What affect speed in GPS use?
Before you buy a portable GPS system, GPS watch, or wristop computer, think about how and where you plan to use it, and consider which of these factors are the most important:
- Style: If you will be putting a portable GPS system to the test in outdoor activities, a wristop computer might be the best choice. If you aren’t using a wrist GPS, look for a design style that fits easily into a pocket.
- Size: Larger portable GPS systems have specific buttons for each feature, which can make them easier to use, and they are often less expensive than the smallest portable systems. However some small systems do feature oversize screens for better visibility.
- Speed: The more channels your portable GPS system has, the faster it will refresh. If speed is important to you, compare two models of GPS systems and see which one is faster at reloading and reconnecting to satellite signals.
- Spending: The more features you have on your GPS watch or wristop computer, the more you’ll pay. If your hiking and camping plans mainly include day trips or areas with maintained trails, you might not need to spend additional money on an altimeter feature. On the other hand, if you are a frequent backcountry adventurer, the extra money might be worthwhile.
