It looks like you’re referring to the Osaka Fishing Equipment (OGK) One-Touch Mountain Stream Damo 9.8 inches (25 cm), a telescopic fishing rod designed for mountain stream fishing.
Key Features:
- Length: 9.8 inches (25 cm) when collapsed, extends to a longer length (likely around 2-3 meters when fully extended).
- One-Touch System: Quick and easy telescopic extension for convenience.
- Designed for Mountain Streams: Lightweight and sensitive, ideal for small-stream fishing (e.g., trout, char, or small game fish).
- Portable: Ultra-compact when folded, making it great for backpacking or hiking trips.
- Durable Construction: Typically made with carbon or fiberglass for flexibility and strength.
Common Uses:
- Tenkara-style fishing (Japanese fixed-line fishing).
- Backcountry fishing where space is limited.
- Ultralight fishing in small rivers and streams.
Would you like details on:
- Exact extended length?
- Recommended line weight/lure size?
