The Oregon 300 introduced touchscreen technology and Ordnance Survey maps to handheld navigation, and latest within the Oregon line is the Garmin 550t, which comes with a more detailed topographic map as standard and a constructed-in camera. The 550t's fundamental specification is very similar to the 300. It weighs the identical 193g with batteries, is ruggedised to resist knocks and drops, and is waterproof to IPX7 standards. Which means that it could possibly survive up to half an hour beneath a metre of water, so it ought to cope for those who fall in a river by chance or your tent will get flooded. There is a mounting backbone on the back for a karabiner, so you'll be able to attach the 550t securely to your clothes or backpack.
The two foremost new hardware options are the aforementioned camera and a triple-axis digital compass. The digicam sports 3.2-megapixels and is built into the back of the gadget in a similar way to a cellular phone. It offers autofocus, and takes acceptable pictures. Even in relatively poor light, it picks up a greater image than loads of smartphone cameras.
However the 550t's digital camera is not actually there to replace even your smartphone's photographic ability. Its true power lies in its geotagging function. That is something which is usually a little bit of a gimmick, significantly in camcorders. But within the Oregon it makes full sense. If you wish to take a visible record of the place you have been, a GPS-equipped digicam would require a minute or two to search out its bearings before location info could be stored along with your pictures. In distinction, assuming you have been using the 550t throughout your journey, it will be prepared for motion straight away.
Once you browse photos in the library, you possibly can easily name up a map displaying the placement of any that are geotagged, and this will likely be displayed on the installed topographic map rather than the very restricted ones offered by cameras and camcorders with this facility. Better of all, pictures present one of many vacation spot choices, so you can navigate to any geotagged picture, which is good for all method of applications, akin to naturalists monitoring the situation of vegetation they have discovered. Couple this with the 550t's potential to send data wirelessly to other Garmin Oregon devices, and you have a powerful extension of the outside GPS's usage.
The display has extremely poor viewing angles, but in follow that is only a problem whenever you're making an attempt to indicate something onscreen to someone else. More often than not, you possibly can angle the system so you can see quite clearly, although care needs to be taken to keep away from reflections. Because of the triple-axis compass, the Garmin 550t may be held at any angle and the map should remain accurately oriented with regard to the true world. It's because it detects the earth's magnetic subject in X, Y and Z directions. Devices with dual-axis compasses solely work reliably when held parallel to the ground.
