Hi, I'm a new recreational diver with a couple of questions related to beam angle. I'm looking to buy my first light or two. They'll be used for dark areas on daylight dives and possibly some night dives, in New England as well as some warmer/clearer parts of the world. No video or photography, just want to see what's down there.
- In New England water I know backscatter becomes an issue. But what beam angles work well in silty water? I'm sure 60*+ becomes a mess, but what about 30-40*? 15-20*? Is it necessary or advisable to go all the way down to 8*?
- Do the focusable lights like the ones from Bigblue and Tovatec work well?
- Do you consider beam angle when picking primary vs. backup? I.e, a wider light for primary and a narrower one for secondary?
- Should I even worry about this, or just buy a decent looking light?
