Only DUET features Pulsar's unique, patented, approach to the issue of accuracy when temperature and echo reflection time varies. Both transducers fire together. By continuously monitoring the phase difference of the echoes, and because the distance between the transducer faces is known and constant, the speed of sound is continuously updated in real-time on the process. The resulting accuracy and stability are exceptional.
