Which GPS you use depends on your needs, handheld GPS are great for walking in remote National Parks along with your Personal Locating Beacon (PLB) an essential bit of safety kit. I have used handheld Garmin GPS for many years both for hobby and professionally and have always been pleased with them, these days phones and iPads come with neat apps that duplicate GPS function, but these apps sometimes are not as versatile and robust as a dedicated handheld GPS.
GPS in cars are a different game. I have used Garmin's for many years as my car GPS and to find your way around cities, major towns and connecting highways they are fine. Especially if you buy one with lifetime map updates, My Last one I bought from J and B Hi Fi for $95. I specifically asked for last years model (to get better deal), but with lifetime map upgrades. The map upgrades are particularly useful in places like Sydney where the road system changes every few months. However, the Garmin car GPS are like most other car GPS next to useless in the bush and on remote roads.
This has prompted me to think about buying a Hema HN7 they are about $620, but now have a 150K vector base map of all of Australia, which nicely covers the bush. They also have specialist Hema maps loaded and can download raster maps of up to 25K resolution. In all a good system for remote areas. Generally, the preloaded maps would do most of us in remote places in our vehicles. I now need to just commit on spending this $ much on a GPS.
