Surprised its a nice sturdy fin for such a low cost. I'm using it in a thruster setup with my board. Should give me the stability I need charging the big waves this winter. ### ⭐⭐⭐⭐⭐ Good buying *by H***Y on July 25, 2025* Works great, easy to install and durable ### ⭐⭐⭐⭐⭐ Fits ISLE Pioneer 2 & 3 Inflatable SUP *by B***A on November 25, 2025* Accidentally lost my iSUP fin on a paddle and reeeeeeally didn't want to spend $40 and an extra $20 for shipping on the branded fin. I was delighted to find this, it's a super simple swap for my ISLE Pioneer 2 Inflatable Paddle Board and pretty affordable. I actually ended up buying a few different sizes from this company to tailor to different paddling environments. I bought one for the deeper lakes for more stability and one for shallower lakes/ponds. ## Frequently Bought Together - Santa Barbara Surfing SBS - 8 inch Longboard & SUP Single Fin - 8" Center Fin for Surfboard & Paddleboard - Santa Barbara Surfing SBS - No Tool Stainless Steel Fin Screw for Longboard and SUP - Choose 2 or 3 Pack - SBS 10" Surf & SUP Fin - Free No Tool Fin Screw - 10 inch Center Fin for Longboard, Surfboard & Paddleboard --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/19078055-sbs-8-inch-longboard-and-sup-single-fin-8-center](https://www.desertcart.tn/products/19078055-sbs-8-inch-longboard-and-sup-single-fin-8-center) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-30*
