I carry a Garmin GPSMAP on canyon trips, a Fenix watch on training runs, and a Garmin DriveSmart in the truck. After two years of overlap I can finally say what each one is actually for, and which one most people do not need.
| Device | Best For | Battery Life |
|---|---|---|
| Garmin GPSMAP 67i | Backcountry navigation | Up to 165 hours |
| Garmin Fenix 7 Solar | Trail running and daily wear | 2 weeks smartwatch mode |
| Garmin DriveSmart 66 | Road trips with no signal | Plugged in |
| Garmin eTrex 22x | Budget hiking | 25 hours |
| Garmin inReach Mini 2 | Satellite messaging | 14 days |
Handheld GPS Units
For real backcountry, a handheld is still the right answer. The Garmin GPSMAP 67i has a sunlight readable screen, glove friendly buttons, satellite messaging through Iridium, and 165 hours of battery in expedition mode. I dropped mine on slickrock in Utah and it kept tracking. The maps load on a memory card so you can carry topo for an entire region offline.
GPS Watches
A watch is what you wear when navigation is secondary to fitness data. The Garmin Fenix 7 Solar does breadcrumb routes well and the wrist heart rate is honest enough for training zones. For actual map reading the screen is too small. I use mine to follow a downloaded route while my eyes stay on the trail, but I still bring a phone or handheld for planning.
Car Navigation Units
Phones killed most of this category, but the Garmin DriveSmart 66 still earns a spot if you drive through long stretches without cell coverage. Western state road trips through Nevada, Wyoming, and the Dakotas are where this unit shines. The maps live on the device, so you never lose routing when LTE drops to nothing. Voice prompts are clearer than most phone speakers paired over Bluetooth.
Budget Handheld for Day Hikers
If you want a real GPS without spending almost 700 dollars, the Garmin eTrex 22x is the honest answer. Twenty five hours on two AA batteries, basic topo, no touchscreen to fail in the rain. I lent mine to a friend who had never used a GPS and he found a trail junction in fog with no instructions from me. It is not fancy and it does not need to be.
Satellite Communicators as a Companion
The Garmin inReach Mini 2 is not a navigation device first, but its breadcrumb tracking and two way messaging earn it a place in this list. Paired with a phone it becomes a capable navigator. Used alone, it is your lifeline for the SOS button. I carry one on any trip more than 10 miles from a road.
How to Choose
If you only hike day trails near cities, your phone with downloaded maps in Gaia or CalTopo is enough. If you go further or longer, buy a handheld first and a satellite communicator second. Watches are a luxury that complements but does not replace either one. Skip car GPS units unless you drive remote routes regularly.
Frequently asked questions
Do I still need a dedicated GPS if my phone works fine?+
On day hikes with cell coverage, no. For multi day backcountry trips, freezing weather, or kayaking where a wet phone is risky, a dedicated unit pays for itself the first time your phone dies.
Is a GPS watch accurate enough for navigation?+
For tracking and breadcrumb return, yes. For reading topo maps and route planning in the field, the small screen makes a handheld or phone a better tool.
