Garmin eTrex SE — Specs & Analysis
Manufacturer specifications, compared against every other navigation & electronics in our database. We do not test gear in the field — we measure, verify, and compare.
The eTrex SE is a handheld GPS built for simplicity and endurance. It runs on a rechargeable battery that lasts up to 168 hours in expedition mode, pairs with your phone for map downloads, and uses multi-GNSS for reliable positioning. No frills — just navigation that works.
Who Is the Garmin eTrex SE Best For?
Budget-conscious bikepackers who need long-lasting GPS for remote routes. If that describes your riding style, the eTrex SE should be at the top of your shortlist. It sits in the Navigation & Electronics category alongside 10 other products we track.
How It Compares
At 150g and $150, the eTrex SE is 95g heavier than the lightest option in this category (the Sigma ROX 11.1 EVO at 55g). It's also the most affordable option available.
The price-to-weight ratio comes in at $100 per 100g — a premium price point, but you're paying for quality, materials, and design that justify the investment for serious bikepackers.
What We Like
- +Exceptional battery life up to 168 hours
- +Multi-GNSS satellite support
- +Rugged IPX7 waterproof construction
- +Simple interface is easy to learn
Watch Out For
- −Low-resolution monochrome display
- −Limited mapping without phone connection
- −No cycling-specific metrics like cadence or power
The Bottom Line
We haven't scored the Garmin eTrex SE, and neither has anyone else we can cite. It's here for its verified specifications and dimensions, which is what the fit tools run on — a score is an editorial judgement, and we don't hand one out until someone has a basis for it. What this page can tell you is measured: 150g, $150, and how both sit against every other navigation & electronics product we track.
The price and weight above have not yet been checked against the manufacturer's own page. We are working through the catalogue and saying so as we go, rather than letting silence imply otherwise.
Specifications and dimensions come from the sources listed above. Where a page draws on first-hand riding, it says so.
How it compares
Against the 11 navigation & electronics we hold published specs for.
At 150g the eTrex SE is lighter than 1 of 10 alternatives we track, which makes it among the heaviest we track. The category median is 93g.
At $150 it undercuts 10 of 10 of them, against a median of $350. That works out at $100 per 100g — below the $368 median for navigation & electronics.
Weight and price come from published specifications. Cost per 100g is a blunt measure — it rewards light gear and says nothing about durability or whether the thing works — so treat it as one input, not a verdict.
