The Loon Outdoors BioStrike gives fly anglers a clean, adjustable way to track takes when nymphing for trout, steelhead, and other river fish that demand precise depth control and natural drifts. This putty strike indicator lets you roll the material into the size you need and place it on the leader at the exact depth your rig calls for, with the amount depending on the weight of your flies and the water you are fishing. Its biodegradable formula adds an environmentally friendly option to your fly vest, and the reusable putty stores easily in the container after a day on the water so you can use it again on the next trip. With 1 oz. of material, BioStrike gives anglers a practical strike detection tool that adapts quickly as current speed, fly weight, and presentation depth change.

• Biodegradable putty strike indicator for fly fishing applications
• Roll it to the size needed for your flies and target depth
• Reusable formula stores back in the container after fishing
• 1 oz. container for repeated on-the-water adjustments
