Gear Review: Lowrance Endura Sierra

The Lowrance Endura Sierra comes chalk full of street and topo maps.

Map Master

This unit comes with its own search engine and map library. Out of the box, the Endura Sierra has street maps and detailed topos for the entire Lower 48, and it includes thousands of waypoints, from ranger stations to pubs. Need more? You can upload GPS files, photos, videos, and mp3 files from your own personal library into the 4GB internal memory or insert up to a 32GB microSD card.

Everything is easily accessible from the 2.7-inch, color touch screen. In addition to waypoints and tracklogs, our tester recorded crisp 30-second audio clips of waterfalls using the unit's built-in microphone. Other notable features: digital compass, barometric altimeter, and a headphone jack to listen to audio files. Depending on how often we played media, we averaged 10-14 hours on two AA batteries. $550, 6.2 oz.;
