1 ABOUT THE RETICLE The vertical scale (reticle) visible through the right half of the binocular allows you to calculate distance to an object if you know its height, or to calculate the height of an object if you know its distance from you. Detailed instructions for using the reticle are provided in later pages of this manual.
2 About The Ranging Reticle There are vertical and horizontal lines on the reticle (Fig. 1). Each minor division on both vertical and horizontal lines represents 5 mils and each major division represents 10 mils (one circularity angle=6400 mils.
3 Upper and lower angle measurement: Upper and lower angle means the angle included between any two targets (or two ends of a target) against the vertical line on the reticle.
4 When the target’ s upper and/or lower limits are larger than the mils on the reticle, it can be measured in steps and the angle can be obtained by summing up the value of each step. (The process will be similar to the one that is discussed in the linear measurements section above.
5 How to measure a target’ s size (height and width) using azimuth readings (both models) According to the formula for distance measurement, you can calculate the height using: H = D x w . When measuring the size, you rst estimate the distance to the tar get, then measure the azimuth or upper and lower angle.

7 LE RÉTICULE L ’échelle verticale (réticule) visible à travers le côté droit des jumelles permet de calculer la distance jusqu’à un objet de hauteur connue ou de calculer la hauteur d’un objet dont la distance est connue. Des instructions détaillées d’utilisation du réticule sont fournies plus loin dans ce manuel.
8 Le réticule de télémétrie Le réticule comporte des lignes verticales et horizontales (Fig. 1). Chaque graduation mineure sur les lignes verticales et horizontales représente 5 millièmes et chaque graduation majeure 10 millièmes .
9 Mesure d’un angle en hauteur : L ’angle en hauteur est l’angle séparant deux cibles quelconques (ou deux extrémités d’une cible) par rapport à la ligne verticale du réticule. La mesure de l’angle en hauteur est semblable à la mesure de l’azimut.
10 Lorsque les limites supérieure et inférieure de la cible dépassent les graduations du réticule, la mesure peut se faire par par - ties et l’angle recherché s’obtient en additionnant les mesures individuelles (la méthode est semblable à celle décrite dans la section sur les azimuts ci-dessus).
1 1 Comment mesurer la taille d’une cible (hauteur et largeur) à l’aide des mesures d’azimut (tous modèles) En vertu de la formule de mesure de distance, la hauteur se calcule comme suit : H = D x w . Pour mesurer la taille, estimer d’abord la distance jusqu’à la cible, puis mesurer l’angle d’azimut ou l’angle en hauteur .
12 GARANTIE À VIE LIMITÉE V otr e pr oduit Bushnell® est garanti exempt de défauts de matériaux et de fabrication pendant la durée de vie de son premier propriétair e.
13 ACERCA DE LA RETÍCULA La escala vertical (retícula) visible a través de la mitad derecha del binocular le permite calcular la distancia hasta un objeto si conoce su altura, o calcular la altura de un objeto si conoce la distancia hasta el mismo.
14 Acerca de la r etícula telemétrica En la retícula hay líneas verticales y horizontales (Fig. 1). Cada división menor en las líneas verticales y horizontales representa 5 milipulgadas y cada división mayor representa 10 milipulgadas.
15 Medición del ángulo superior e inferior: Los ángulos superior e inferior se reeren al ángulo incluido entre dos blancos cualesquiera (o dos extremos de un blanco) contra la línea vertical de la retícula. La medición de un ángulo superior e inferior es similar a la medición del azimut.
16 Cómo se usa la retícula para medir la distancia La medición de la distancia de un blanco se puede calcular usando la retícula de milipulgadas. Consulte el ejemplo de la Fig. 5 anterior . (Nota: el mismo concepto y formula se aplica cuando se usa la retícula vertical de cualquiera de los modelos de binoculares T actical, en la Fig.
17 Cómo se mide el tamaño del blanco (altura y anchura) usando las lecturas del azimut (ambos modelos) De acuerdo con la fórmula para medir la distancia, se puede calcular la altura usando: H = D x w . Cuando se mide el tamaño, primero hay que estimar la distancia hasta el blanco, luego hay que medir el azimut o el ángulo superior e inferior .
18 GARANTÍA LIMIT ADA P ARA TODA LA VIDA Su producto Bushnell® está garantizado contra defectos de material y fabricación durante toda la vida del pr opietario original.
19 INFORMA TION ZUM F ADENKREUZ Mit Hilfe der vertikalen Skala (Fadenkreuz), das durch die rechte Hälfte des Fernglases sichtbar wird, können Sie die Entfernung zu einem Zielobjekt berechnen, wenn sie dessen Höhe kennen, oder die Höhe eines Zielobjekts berechnen, wenn Sie dessen Entfernung von Ihnen kennen.
20 Das Fadenkreuz zur Entfernungsmessung Auf dem Fadenkreuz (Abb. 1) benden sich vertikale und horizontale Linien. Jede kleine Unterteilung sowohl auf den vertikalen als auch auf den horizontalen L.
21 Messung des oberen und unter en Winkels: Oberer und unterer W inkel bezeichnet den W inkel zwischen zwei beliebigen Zielen (oder zwei Enden eines Ziels) an der verti- kalen Linie auf dem Fadenkreuz. Eine Messung des oberen und unteren W inkels wird ähnlich wie eine Messung des Azimut-W inkels durchgeführt.
22 Falls die oberen und / oder unteren Grenzwerte des Ziels größer als der Milli-Inch-W ert auf dem Fadenkreuz sind, kann die Messung schrittweise durchgeführt werden und der W inkel lässt sich durch die Addition der W erte der einzelnen Schritte ermitteln.
23 Messung der Größe eines Ziels (Höhe und Br eite) durch Ablesen der Azimut-Anzeige (beide Modelle) Gemäß der Formel für die Entfernungsmessung können Sie mit Hilfe folgender Formel die Höhe berechnen: H = D x w .
24 BESCHRÄNKTE LEBENSLANGE GARANTIE Sie erhalten für Ihr Bushnell®-Produkt eine lebenslange Garantie. Die Garantie gilt für den Erstbesitzer und erstreckt sich auf Material- und Herstellungsfehler .
25 INFORMAZIONI SUL RETICOLO La scala verticale (reticolo), visibile sulla sezione destra del binocolo, permette di calcolare la distanza ad un oggetto del quale si conosce l’altezza, o di calcolare l’altezza di un oggetto se si conosce la distanza ad esso.
26 Informazioni sul reticolo di rilevamento Il reticolo contiene linee verticali e orizzontali (Fig. 1). Ogni divisione più piccola sulle linee verticali e orizzontali rappresenta 5 mil (millesimo di radiante), ed ogni divisione più grande rappresenta 10 mil.
27 Misura dell’angolo superiore e inferior e: L ’angolo superiore e inferiore è l’angolo compreso fra due bersagli (o due estremità di un bersaglio) rispetto alla linea verticale sul reticolo. La misurazione di un angolo superiore e inferiore è simile alla misurazione dell’azimut.
28 Come usare il r eticolo per misurare la distanza La distanza di un bersaglio può essere calcolata usando il reticolo mil. Fare riferimento all’esempio della Fig. 5. (Nota: lo stesso principio e la stessa formula si applicano quando viene usato il reticolo verticale di ogni modello di binocolo T actical; la Fig.
29 Come misurare la dimensione di un bersaglio (altezza e larghezza) usando i valori dell’azimut (per entrambi i modelli) Applicando la formula per il calcolo della distanza, è possibile calcolare l’altezza usando: H = D x w .
30 GARANZIA LIMIT A T A A VIT A Si garantisce che questo pr odotto Bushnell® sarà esente da difetti di materiale e fabbricazione finché rimarrà in possesso del proprietario originale.
31 INFORMAÇÕES SOBRE O RETÍCULO A escala vertical (retículo) visível pela metade direita do binóculo permite calcular a distância a um objeto de altura é conhecida, ou calcular a altura do objeto quando se conhece sua distância. Instruções detalhadas para o uso do retículo são fornecidas nas próximas páginas deste manual.
32 Informações sobre r etículo com telêmetro O retículo apresenta linhas verticais e horizontais (Fig. 1). As divisões menores, em ambas as linhas, representam 5 mil e as divisões maiores representam 10 mil.
33 Medida do ângulo superior e inferior: Ângulo superior e inferior é o ângulo entre dois alvos quaisquer (ou duas extremidades de um mesmo alvo) contra a linha verti - cal no retículo. A medida do ângulo superior e inferior é similar a do azimute.
34 Quando o limite superior e/ou inferior do alvo ultrapassar os mil do retículo, ele poderá ser medido em etapas e o ângulo é obtido somando-se o valor de cada etapa. (O processo será similar àquele previamente descrito na seção de medidas lin- eares).
35 Como medir o tamanho do alvo (altura e largura) usando as leituras de azimutes (para ambos os modelos) De acordo com a fórmula para medir distâncias, pode-se calcular a altura da seguinte forma: H = D x w . Ao medir o tamanho, primeiro estime a distância ao alvo e então meça o azimute ou o ângulo superior e inferior .
