Roxanne Koh –
What is the recommended anchoring point for this diving flag during strong currents?
Imran Hanafiah –
Thank you for sharing your concern about the anchoring point of our Problue AC-37-4 Diving Flag. We recommend anchoring the flag to a secure point, such as a weighted anchor or a sturdy rock, to prevent it from drifting away in strong currents. It’s essential to ensure a secure connection to prevent damage to the flag or surrounding marine life. For added stability, consider using a secondary anchor to prevent the flag from tipping over. If you have any further questions or concerns, please don’t hesitate to contact us. We’d be happy to help you use your diving flag safely and effectively.

This diving flag is well-made, but the weak spot is the thin cord for hanging. Should be thicker for added strength.

Would this diving flag be suitable for night diving or is it only for use during the day?
Junhao Lo –
Thank you for sharing your question about our Problue AC-37-4 Diving Flag. This diving flag is designed for use in a variety of conditions, including night diving. The flag is made with reflective materials that will help increase visibility in low-light conditions. However, it’s also recommended to ensure your flag is easily visible to passing boats and other divers. You may also want to consider using additional safety measures, such as a strobe light, to enhance visibility during night diving. If you have any further questions or concerns, please don’t hesitate to reach out.
