They usually contain 2 x red handheld flares and 2 x orange handheld smokes. Coastal packs are for up to 7 miles and add 2 x red parachute flares. Offshore packs are for over 7 miles, they boost the contents to 4 x parachute flares, 4 x red handhelds and 2 orange handheld smokes. I would also recommend adding extra parachute flares if you regularly travel further away from help. It’s best practice to keep this container in a dedicated flares locker so it can easily be found and removed.
