This relates to the power of the field generated by the device - not it's ability to perform. (the field has a stronger feel) High strength fields are best suited to high end users in high-risk EMF environments with users being exposed to wifi and smart phones and smart meters and should not be used by people with EMF sensitivity, the sick or pregnant women, as a detox maybe too sudden for some people. All the Tesla Gold Series is in this high strength category.
This relates to the coverage of the field generated by the device. Tesla Silver and Gold Series Plug-In devices (designed for large spaces, business and commercial areas) have a 90 meter coverage. Where as the Tesla Large Area has a 180 meter coverage.
All Tesla Portable models and the Large Area models use alloy cases, some touting alloy end caps with switches and others ABS parts as well. These are super durable and will outlast many battery replacements. This icon is used with both case types.
These high impact ABS (plastic) cases are used for all of the Plug-In models. These are all black in color.
This relates to the coverage of the field generated by the device. Tesla Gold Series portables have a 6 meter coverage area, except for the Mini which has only 3 meters coverage.
All our portable models come with Lithium Manganese Dioxide batteries. These are special Lithium batteries which are known for their safety and stability. All batteries are custom made to our specifications, replacements can be ordered through our website.
Note: Batteries are not covered under warranty as we cannot guarantee the life expectancy and temperature in which these batteries maybe used. Do not leave your Blushield in direct sunlight as this will heat up your batteries causing the life of them to be somewhat reduced. Dropping your Blushield on a hard surface may cause the battery damage and your unit to stop working.
