You didn't leave it on long enough. It flashes once every ~10 seconds. It can be used as a locator or as a signal to others (aka beacon)I was testing it out, and it just gave out four bright flashes and one bright flash with declining brightness. Anyone know what it's used for?
To me, alot of these modes are pretty much useless. I like having the option of a strobe, and maybe one more blinking mode. Beacon, and SOS is pointless to me.
Beacon is great if you're on a 'big lake' or waterway and after fishing (it's always dark) you start home and need to find camp. Where I fish in the north there are no other cottages or such to use as landmarks.
Beats a strobe in my opinion.
