COME USARE IL RETICOLO
La scala verticale (reticolo) visibile attraverso la metà sinistra del binocolo, al di sopra del display della
bussola, permette di calcolare la distanza di un oggetto conoscendone l’altezza, o l’altezza conoscendone la
distanza. Ogni tacca sulla scala verticale corrisponde a 5 Mil (1 Mil equivale ad un angolo che determina un
oggetto di un metro di altezza ad una distanza di 1000 metri). Perciò, se una carta nautica fornisce l’altezza
di un oggetto, contando il numero di MIL si può determinare la distanza dell’oggetto stesso. DI seguito sono
riportate le due formule (notare l’uso di unità metriche):
1) Per misurare la distanza quando si conosce l’altezza:

Reticolo per la
valutazione della
distanza
Esempio:
Si conosce l’altezza di un faro, pari a 26 m. Sul reticolo,
la sommità del faro corrisponde alla tacca delle 60 mil.
Pertanto si ha 26/60=0,43, che moltiplicato per 1000 ci
da una distanza di 433,3 metri dal faro.
