Designed for serious spearfishing, Mahi Big Dog Floatlines combine strength, abrasion resistance, and reliability where it matters most. Built with a Dyneema outer sheath and a PP (polypropylene) floating core, these lines are made to handle everything from the reef to big blue.
The Dyneema outer provides excellent cut and abrasion resistance while reducing drag and tangling in the water. Inside, the PP core delivers consistent flotation and a simple, proven construction that’s visible to the boatman on the surface and has a colour that disappears and blends at depth. With a shark clip at one end and a loop at the other, the Bid Dog is set up to handle your butterfish to your bluefin.
Available in 15m, 20m, 25m, and 30m lengths, these floatlines suit everything from inshore reef diving to blue-water missions.
