The High Pass filter usually yields the best presentation of the collar echoes.
After selecting the appropriate filter, the markers are displaced horizontally using the left/right arrows until the
leftmost marker is aligned with the first identifiable collar echo:
Then the spacing of the collars is adjusted (by pressing the UP and DOWN buttons) until the majority of the
markers are aligned with collar echoes. This yields a joint count of 17.21 joints per second in the specific interval
between 1 and 2 seconds.
