Quick take

Eco-friendly foam strike indicators that are 30% lighter and suspend 25% more weight than plastic, landing softly and detecting subtle takes.

This three-pack of foam strike indicators from Airflo comes in assorted colors in a half-inch size. The foam body is lighter than the plastic style it replaces and is meant to break down over time if one is lost on the water. The leader slips through a cap that tightens with a nut, so rigging takes seconds. It suits fly anglers who want a float that lands softly and stays easy to see.

Best for

Nymph fishing where sensitive strike detection matters
Fly anglers who prefer lightweight indicators for delicate presentations
