Recently, we got D28 3600 feedbacks from the professional diver @tom.st.george, after his testing this dive light at Tulum Mexico for several months. “I really like this D28 dive light. The beam is really good and powerful. I make a very good handheld primary (instead of the traditional cannister). It can even be used as a sort of backup primary light too, as it fits in a pocket or pouch. And I think this D28 would be popular with tech and cave divers if there was an option for a hard Goodman handle.”
