Balin Cyclone Leash
Sizes: 6 | 7 | 9 | 10 | 12 | 15
(7.4Mm & 2 Stainless Swivels)
If you are off to Indo step up to a 7.4mm leash it gives you 10% more strength in the PU cord.
If you want to be doubly sure go for an exra foot on your regular size. You’ll get extra stretch and release on that critical go-down in front of the reef.
