SkyNext: DeLorme inReach Explorer

If you are ever flying over terrain that is not near populated areas, DeLorme's inReach Explorer is a piece of equipment that has the potential to save your life. This portable unit is connected to the Iridium satellite network, which means you can connect with emergency personnel, friends and family wherever you are in the world. ­Measuring 2.46 inches wide, 1.04 inches deep and 4.5 inches high (5.83 with the antenna) and weighing in at 6.7 ounces, the Explorer has a built-in GPS receiver. You can load a planned route into the portable unit and view it either on the screen itself or on an iOS device using the Earthmate app, which also allows you to get weather information and post to social media. The GPS location and tracking can also be shared with friends and family online through a feature called MapShare.

The Explorer has a wide temperature envelope with the ability to withstand extremes from minus 4 to 140 degrees F. Seaplane pilots will likely appreciate that the Explorer is water-resistant and has been submerged for at least 30 minutes in 1-meter-deep water during testing.

The unit allows you to send messages with up to 160 characters each. Most important, the Explorer has an SOS feature that connects to GEOS — an emergency response center that works around the clock to help you stay safe and get home. The Explorer allows you to send messages to the responders to provide details about the emergency. The Explorer cost is $379.95 and subscriptions range from $11.95 to $99.95 per month, depending on the level of service.
