Too flimsy to cost $64.69.

The compass arrived with a bubble.
This compass, called Expedition 4, does not have the word Silva on it, so I fear that it is a knock-off.
It is similar to a compass I purchased in a Boy Scout store on Varick street in Manhattan, 20 years ago.
That boy scout compass has the words ‘Type 3 Made in Sweden’ on the bottom right-hand side. And it certainly did not cost $64.69.

Quizá la brújula más vendida de su categoría. Por algo será. Y de la marca más prestigiosa.

La bussola da trekking

Reviewed in Italy on October 19, 2014

A meno che non si vogliano fare gare di orienteering dove ogni grado fa la differenza, o vi dovete orientare nel deserto senza punti di riferimento, non vedo il motivo di usare una bussola più avanzata della Expedition 4-360: iperleggera, minuscola pratica e con tutte le caratteristiche di cui un escursionista medio avrà bisogno (e anche qualcuna in più): lente d'ingrandimento, metro fino a 10 centimetri, tacche per mappe da 1:25/40/50k, ghiera ruotabile con riferimenti fissi. L'ago fissato in aria e non in liquido non garantisce la precisione più assoluta, ma ripeto, all'escursionista medio non gliene frega niente.

La bussola è solida e rigida, mi è caduta già diverse volte ed è rimasta intatta. Affidabile in ogni occasione, non mi ha ancora dato problemi. Consigliata a tutti quelli che non hanno ASSOLUTAMENTE bisogno di una bussola professionale.

Haut degré de polyvalence

Reviewed in France on September 28, 2019

J'ai utilisé ce modèle de boussole lorsque j'étais dans les troupes de reconnaissance parachutistes.

En bref:
C'est la meilleure boussole que j'ai jamais eue ! (Comme boussole principale pour l'orientation à pied sans NVG (Night Vision Goggles).

En détail:
Les points positifs:
-Règle graduée de plus de 10 cm
Le mm est la plus petite unité utilisable pour mesurer une distance (avec précision) sur carte et donc connaitre la longueur du trajet. Le fait qu'elle soit grande permet de mesurer une distance générale ou non sans devoir reporter la règle et donc perdre temps et précision.
-Plusieurs Romers longitude/latitude
Les romers sont conçus en angle de 90° permettant une prise des coordonnées sans report ce qui donne gain de temps et précision.
-Aiguille aimantée, garage, couronne et flèche de direction de marche phosphorescents.
Ces caractéristiques permettent une lecture de cap de nuit. Ca ne vaudra jamais le plein jour mais le résultat obtenu est très bien dès qu'on est expérimenté.
-Loupe
Devient (malheureusement) nécessaire lorsque l'on prend de l'âge ou par forte fatigue.
-Œil de marquage
Jamais utilisé pour ma part mais pour le gens qui marquent leur carte/porte carte, ça permet d'être propre et précis.
-Œillet pour cordon
Permet d'accrocher une ficelle en vue de sécuriser la boussole. A Savoir, la magie de la nuit permet de faire disparaître plus ou moins tout ce qui n'est pas sécurisé.
-Solidité
J'ai utilisé ce modèle dans beaucoup de conditions y compris de très pénibles. Elle était solide, vraiment!
L'exercice Tenderfoot, long et complet, aura eut raison d'elle après plusieurs années d'utilisation.

Points a améliorer (Il n'y a pas de vrai point négatif):
-Aiguille aimantée
L'aiguille aimantée n'est pas assez phosphorescente pour être bien visible à l'oeil nu quand l'autre oeil utilise un monoculaire NVG en kit main libre. La DT 200 de chez Recta fait mieux le job à ce niveau là mais a malheureusement une couronne complètement phosphorescente ce qui éblouit fort...
-Les inscriptions sur la couronne
Ils devraient être à l'intérieur de la couronne ce qui les rendrait inusables. Il faut donc idéalement mettre sa boussole dans un petit linge, buff, plastique, couverture de survie quand on ne l'utilise pas. Ce qui la protège by the way des chocs également.
A savoir, je ne connais aucune boussole dont les inscriptions sont à l'intérieur de la couronne...

See You!
Maxime

Great quality, exactly what you’d expect

Reviewed in the United Kingdom on March 12, 2024

Perfect compass for hiking and trekking. Well made and has all the features you need. Only thing I would improve is the lanyard, it’s too short to allow you to take bearings and use properly with a map without taking it off. Easy fix though and other than that it’s great.

Toller Kompaß !

Reviewed in Germany on November 17, 2016

Verified Purchase

Lieferung und Verpackung sehr gut. Der Kompaß ist wie erwartet sehr gut verarbeitet und meiner Meinung nach seinen Preis wert. Er hat alle Features die ein Kartenkompaß haben sollte die Maßstäbe sind gut. Überrascht hat mich die Lupe die klar und gut vergrößert !
Fazit : mit diesem Kompaß macht man nichts falsch.

Nachtrag: eine Halteschlaufe liegt mit bei.Im Kompaß ist dafür eine perkte Aussparung vorhanden.
Hätte mir velleicht noch eine Schutzhülle dazu gewünscht.

Le bussole Silva non deludono

Reviewed in Italy on January 26, 2014

Verified Purchase

Possedevo già da circa 15 anni un vecchio modello base di bussola della Silva, che mi ha sempre accompagnato fedelmente e avrebbe potuto continuare a farlo, se non mi fosse venuta voglia di prenderne una migliore. Come per la precedente, l'ottima qualità costruttiva si nota subito. Ho apprezzato in particolar modo, oltre agli immancabili righelli in cm, la lente di ingrandimento, e le scale graduate che consentono di risparmiarsi tanti conti per gli ingrandimenti più comuni come 1:25'000, 1:40'000 e 1:50'000. Essendo tutti fatti a squadra poi si possono usare anche per calcolare il punto GPS sulle cartine dotate di reticolo.
Il prodotto era ben confezionato, ed era inclusa una cordina per appendere la bussola al collo e un piccolo libretto di istruzioni.
