I use a Delorme inReach SE when sailing. If the device is ON it will update an online map with my position every 10 minutes. It also allows two-way text communication and SOS service. For more info, click on the banner below.

Keep in mind, I only use the inReach while out sailing around, and I'm not always out sailing around. Check with me for sailing schedule 😉
