This GPS tracker is waterproof and supports both online and offline GPS trackers. For offline map, you just need to download the app on your phone first. Then use the app to download the offline map. I can use the app to create a team of up to 30 people. If I take it to Carter Lake National Park (no 4G coverage at all) I can use it to find another member on my phone (which also has a GPS tracker). When I press the SOS button, all the team members' phones start alerting. I can also send a message to a member of my team. This device is very useful for those who like to hike without a net or for young children to keep track of where they are.
