When the fish are line shy-- Opsin helps me get bit more often.

It's a great line for the price. I thought the connecting spools was going to be a dumb hack, but 3 hours into a boat trip I was showing it to all my friends.

I am really impressed with Opsin 50lb flouro. I rigged up 4 of my 5 rods with the 50lb flouro and landed 3 nice blue fin from 50 to 75 pounds last week. I went yellowtail fishing yesterday and left all the 50lb Opsin leaders on. I had limits by noon! Other anglers were using 35lb flouro and losing larger fish. I had no problem getting bit with the 50lb Opsin and ended up handing off 4 fish after I had limits.

“This has never happened to me but it seemed like every cast equaled a hook up. Love this line. I passed off my rod several times when others couldn’t buy a bite. Opsin for the win!!”

After months of development, we are thrilled to release our 6 lb surf and freshwater line. We believe we found the right balance of creating a supple line for smooth casting and providing you with enough abrasion resistance to hold up to surf, sand, and jetty rocks. We can't wait to hear about your next pb while using Opsin Fluorocarbon.

There's a reason this 10lb line is being released 18 months after our launch -- good things take time. We believe we found the right balance in creating a supple line for smooth casting and providing the angler with enough abrasion resistance to pull your next pb fish out of structure and vegetation.

Many times on a fishing trip an angler doesn't know if they are going to limit out on some 15 pound yellowtail or roll up to a school of 60 pound bluefin. Great problems to have! But having a range of fluorocarbon line gives you some piece of mind.
All of our spools interlock for your organizational pleasure.
