goTenna Pro vs PhorcysMOD

The goTenna Pro app is a tactical situational awareness application that pairs with goTenna Pro and goTenna Pro X2 mesh networking radio devices to enable mission-critical communications completely independent of traditional cell, Wi-Fi, or satellite connectivity. Users can download the goTenna Pro app to any iOS device, pair with a goTenna Pro or goTenna Pro X2 tactical radio, and then use the mobile device to communicate critical information like near real-time locations, share map markings, and send text messages while 100% off-grid. The app supports full interoperability with ATAK and the goTenna Android goTenna Pro app for seamless cross-platform mission coordination. goTenna Pro tactical radios have a 5W, tunable UHF/VHF output that can transmit critical data from your iOS device and also automatically act as relays that securely and anonymously “hop” messages across up to 6 devices to extend range.
