How we calculate scores →About this gear
A legacy personal rescue strobe with a large sliding switch, lashing loops and a base that lets it stand upright. The Waterbug version adds water activation to manual operation.
Consider before buying
Mounting matters: Practical Boat Owner found that a lifejacket and the wearer could obscure part of the flash. Its short strobe pulse was also harder to spot than the longer flashes from newer LEDs.
Our take
Useful to understand if you already own one, but for a new surface signalling kit we would compare current LED rescue lights first. A visible light helps nearby rescuers find you; it does not send a distress message.
