Because seconds count, the Airflo Depthfinder Big Game fly lines are fast-loading, 30' heads that quickly gets you in the game. And its 300 to 700 grain head drives your fly immediately to depth while the intermediate running line helps keep it there. An extremely low-stretch, 50 lb Power Core means positive hook sets - even at depth.

Guide Recommendations - We highly recommend the Airflo Depthfinder Big Game fly lines any time you need to get down fast (whether that's in deep water or fast current). We love fishing the 500-grain version of this line on one-handed 12-weights, as well as for XXL fly applications such as water-loading the largest Flyducas with 14- to 15-weight custom rods. The 400-grain excels on the vast majority of 10-weights, and the 300-grain casts great on most of today's 8-weights.
