SteelPHASE sP01 Audio Enhancer.

Two prospectors got together and exchanged ideas about building a better audio enhancer. A collaboration between Pat O’Connell (electronics expert) aka SteelPat, and Nenad Lonic aka PhaseTech, and the steelPHASE Enhancer name was born. Field testing of various versions revealed different sound profiles (filters) would be beneficial on different detectors and different headphones, so it was logical to incorporate switchable filters into the final product. Very low noise circuitry for the clearest amplified sound allows you to hear the faintest of target signals. Combining a rugged yet stylish case and high quality electronic components, the sP01 was born.
