Check out the GearTrac from YakAttack. It’s a track system manufactured from high quality 6000 series aluminium (alloyed with magnesium and silicon). It has an anodised finish which will no doubt give the product a very long working life whether it be in fresh or saltwater.
I took delivery of some today and I’ll be installing and reviewing this item soon. It allows multiple rigging options, too many in fact!, I’ll be spending quite some hours this weekend deciding how best to utilise this new product. Watch this space.
