Navigation and communication in one handheld
The GPSMAP H1i Plus brings detailed handheld navigation and inReach Plus satellite communication into the same device. Preloaded TopoActive mapping covers Australia and New Zealand, while multi-band GPS and multi-GNSS support handle positioning. High-resolution satellite imagery can be downloaded directly over Wi-Fi, with optional Outdoor Maps+ content available when you want to expand the mapping further.
Stay connected beyond mobile coverage
With an active inReach subscription, the H1i Plus can exchange text messages, photos and voice messages when mobile coverage is unavailable. It also supports interactive SOS through Garmin Response, location sharing and satellite weather, keeping the communication side of the device tied into the same handheld you are already using for navigation.
Flexible controls for the field
The 8.9 cm colour touchscreen is paired with physical buttons, so you can move between touch and button control depending on the conditions. Battery life reaches up to 145 hours in all-satellite systems plus multi-band mode, with longer Expedition modes available when maximum runtime matters. Front and rear cameras, an LED flashlight, built-in siren and voice control add useful functions without requiring separate devices for each job.
