Hi There
I want to buy a canister diving flashlight,budget about $200-300. I just wonder is there any requirements about the size of canister ?
And any one knows the "Whats the angle of main beam and additional beam" Is it "b" is the main beam and "a" is the additonal beam ?(see below photo)
I am not a senior diver, But i don't know what the angle of main beam is the matters ? Some one said the beam angle more focus the more lumen will be lose .
In what kind of degree of beam angle do you guys think is the best ? many thinks
