🔍 Key Concepts

• Pyrotechnic signals and how they differ (parachute, handheld, smoke) • Effectiveness of signals at night vs. daytime • How far each device can be seen by a ship on the horizon

💭 Think About

• Which of these devices is designed to be seen from the greatest distance, not just close by? • Which option is primarily intended for night use, and which are better suited for daylight? • Think about height and duration: which signal gets the highest and lasts long enough for a distant ship to notice?

✅ Before You Answer

• Identify which items are pyrotechnic night signals versus day signals • Consider which option provides the greatest range of visibility to a distant vessel • Verify which device is specifically described in training materials as suitable for long‑range distress signaling at night
