ISDA, International Scuba Diving Academy, opera in tutto il mondo per la formazione di subacquei sportivi e professionisti. Giovane ma già grande, è ad oggi presente non solo in tutta Italia , ma anche in Egitto, alle Maldive, in Sudan, a Malta, a Santo Domingo, in Indonesia ed in Brasile. Ovunque operi, ISDA offre la garanzia di alti standard, sia per la qualità dei propri iter formativi, sia in adeguamento alle norme europee e mondiali ed alle legislazioni locali in materia di sicurezza. Le certificazioni ISDA ha ricevuto le certificazioni di qualità UNITER ed EUF secondo le normative europee EN14153-1/2/3 (ISO 24801-1/2/3) e EN 14413-1/2 (ISO 24802-1/2) ed anche ISO 11107 ed ISO 11121. Queste normative sanciscono e determinano gli standard di massima qualità e sicurezza dei corsi sub ISDA da Scuba Diver ad Istruttore. La qualità dei materiali didattici Da sempre ISDA punta sulla qualità dei materiali didattici. Sono molto apprezzate la completezza dei kit, l'accuratezza editoriale dei manuali, che sono facili da consultare e studiare, corredati di foto e disegni a colori, e la qualità e la ricchezza di informazioni nei testi. I corsi Il programma didattico, estremamente ampio, si pregia, oltre che delle linee ARA, Apnea e Tek, di quattro Corsi Speciali: Archeologia Subacquea, creato in collaborazione con la Soprintendenza del Mare di Palermo; Biologia Marina, che sta riscuotendo un grande successo ed il cui manuale si distingue per la chiarezza e l'approfondimento con cui tratta la materia, nonché per le 80 schede di riconoscimento; Sommozzatore di Protezione Civile, un corso nuovo ed entusiasmante, se pur decisamente impegnativo; Scubamaster, un corso sviluppato in moduli successivi, che accompagnano l’allievo gradualmente nel mondo della subacquea tecnica; Parasub, per aprire a tutti le porte del fantastico mondo subacqueo. I progetti ISDA nasce dall'amore per il mare e questo non vuole dire solo occuparsi di formazione, ma anche adoperarsi perché il mare venga vissuto nel migliore dei modi, con rispetto e sempre rinnovato stupore. E' in quest'ottica che nascono progetti importanti in campo Ecologia e Solidarietà, che coinvolgono tutte le sedi dell'agenzia, in Italia e all'estero. Nell'ambito delle iniziative di GREEN WAVE PROJECT , ISDA ha stretto accordi con diverse Aree Marine Protette (progetto Biology Diver) e ha creato la figura dell’ISDA RANGER per il monitoraggio e la tutela dell'ecosistema marino costiero e per la diffusione di una cultura più attenta e consapevole. Organizza inoltre campagne di pulizia dei fondali e di sensibilizzazione civica al rispetto ambientale (progetto Prendi la Bombola e Spazza).
