73R is the perfect combination compass. It can be installed in any inclination or position with a bracket that allows for fast and easy removal. The handle makes it useful as a sighting compass; simply remove the compass from its bracket and sight the mark to determine the bearing. Tactical compass scale on the vertical part of the card. 73R is also easy to remove from bracket for security purposes. Detecting wind shifts may be the tiny difference between winning and loosing. Silva’s tactical scale grades from 0-20 and the figures correspond on port and starboard tack. If the reading on starboard tack is 2 the reading on port after tacking should also be 2. In this way you only have to remember one figure. This is a great benefit in triangular course sailing where racers need to watch the wind shifts, rather than their actual course.
