Frequently asked questions

Will the hi-vis color spook fish?

No — pair it with a fluorocarbon leader for an invisible presentation while keeping visual control of your mainline.

Does it really glow under light?

Yes. The chartreuse line reacts vividly under blacklight or fluorescent light, making it perfect for night and low-light fishing.

Spinning or casting?

Both — low memory and visibility make it a great fit for either platform, especially when you need to see every movement.

Keep the hi-vis main for your eyes, add invisible fluoro at the lure for theirs.
