Marine Dye Marker

Of course I hope to never experience the need for a practical application, which does not allow a statement on the quality. The box is nice and small and handy. The advantage over an orange smoke signal Probably lasts forever, does not have to be replaced every 3 years (with the now difficult to solve problem of shipping and proper disposal of pyrotechnics), should be visible much longer after use, since it is fluorescent, possibly even at night with a searchlight, but probably only from the air. In my opinion, the price is inappropriate for a bit of chemistry in a plastic can (like unfortunately many things for the hobby marine sector)

looks like a good product in a good package

not clear the weight and any expiring date. this may cause problems if requested by sailing regulation.
