You can upgrade your Triangle at any time with the following optional licenses:

  • Quick Search
  • Fixed Intensity

In addition to the Hughson-Westlake method for AC threshold determination, users can choose the Quick Search method for threshold identification, which is based on the first response starting from the minimum selected level, or the Fixed intensity method, a basic screening test conducted at a fixed level of intensity.


The Triangle's lightweight and compact size makes it highly portable, and it comes with a dedicated soft carrying case for even easier transportation.

The Triangle's Lithium-Ion internal rechargeable battery supports more than 12 hours of continuous use.
