The Oregon 450t has all the features expected of a high-end GPS receiver. These include a large touch screen with a user-friendly interface; 3D map viewing; built-in topographic maps; wireless sharing with other Garmin Oregon and Colorado GPS receivers through Bluetooth connectivity; paperless geocaching ability; barometric altimeter; and the capability to save multiple user profiles and settings. In addition, navigation is accurate and precise, and viewing angles are good. The 450t can run for about 16 hours on its two AA batteries. In addition, it is ruggedly built and waterproof to a depth of 3 feet, meeting IPX-7 waterproof standards.
Navigating is easy with the Oregon 450t. It can hold up to 200 routes with a maximum of 1,000 waypoints, and save up to 200 tracks with 10,000 points. A triaxial compass means that users don't have to worry about holding the GPS receiver level. However, as noted by reviewers such as Rich Owings at GPSTracklog.com, the increase in convenience over a two-axis electronic compass comes at the small expense of a more complicated calibration process, and that must be performed each time the battery is changed.
Although he calls the Oregon 450t's interface "about as intuitive as they get," Owings points out that the many options on the screen may be overwhelming for a first-time user. The main menu is spread over five screens, which the user can customize by creating new profiles, each with different menu setups and settings. Comments by owners posting at Amazon.com indicate that the Oregon 450t's users make full use of this facility.
The Oregon 450t comes preloaded with topographic maps of the United States, which are at 1:100,000 scale. Some reviewers question whether this is worth the extra cost over the base model Oregon 450 (*Est. $300), which is identical save for those preloaded maps. For example, GPSTracklog.com says that users can access plenty of free topographic maps at a 1:24,000 scale from the Internet. However, reviewers at Amazon.com comment that these smaller scale maps lack details, such as unpaved roads and trails, which are useful for off-road and backwoods navigating. A BirdsEye aerial 3D map feature allows users to download 3D imagery maps of places including state, national and local parks, and lakes, rivers and trails. You need to pay an annual fee (*Est. $30 per year) to access this feature, however, and that draws some negative owner feedback.
Geocachers can download site details directly from the Internet into the Oregon 450t instead of having to enter them manually, a feature that's well received. Users can also access descriptions of a site, with hints about its location and logs from other searchers, and upload and log their own attempts at finding the site. One drawback identified by the reviewers is that you need a premium membership to a third-party site to fully utilize these features.
The Garmin Oregon 450t brings photos into the GPS experience with a picture viewer enabling users to share uploaded pictures. It also has an interesting photo navigation option where users can upload geotagged photos of locations and navigate to them. The Oregon 450t, however, lacks a camera. People who want the ability to take their own geotagged photos need to purchase the slightly more expensive Garmin Oregon 550t, which is identical to the Oregon 450t model but with a 3.4 megapixel autofocus camera.
GPSTracklog.com has a great review of the Garmin Oregon 450 -- identical to the Garmin Oregon 450t except for the addition of topographical maps. TopTenReviews.com does evaluate the Oregon 450t; while the write-up is based more on specifications and features than testing, it is still helpful. For user opinions, head to Amazon.com.
