I didn't see where I suggested not having any other device. My missed point was when the thread drifted to discussions over how many seconds a SOLAS flare or aerial flare lasts. My personal preference would be to have the option of a signaling device designed to last hours rather than choose when to deploy signaling devices that are ignited and burn at thousands of degrees. Or put even more clearly -- Your list is fine but for another $100 why not have something that lasts for hours and doesn't expire at the rate of flares?
