More or less like me, I use them for fishing, but the truth is I do not go fishing that often haha, so it is more like a hobby, where I want the best thrower, another day, the most compact, another day the lightest and more power efficient, etc etc, being all budgets more or less, and if needed I modify them the best I can (which is not much more than trying lenses, leds, and drivers).
I do not get any profit of it, in fact I have given many of them as presents, and told some friends which one would suit them etc.
