The Garmin eTrex Venture HC / GPS is an essential for any outdoor excursion. It features a high-sensitivity GPS receiver for peak performance in any environment and includes 24 megabytes (MB) of internal memory, a detailed basemap and crisp color screen. The eTrex Venture HC's basemap contains lakes, rivers, cities, interstates, national and state highways and coastlines. The Venture HC also includes 24 MB of internal memory, so you can load waypoints and routes from the included MapSource® Trip & Waypoint Manager software and add map detail from Garmin's entire line of optional MapSource® mapping products. Its 256-color, sunlight-readable display makes it easy to distinguish map details — even in bright sunlight.
