1. Locking knob that is friction adjustable for fast gps/lat/long transfers. This knob enables the two rulers to be fixed in any given separation which allows rapid determination of GPS position. [p]
2. Two sets of finger holes that enable finger tips to act as friction pads on the underlying chart and inform the navigator if the rule has slipped while plotting. [p]
3. Same features as standard size rules. The Paralock Plotter is only 7.25 inches long as opposed to the standard rule length of 15 inches, but its opening width is the same as standard rules.
