vis\u00e9e\u00a0:<\/p><ul class=\"spip\"><li>Garder la boussole horizontale, sinon l\u2019aiguille va se coincer dans le cadran et n\u2019indiquera plus le nord.<\/li><li>Cr\u00e9er une lucarne de vis\u00e9e \u00e0 l\u2019aide de son index et de son annulaire, comme indiqu\u00e9 sur le sch\u00e9ma.<\/li><li>Faire attention \u00e0 bien garder l\u2019alignement entre l\u2019aiguille et les lignes du cadran\u00a0: il faut incliner l\u00e9g\u00e8rement la boussole pour voir en m\u00eame temps le rep\u00e8re de vis\u00e9e et la position de l\u2019aiguille.<\/li><li>Ne pas prendre comme rep\u00e8re de vis\u00e9e un objet qui pourrait se d\u00e9placer (vache, tracteur&#8230;). De m\u00eame, la nuit, ne pas prendre pour rep\u00e8re une lumi\u00e8re d\u2019origine inconnue\u00a0: si cette lumi\u00e8re est due \u00e0 des phares de voiture, il y a un risque d\u2019avoir des surprises\u00a0!<\/li><li>Choisir un rep\u00e8re le plus \u00e9loign\u00e9 possible de fa\u00e7on \u00e0 r\u00e9duire les erreurs de vis\u00e9e.<\/li><li>En for\u00eat ou de nuit, il est pr\u00e9f\u00e9rable de travailler \u00e0 deux\u00a0: le premier part devant et se transforme en \u00ab\u00a0rep\u00e8re mobile\u00a0\u00bb. Il suit les indications du deuxi\u00e8me, qui tient la boussole. De nuit, le \u00ab\u00a0rep\u00e8re mobile\u00a0\u00bb peut signaler sa position \u00e0 l\u2019aide d\u2019une lampe \u00e9lectrique.<\/li><\/ul><p>Il reste \u00e0 aller jusqu\u2019au rep\u00e8re choisi.<br class=\"manualbr\" \/>L\u00e0, il est conseill\u00e9 de faire un contr\u00f4le en visant avec la boussole le point que l\u2019on vient de quitter\u00a0: si le trajet est bon, et si le r\u00e9glage de la boussole n\u2019a pas \u00e9t\u00e9 modifi\u00e9, l\u2019aiguille aimant\u00e9e doit indiquer exactement le sud du
