Sudhir Goh –
Will the Problue AC-40 Dive Reel w/Stop Locking System work with a 3mm rope?
Junhao Lo –
Dear Sudhir, thank you for your question about the Problue AC-40 Dive Reel w/Stop Locking System. The reel is designed to work with ropes of varying diameters. However, a 3mm rope is quite thin, and we recommend using a rope with a minimum diameter of 5mm for optimal performance. If you plan to use the reel with a 3mm rope, it’s essential to check the rope’s tensile strength to ensure it can withstand the stresses of diving. If you have any further questions or concerns, please don’t hesitate to ask. Best regards.

Emily Low –
I’ve been using this dive reel for several months now, and I can confidently say it’s one of the best I’ve owned. The stop locking system is so much easier to use than the older models. The build quality is top-notch and it’s performed flawlessly every time. Can’t fault it. Definitely recommend it to any serious scuba diver. One thing it doesn’t have is a wrist attachment for a compass. Would be very inconvenient to have to look at the watch for compass bearings.
Charisa Law –
Does this dive reel come with a wrist attachment for a compass? How about the built-in depth gauge. I need these features for my dives.
Imran Hanafiah –
Hello Charisa, thank you for your interest in our Problue AC-40 Dive Reel. Unfortunately, our dive reel does not come with a wrist attachment for a compass. However, the Problue AC-40 Dive Reel is a popular choice among dive enthusiasts and includes a built-in stop lock mechanism that prevents unintended line pay-outs, keeping your dive line organized throughout the dive. If you’re interested in a dive reel with these additional features, we recommend taking a look at some of the other models offered by Problue. Do you have any other questions or would you like more information on our products?
