Understanding the differences between digital solid state and analog spark gap PEMF machines

Analog spark systems create high intensity, extremely sharp, pulses which are between nano- and microseconds and the amount of energy inside each pulse is very small. These pulses are so fast that the quantity of energy transferred into the body mass is only minimal and the main effect is muscle movements.

Looking just at Gauss values can be misleading because the inducted energy effect of the digital Flash pulses is significantly more effective than analog spark pulses because they are thousands of times wider than spark pulses and contain much more energy.

In addition, the way an analog spark gap chamber discharges is dependent on the distance between the ionizing electrodes inside and the humidity of the surrounding area on which depends the ignition moment and the discharge of the high voltage capacitor.

This explains why the intensity of analog spark PEMF machines is unstable, delivering uncomfortable stimulation pulses that are unstable, and combined with the sharp pulses prevents using higher pulsing settings. Even if these devices are able to create high Gauss values, these pulses often become too painful and cannot be used at all.

The solid state digitally computer-controlled Flash systems will always create equal magnitude pulses, increasing the level of the pulses in gentle steps and allowing for the settings of each level to feel comfortable. The Flash systems simultaneously transfer the highest possible energy into the body mass without painful or sudden impulses (that do occur in analog devices).

In addition, analog spark systems create ozone which is damaging for the lungs if the PEMF device is used in a room which is not sufficiently ventilated.

Analog spark systems are also known for yearly very expensive repair requirements obligating shipping of the unit to the manufacturer for replacement of the spark electrodes, which often leaves customers with no unit for many weeks. The owner of such an analog system ends up paying for the repair costs as well as for shipping both ways.

Contrary to analog spark units, digital PEMF devices do not require any service and contain no mechanical or electronic parts that need to be replaced!

Testimonial just received: We currently have two Magnawave Pulse analog machines with zoom paddles, large loop coils, butterfly coils, XL Wings and hoof box. Magnawave maintenance and repair has been ongoing, with units returning to Magnawave at least annually. We had one unit that was actually returned to us without completing the paid repairs, then having to be sent back two more times in the following 60 days, just to get the required parts replaced. We have had three out-of-warranty replacements of faulty coil-cable applicators, with most failing at the cable-to-coil unions (no repair available). Shipping, insurance and service pricing are significant. We have fought the erratic pulse intensity for years, replaced power supplies, spark chambers, rheostats, timers, you name it, and we are very careful with our equipment.

Both Travel-Flash devices are digital, computer-controlled PEMF systems and offer much more advanced technology than that of any other manufacturer of PEMF machines in the world. In addition the Travel-Flash machines are competitively priced and much less expensive than any other "comparable" PEMF device.

The Travel-Flash PLUS has an even stronger pulse generator than the already strong Travel-Flash, allowing for the use of a second applicator without impacting the high intensity when using both outputs simultaneously. Using only one of the two outputs creates extremely strong pulses while using both outputs at the same time only decreases the applicator power by around 20% for each applicator [not 50% like for analog spark devices] and in a Helmholtz configuration the full intensity between the coils is obtained.

Conclusion: when seriously looking into the differences between the digital Flash and obsolete analog spark PEMF machines it is unavoidable to come to the conclusion that the analog spark devices available on the market are not only far overpriced, but also technically incomparable to the much lower priced superior Flash devices.
