Inaccurate, slow

Completely inaccurate readings which seem to change from day to day (according to this compass my house faced northeast yesterday, today it faces west, and yes I’m using it properly). The needle moves too slowly too and takes a while to settle.

quechua c400 compass

well after buying a second one of these compasses after thinking about the replacement is better the needle is more stable ok its still in 5 degree graduations but as the mils are in 64.000 you can use the each mil line as a degree (17.77)mils to a degree and on a compass the mils have been rounded up 20mil increments I think .anyway I'm really pleased

Solid framework, easy to navigate, pretty accurate. If you want to have compass and not to fear caring it everywhere, it is a compass to have. I like the locking device, it doesn't get loose. The dial not too loose, and not too stiff. Just right to rotate and find angles and azimuths.

Solid, tough compass. I was looking for something tougher than orienteering compasses which have broken in my pack before, yet something slightly lighter than the the military camenga compass. This fits the description perfectly.

Готин е

Готин е компаса. Здрав е, мяташ го в раницата и не се притесняваш за него. Не е от най-леките, така че, ако си броиш грамовете в екипировката, не е за тиб. Има доста дълго (като време) колебание в стрелката, преди да застане точно на посоките.

Erfüllt seinen Zweck. Für's Wandern Gut geeignet. Ist gut verarbeitet bis auf den Drehring dieser ist aus Kunststoff. Ein Metal Drehring währe besser. Dann gebe es 5 Sterne.


Der kopass erfüllt seinen Zweck und ist gut verarbeitet

Magnifica precisión y estabilidad

Cuando la recibí lo primero que hice fue comprobar la precisión en los cuatro puntos cardinales, saque los rumbos, lo comprobé en el mapa haciendo triangulaciones sobre el terreno conocido, y el resultado fue excelente. El margen de error fue unos 80-130 m. tomando como referencia puntos que distaban a 16 Km. También hay que decir que use un transportador náutico en el mapa no la propia brujula.

Ideal para outdoor

Buena elección para llevar si falla el gps o para practicar con los mapas. Funcionando bien a -12 grados.


Justo lo que esperas y muy resistente.

What is a sighting compass?

Identical to a baseplate compass, this type of compass has a sighting glass for reading the compass and viewing the target to be reached. This model has a protective casing to protect the compass during intensive activities.

Make sure the compass is flat when using it:

Your compass must be flat to detect magnetic north correctly. For example, place your compass in the palm of your hand. When using a map, place the compass on the map on a flat surface.

What if your compass loses its bearings?

Use your compass away from magnetic sources or it could lose its bearings: high-voltage power lines, mobile phones, keys, metal objects, etc. Even another compass might affect the direction!

Oil bath - yes or no?

Rest assured: all Geonaute compasses are filled with viscous oil to ensure optimal performance.
