Seaguar InvizX Fluorocarbon

A popular freshwater fluorocarbon mainline. Fluoro sinks and is hard to see underwater, which is why bass anglers use it for bottom baits and as a leader. It complements braid rather than replacing it.

What the maker and reviewers highlight

Seaguar says it is its most castable line; Bassmaster rates its castability best of Seaguar's lines [source]
Ranks high for abrasion resistance (Bassmaster) [source]
Less visible underwater than mono or coated lines (maker) [source]

Things to weigh

Fluorocarbon sinks, so it is a poor fit for topwater (Bassmaster) [source]

Who it's for in Texas

Clear-water Texas reservoirs and finesse presentations are where fluoro earns its keep, either as a mainline or as a leader tied to braid.

My take: coming soon

We have not tested this one ourselves yet. If I get it in the field, my notes will go here. No rating is given.
