Appena le persone hanno iniziato a muoversi sull&#8217;acqua e sono comparse le prime imbarcazioni, \u00e8 servito un modo per misurarla ed evitare di incagliarsi.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Oggi questo compito spetta all&#8217;ecoscandaglio. Mostra la profondit\u00e0 sotto la barca e la forma del fondale, e questo ti aiuta a:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>trovare i punti dove sta il pesce foraggio, e quindi dove caccia il predatore;<\/li>\n\n\n\n<li>attraversare in sicurezza i tratti difficili di un fiume;<\/li>\n\n\n\n<li>evitare danni a motore, elica o scafo;<\/li>\n\n\n\n<li>sentirti pi\u00f9 sicuro in uno specchio d&#8217;acqua che non conosci.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Se vai a pescare in un posto nuovo dove non sei mai stato, senza ecoscandaglio \u00e8 quasi impossibile. Certo, puoi orientarti \u00aballa vecchia maniera\u00bb, guardando la riva o le increspature dell&#8217;acqua, ma non avrai la precisione e l&#8217;affidabilit\u00e0 necessarie.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Come funziona un ecoscandaglio e perch\u00e9 mostra i pesci<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Allora, come funziona un ecoscandaglio e perch\u00e9 vediamo i pesci sullo schermo? Il principio \u00e8 semplice.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ogni ecoscandaglio ha un sensore, chiamato trasduttore. Di solito \u00e8 piccolo, anche se di recente sono arrivati modelli pi\u00f9 grandi, come i trasduttori per l&#8217;imaging strutturale. In genere si monta a poppa.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Funziona con le onde sonore. Il trasduttore emette un segnale che rimbalza sul fondo o sugli oggetti nella colonna d&#8217;acqua e torna indietro. I dati arrivano all&#8217;\u00abunit\u00e0 principale\u00bb dell&#8217;ecoscandaglio, che li elabora e li trasforma in un&#8217;immagine sullo schermo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Come viene mostrato tutto questo? Con il Broadband (non con le moderne tecnologie di imaging strutturale, che disegnano rilievi e oggetti nel dettaglio), il fondo appare di solito come una linea. La profondit\u00e0 della linea cambia in base al fondale sotto la barca.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I pesci possono comparire sullo schermo in modi diversi:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>come archi: il metodo vecchio, tipico dei primi ecoscandagli;<\/li>\n\n\n\n<li>come punti o piccole sagome a forma di pesce, come nei modelli moderni.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A volte l&#8217;immagine permette persino di intuire la specie.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pi\u00f9 tempo passi in acqua con l&#8217;ecoscandaglio e pi\u00f9 osservi lo schermo con attenzione, pi\u00f9 diventa facile capire che pesce c&#8217;\u00e8 sotto la barca: predatore o pesce foraggio. Per i pescatori esperti diventa quasi istintivo.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Cos&#8217;\u00e8 il sonar live<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Il sonar live (Live Sonar) mostra in tempo reale e in alta risoluzione i movimenti dei pesci, con molti pi\u00f9 dettagli. Il sistema invia impulsi sonori in acqua e mostra all&#8217;istante i pesci e gli oggetti che li riflettono.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ogni produttore lo chiama in modo diverso:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Lowrance: ActiveTarget<\/li>\n\n\n\n<li>Garmin: Panoptix<\/li>\n\n\n\n<li>Humminbird: Mega Live<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n<\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>Conoscere la profondit\u00e0 \u00e8 sempre stato importante.
