LifeRing 5.08 has the ability pre-cache maps of a certain area and at a certain zoom level, so you can quickly recall them later when you might not have access to internet-based or server-based maps. This is valuable when traveling to remote areas that have not already been cached from normal viewing or for mission planning to a specific area where internet access may intermittent. In the viewable area of LifeRing, go to the area and zoom level you want to pre-cache. Input 1-2 levels greater that your current zoom level and start processing.
