Double envelope signaling buoys // Internal PVC bladder and external nylon envelope.
 Supplied with 17m of orange halyard + a "FOX" flag, available in torpedo or round version.
 The lead pocket is attached to the end of a double envelope buoy.
 When a 2kg lead is housed there, the buoy stands in beacon mode, thus creating better visibility on the water and better safety.
 The beacon position is used to mark a spot or mark a drift.
 To put the buoy back in drag, simply place the lead in the envelope under the buoy.
 This also allows for better stability. Pocket not included.
