Range Control; Changing The Range - Raymarine HSB2 Plus Series Owner's Handbook Manual

3.2 Range Control

The radar picture can be viewed at various scales. The shortest range scale
gives a maximum range of
to the top of the radar picture. The longest range scale gives a maximum range
of between 24 and 72 nautical miles depending on your scanner.
• The long range scales provide the best overview of your vessel's relation-
ship to land masses, weather fronts and large ship targets in or beyond
view.
• The short range scales provide greater detail of the radar echoes close to
your vessel, and should be used as you approach the coastline, harbour or
other vessels in the area.
The Pathfinder Plus Radar display includes concentric range rings, which you
can use to help you to judge distances on the radar picture. Their number and
spacing are adjusted automatically if you change the range scale. They can be
turned off (see Switching Radar Range Rings or Chart Grid On and Off on
page 2-13).
