Silva
Sweden, 1933 — the brothers who invented the liquid-filled compass, and then lost the right to sell under their own name in America for forty-five years.
Three Swedish orienteering brothers and a machinist worked out how to damp a compass needle in liquid so it would settle while you were running. That was 1933, and it is the reason every compass you have ever used works the way it does. Silva still makes them — about twenty-five land models and sixteen marine — alongside a headlamp line that goes back to 1935. What it does not make, despite marketing a "Professional" range, is anything certified for a hazardous area.

What we'd reach for
- Expedition seriesThe serious navigator's compass — clinometer, magnifier, declination adjustment. Expedition S adds a sighting mirror, Global adds a needle that works in all three magnetic zones.
- Ranger seriesThe one most people should actually buy. Ranger, Ranger S, Ranger SL and Ranger Global cover almost every real use.
- Arc Jet and Spike JetThumb and wrist compasses built for competitive orienteering. This is the founding sport, still served, ninety years on.
- Trail Runner Free 2450 lumens with the battery in the headband and no cord at all. The running staple, and the design idea the rest of the line is built on.
- Free series900 through 3000 lumens on one lamp head with four battery sizes. Buy the light once, size the battery to the night.
- Exceed 4XT2,000 lumens with a 10.5 Ah pack — 60 hours low, 12 hours high. For ski touring and long nights on a bike.
- Ignite10,000 lumens, 96 Wh, eight LEDs, and seven hundred and eighty dollars.
- Marine compassesFixed-mount boat compasses from the 58 Kayak up to the 125 series. The marine range dates to 1981, and it is a whole category most gear writers never notice.
The problem with a compass is that the needle will not sit still.
Walk with it and it swings. Run with it — which is what orienteering is — and it is useless. In 1933 three Swedish brothers who raced, Alvar, Arvid and Björn Kjellström, worked with a machinist named Gunnar Tillander and solved it by suspending the needle in liquid so the fluid damped the swing.
Every compass you have ever used works that way because of them.
Two years later, in 1935, came the Zeiler headlamp. Lighting at Silva is not a modern diversification into a growth category. It is ninety years old.
The forty-five years Silva was not Silva in America
This is the fact that will save someone money on eBay.
Björn Kjellström built the American business himself — La Porte, Indiana in 1946, Toronto in 1948. In 1973 that US entity was acquired by Johnson Wax Associates, later Johnson Outdoors.
In 1996 the Swedish company ended the arrangement, bought Brunton, and had to sell its own compasses in North America under the Nexus name. Johnson kept the right to sell compasses branded Silva in the US and Canada, made by whoever it chose. The two sides went to court in 1998 — though that particular ruling decided only jurisdiction and venue, not who really owned the mark.
It ended on 4 January 2018, when Silva bought the North American rights back after forty-five years.
So: any “Silva” compass sold in the United States or Canada between 1973 and 2018 was a Johnson Outdoors product, not this company’s. Old reviews, old stock, and the used market all sit on the wrong side of that line. If you are buying a vintage Silva in North America, you are probably not buying a Silva.
What “Professional” does not mean here
Silva sells a Professional range — FreeLight, SmartLight, RoughLight, HelmLight — described for “industry, construction, rescue, forestry, service and other tasks where light, comfort and dependable function need to last through the full shift.”
We read that page carefully looking for a certification. There is no ATEX, no IECEx, no intrinsic-safety rating, no Class I Division 1, no EN safety standard of any kind. The claims are robust construction and IP ratings.
That is fine for construction and forestry. It is not fine for a classified area, and “Professional” is doing the same work here that “industrial headlamp” does at Fenix — implying a certification that isn’t there. For an explosive atmosphere the brands that actually hold the paperwork are Ledlenser, Streamlight, Princeton Tec and, in three specific models, Nitecore.
The cordless idea
The Trail Runner Free 2 puts the battery in the headband rather than in a pack on the back of your head with a cable between them. No cord to snag, no cable to fail, weight distributed front to back.
The Free series extends it properly: one lamp head, four battery sizes from XXS to M. Buy the light once and size the power to the night — 900 lumens for a run, 3,000 for a ski tour.
That is a better product architecture than most of this category manages, and it is the reason to look at Silva for lighting rather than just for compasses.
What they don’t make
A bike light. Silva sells a Free Bar Mount Kit so you can put a headlamp on your handlebars. There is no standalone front or rear light, no StVZO-approved commuter lamp, and no rear position light. If you need a road-legal bike light, this is the wrong brand.
Their own products, strictly speaking. Silva states plainly on its own sustainability page that it “does not have its own production and is therefore dependent on various suppliers and subcontractors,” largely in Asia. Suppliers are required to meet Amfori BSCI and BEPI standards. They are not named.
Where Silva fits
Navigation. Around twenty-five land compasses and sixteen marine — the marine range has been running since 1981. Expedition for serious work, Ranger for most people, Field for schools and youth groups, Arc Jet and Spike Jet for racing.
Battery-free navigation is a short list, and Suunto is the other name on it — founded in Finland in 1936 out of the same sport, three years after Silva. Compare the two directly rather than assuming. On the water, a Silva fixed-mount compass and a Steiner 7x50 with a compass in the glass are the pairing that needs nothing from a battery at all.
Trail and ultra running. Trail Runner Free 2 and the Free series.
Ski touring and night riding. Exceed 4XT, and the Ignite if you have lost all sense of proportion.
Not for: hazardous locations. Bike commuting. Anyone who thinks they are buying a Swedish family company — Silva has had four owners since 2006 and is currently held by Verdane, a growth-equity investor, having merged with Primus in 2023.
Why we rate them
They invented the thing. Not “innovated in the space” — invented the liquid-filled compass, in 1933, and it is still how every compass works.
They never left orienteering. The Arc Jet and Spike Jet are competition instruments for a sport almost nobody outside Scandinavia takes seriously, and Silva still makes them.
Five years on compasses and headlamps. The best warranty in this lighting group by a distance — BioLite gives one year on its flagship. Read the limits: original purchaser, and claims must be processed in the country of purchase.
Where Silva sits across the three disciplines: rope rescue, rope access, fall protection — three jobs, one pile of gear.
