Opening the door of possibilities, the Channel Islands Tech 1 Fins allow you to draw bold new lines you have yet to explore. Allowing for ultimate control, CI fins offer a predictable and consistent feel underfoot while fulfilling the high demand for the drive and release needed at a professional of level surfing. Al Merrick has refined his designs to meet the needs of surfers today but has remained true to the original layout he developed in the 80's. The Tech 1 fins offer a wide base, long rake and his signature smaller center fin that frees up the tail for a more rippable approach. Using proven templates, modern technology and Channel Islands quality, the Tech 1 Fin series has the performance you want and all the versatility you need to do big things in the water. Tech 1 is designed to perform in a variety of conditions and has a wide base for drive off of the bottom, more rake for big carves, and a finer tip for release off of the top. The Tech 1 honeycomb hexagonal core combined with the Al Merrick template offers a medium flex pattern, making this fin a versatile option for a wide range of surfing abilities. Designed with riders 165lbs and over in mind.

    Channel Islands Tech 1 Large 1 Tab Fins Great finsReview by Nektonic Nektonic
    I've tried several different sets of tri fins over the years (performers, JF, occy, EA, F6, accelerators, h3 nexus, HS1, chilli.....just to name a few) and these are the best fins by far. Great drive through turns, and while they provide good hold they also release when you want them to.

    Channel Islands Tech 1 Large 1 Tab Fins Best finsReview by Joe Joe Joe Joe
    Great fins for control in any type of wave. Fast, and most important they hold. This fin is what most pros on the WSL use. A must for a surfer that doesnt have a whole lotta cash for several fins.
