Familiarity: I've put it through the wringer
i picked this up because i also have the spot and have really liked it and you can always use a spare. the storms upgrade in waterproofing is necessary for me, but i tend to waterproof with everything. they seem to last longer. anyway, the super bright setting on this is great for fine motor stuff and the lighter setting is perfect for moving with speed and lets you see pretty far out. i use it primarily for night skiing… oh, and battery life is true. lasts forever!
