Price — eTrex 10 wins for budget
The eTrex 10 costs $159.99, a full $76 less than the DriveSmart 66's $235.99. That difference buys two sets of AA batteries for years.
If you're on a tight budget, the eTrex delivers all essential GPS functions. The DriveSmart's premium is justified by its larger display and smart features.
Display — DriveSmart 66 dominates
The DriveSmart's 6-inch color touchscreen is a world apart from the eTrex's 2.2-inch monochrome LCD. Reading maps on the eTrex requires squinting.
The DriveSmart's capacitive touch is responsive and supports pinch-to-zoom. The eTrex uses physical buttons and no touch.
For car use, the large display is a safety advantage — you can navigate at a glance.
Battery Life — eTrex 10 lasts all weekend
The eTrex runs 20 hours on two AA batteries, compared to just 1 hour for the DriveSmart. This makes the eTrex ideal for backcountry trips.
The DriveSmart is designed to stay plugged into your car's power. Its internal battery only keeps settings.
Waterproofing — eTrex 10 is built for the elements
With IPX7 rating, the eTrex survives immersion in up to 3.3 feet of water for 30 minutes. The DriveSmart has no waterproof rating.
If you plan to use a GPS in rain, snow, or near water, the eTrex is the only safe choice.
Navigation Type — tied but different
Both use GPS and WAAS for accuracy. The eTrex adds GLONASS for better canyon performance.
The DriveSmart includes detailed North American maps with points of interest. The eTrex has a worldwide basemap but no detailed street maps.
For road navigation, the DriveSmart provides turn-by-turn voice guidance. The eTrex is for off-road waypoint navigation.
Best For — two distinct use cases
The eTrex is best for hikers, campers, and geocachers who need a rugged GPS. The DriveSmart is best for drivers who want a large, voice-controlled navigator.
If you do both, consider owning one for each purpose or a smartphone as backup.
Screen Size — DriveSmart 66's big advantage
At 6 inches, the DriveSmart's display is nearly three times larger diagonally than the eTrex's 2.2 inches. That means easier map reading from the driver's seat.
The eTrex's small screen is fine for basic waypoints but not for complex routes.
Voice Control — DriveSmart adds hands-free convenience
The DriveSmart 66 supports voice assist for hands-free destination entry and calling. The eTrex lacks any voice features.
Voice control is a safety boon for drivers, letting you keep your eyes on the road.
