GPS Watch vs Handheld GPS for Hiking: 179 g Apart

A GPS watch is the better choice for most hikers on marked or well-known routes: it weighs 32 to 63 g, records a whole trip and shows your line without leaving your wrist. A handheld GPS earns its 142 to 230 g when you navigate off-trail from a map for hours, need swappable AA batteries, or want satellite messaging in the same device.

How much heavier is a handheld GPS than a GPS watch?

The weights below are the manufacturers' own figures, linked per device in the last column. The COROS watches are weighed with the nylon band; the Apex 4 figure is for the 46 mm size (the 42 mm weighs 44 g). Both eTrex figures include the two AA batteries, and the GPSMAP 67i has a built-in battery, so every handheld number is the unit as you carry it.

Take the two devices most hikers actually shortlist for navigation. The Coros Apex 4 at 51 g is 179 g lighter than the GPSMAP 67i at 230 g, which makes the watch 78% lighter ((230 − 51) / 230 = 0.78); put the other way, the handheld weighs about 4.5 times as much (230 / 51 = 4.5). Between the Enduro 3 (63 g) and the eTrex SE (157 g with batteries) the gap is 94 g, or 60% ((157 − 63) / 157 = 0.60).

On a multi-day trip that difference is smaller than it looks, and also larger. Smaller, because 179 g on its own will not make or break a full pack. Larger, because most hikers wear a watch anyway: a handheld rarely replaces the watch, it gets added on top. The honest comparison is often 51 g versus 51 + 230 = 281 g. If you are trimming your kit, run both setups through the base weight calculator and see where that lands against your other cuts.

Wrist weight versus pack weight

Grams on the wrist are not felt the same way as grams in the pack. A 63 g watch is something you stop noticing after a day; a 230 g handheld lives in a hip-belt pocket, a shoulder-strap holster or the lid, and it is in your hand every time you check the line. That handling is the real cost, more than the weight: a watch is a glance, a handheld is a stop, unzip, look, put back.

Which lasts longer on a multi-day hike?

Manufacturer figures, all lab values that drop with backlight, cold and extra sensors:

• Garmin Enduro 3: up to 120 hours in GPS-only mode, 80 hours with all satellite systems and 60 hours in multi-band, with a Max. battery GPS mode of up to 210 hours, according to Garmin's Enduro 3 battery specifications. Garmin's solar figures assume use outside in 50,000 lux conditions, so don't plan on them under forest canopy.
• Coros Apex 4: up to 65 hours of All Systems GPS on the 46 mm model, the same 51 g size as in the table (the 42 mm model is rated at 41 hours), per COROS's Apex 4 page.
• Garmin eTrex SE: up to 168 hours in standard mode on two AA batteries, per the eTrex SE specifications.
• Garmin eTrex 32x: up to 25 hours on two AA batteries, per Garmin's eTrex 32x page. That is the shortest runtime in this list, so the 32x leans on spare AAs more than any other device here.
• Garmin GPSMAP 67i: up to 180 hours in GPS mode, or up to 165 hours with inReach tracking every 10 minutes, from a built-in rechargeable battery, per the GPSMAP 67i specifications.

Turn hours into hiking days by dividing by the hours you actually record. Our own assumption for a shorter hiking day is eight hours of recording: then the Apex 4's 65 hours covers about eight days and the Enduro 3's GPS-only 120 hours about fifteen. On long stages you will more often record 10 to 12 hours a day, breaks included. At that rate the Apex 4 lasts only about 5 to 6 days (65 / 12 = 5.4, 65 / 10 = 6.5) and the Enduro 3 about 10 to 12 days. The eTrex SE's 168 hours becomes 14 to 17 days, the GPSMAP 67i with tracking on 14 to 16, and the eTrex 32x's 25 hours just over two days per pair of AAs. All of this is before the watch spends battery on everything else between stages. On paper the handhelds win; whether a watch is enough depends on how many days lie between sockets. With 10 to 12 hour days, a stretch longer than five days already pushes an Apex 4 to its limit without a power bank.

The bigger difference is how you refill. Watches and the GPSMAP 67i charge by cable, so a week-plus trip means a power bank. The eTrex runs on two AA batteries that you can buy in a village shop and swap on the trail. Garmin's own advice for the eTrex 22x/32x is to use lithium batteries below freezing; we'd carry one spare pair of lithium AAs on any winter trip.

Can you actually navigate from a watch screen?

Yes, for following a line. No, for reading terrain. Mapping watches like the Apex 4 now carry on-device topo maps with trail names (COROS lists landscape and topo map layers), which is enough to see that you have left your GPX track and which way to turn at a junction. What a round watch face does badly is show context: how far the contour lines run, where the next stream crossing is, whether the ridge to your left is the easier way down. A handheld screen is bigger, and you hold it at reading distance rather than twisting your wrist.

One catch on the handheld side: not every handheld is a topo map device. The eTrex 32x comes with preloaded TopoActive maps, according to Garmin's eTrex 32x page. The eTrex SE manual describes no topo maps at all: its map settings cover tracks, waypoints and courses, not contour lines. If you want to read terrain on a budget handheld, that difference matters more than the 15 g between them.

When does a GPS watch make more sense?

• Waymarked long-distance trails. On a route with signposts and a downloaded GPX, you need confirmation, not route-finding. A 51 to 63 g watch does that.
• Stages with resupply and a socket every few days. Hut-to-hut and village-to-village trips never stretch a watch battery.
• Weight-counting trips. If the watch is already on your wrist, a handheld is pure added weight.
• Training and daily use. A watch also does heart rate, pace and daily tracking; a handheld sits in a drawer between trips.

Between watches, the trade is battery against weight. The Coros Apex 4 vs Garmin Enduro 3 comparison shows what the extra 12 g buys you.

When is a handheld GPS worth the extra grams?

• Off-trail and pathless terrain. When you are navigating from the map all day, screen size stops being a nice-to-have.
• Long stretches without power. Swappable AA batteries beat a power bank once the trip runs past a week without a socket.
• Remote solo trips. The GPSMAP 67i combines navigation with Garmin inReach satellite technology, so one 230 g device replaces a separate satellite messenger. That is the strongest argument for the heaviest unit in the table.
• Gloves and cold. If you hike in winter, try the buttons of both devices with your own gloves on before you buy.

For the handheld shortlist, the eTrex 32x vs eTrex SE comparison and the eTrex SE vs GPSMAP 67i comparison line the models up side by side.

The downsides of each, honestly

GPS watch

• A small screen shows your line, not the landscape around it.
• When the battery is empty, your navigation and your daily tracker are gone at the same time.
• Cable charging means a power bank and cable on longer trips.

Handheld GPS

• 142 to 230 g extra, usually on top of a watch you already wear.
• Every check is a stop: it lives in a pocket, not on your arm.
• A single-purpose device that you buy only for trips.

Our view: there is no single winner. If your trips are on signed trails with a resupply every few days, buy the watch and spend the saved grams elsewhere. If you go off-trail, solo, or far from any socket for over a week, the handheld (and in particular a model with satellite messaging) is the tool that matches the risk. Whichever you pick, a paper map and compass still weigh less than either and never run out of battery.

Frequently Asked Questions

Do I need both a GPS watch and a handheld GPS?

Rarely. On trails with signposts and a GPX track a watch alone is enough. Carrying both makes sense mostly on remote trips where the handheld also covers satellite messaging, as the GPSMAP 67i does, so its extra weight replaces a separate messenger rather than doubling up on navigation.

Can a phone replace both?

A phone with offline maps has the biggest screen of all, but it is also your camera, light and emergency phone, so our opinion is that it should not be your only navigation device: every hour on the map screen is battery you may want later for a call or a photo. Our suggestion is a watch for the line and the phone as a map backup in flight mode.
