Thank you for your inquiry and question about this product. Yes, the Mares Diamond Line (2mm) is an excellent choice for a spearfishing wishbone. In fact, Mares explicitly designs this specific 2mm line to be used for "ogives" (wishbones) and heavy-duty reel lines. It works great for a wishbone due to several key factors:
Why It Works Well - High Tensile Strength: Because it has a 100% Dyneema core, the 2mm version boasts a massive tensile strength of around 300 kg (660 lbs). It can easily handle the load of heavily tensioned power bands. Polyester Protective Jacket: Pure Dyneema is incredibly strong but can be slippery and prone to friction wear. The Mares Diamond Line features a woven HT (High Tensile) Polyester outer jacket. This coating protects the inner Dyneema core from getting quickly frayed or cut by the sharp notches or shark fins on your spear shaft.
Excellent Knot Retention: Pure Dyneema can occasionally slip out of sheet bends or constriction knots under extreme pressure. The textured polyester cover on this line bites into itself tightly, ensuring your constrictor knots and terminal loops stay locked in the rubber.
A Quick Tip for Use: While 2mm is incredibly strong, it is on the slightly thicker side for a wishbone. Pros: It will last a very long time and resist fraying much better than thinner 1.5mm lines.
Cons: It might be a tight fit if you are trying to thread it into very small ID (Inner Diameter) rubber bands, and it creates slightly more drag (though negligible for most setups).
Pro-Tip: When melting the ends of the line after tying your wishbone knots, make sure to burn them into a clean, solid "mushroom" dome. Because it has a dual-layer construction (Polyester over Dyneema), fusing the layers cleanly prevents the jacket from sliding off the core under tension.
