Using dive lights for spearfishing, does the beam angle have different effect on spearfishing? I know the wide beam can let me see more of immediate area, while the narrow beam light can focus on specific areas intensively. Should I choose wide or narrow beam? Besides, water visibility is also taken into consideration. If I hunt fishes in muddy water or clear water, are there different demands for dive lights’ beam? I hope my torch can be used in both muddy water and clear water. LOL. Thanks for your help!
