I was really impressed with how well the Problue AC-31-5A Jon Line & Buddy Rope performed during my recent diving trip. The wrist strap is very comfortable and the rope is durable. However, I wish it came with a carrying pouch for convenience.

What is the weight difference between this and the similar product from another brand? Is it true that this option from Problue is lighter and easier to handle? Want to know before making a purchase…?
Junhao Lo –
Thank you for your review, Timothy. We’re happy to provide information on the weight difference between our Problue AC-31-5A Jon Line & Buddy Rope and similar products from other brands. Our Problue AC-31-5A Jon Line & Buddy Rope typically weighs 180 grams. For comparison, a similar product from another brand weighs approximately 220 grams. This 40-gram difference may contribute to our rope being lighter and easier to handle. However, please note that the actual weight may vary depending on several factors, including the specific product model and any potential bundles or accessories. If you have any further questions or concerns, please feel free to ask.
