of 45 mm, and a 9 mm thickness.
Composition: CMOs are passive magnetic oscillators, operating without energy input: they activate in the presence of artificial electromagnetic fields.
The aluminium shell is made of 100% aluminium.
Chemical composition of the active solution: microcrystalline saline solution treated electromagnetically.
