Hannah Serrano on 05 Jul 12Get this high-sensitive GPS receiver that is reliable to ensure safety of dogs during wild hunting and fun. To maximize this device, you need to download your Garmin Astro 220 waypoints, routes, and tracks to your computer and upload them to your Garmin GPS. You can even back your own data and upload new data. You can also use your data over USGS topo maps and aerial photos to see the actual 1:24000 scale topographic maps from the US Geological Survey, giving you much more terrain detail than the maps that came with your Garmin. For poor GPS satellite reception can cause all sorts of errors in your Garmin Astro 220 tracks, you need track editing tools to correct spikes and blips caused by intermittent GPS multipath errors. You can even select an entire segment of your GPS track and drag it right back to its correct location on the map!
