The lightweight, Pains Wessex Compact Distress Signals pack contains:
3 red aerial flare cartridges and a penjector firing mechanism.
All enclosed in a tough, water-resistant case.
The penjector is fitted with a stainless-steel spring and striker pin.
It features a slot for easy loading and unloading of the flare cartridges.
Cartridges are stored inside the casing on an elastic lanyard, to avoid them being lost when the base cap is unscrewed.
