# **How to Choose the RIO Premier FATHOM Sinking Fly Lines – RIO Official Dealer**
As an angler, selecting the right sinking fly line is crucial for achieving depth, control, and precision in your presentations. The **RIO Premier FATHOM Sinking Fly Lines** are engineered for performance, offering superior sink rates and casting efficiency. Whether you’re targeting deep-water trout, bass, or saltwater species, understanding how to choose the best FATHOM line for your needs will enhance your success on the water.
## **Why Choose RIO Premier FATHOM Sinking Fly Lines?**
RIO is a trusted name in fly fishing, known for innovation and quality. The **Premier FATHOM series** is designed with advanced **AST (Advanced Shooting Technology) coating**, ensuring smooth, long-distance casts even with weighted flies. These lines feature **high-density tungsten sinking cores**, allowing for faster sink rates and better depth control.
Key benefits include:
– **Multiple sink rates** (from **Intermediate to Extra Fast Sink**) for versatile fishing conditions.
– **Durable, abrasion-resistant coating** for longevity in freshwater and saltwater.
– **Low-stretch core** for improved sensitivity and hook-setting power.
– **Optimized taper design** for effortless turnover of large flies.
## **How to Select the Right FATHOM Sinking Line**
### **1. Determine Your Target Depth & Sink Rate**
The FATHOM series offers **six different sink rates**, measured in inches per second (IPS):
– **Intermediate (1.5 IPS)** – Ideal for shallow water or slow-sinking presentations.
– **Slow Sink (2.5 IPS)** – Perfect for mid-depth trout and bass fishing.
– **Medium Sink (3.5 IPS)** – A versatile choice for rivers and lakes.
– **Fast Sink (5.5 IPS)** – Great for deep nymphing and streamer fishing.
– **Extra Fast Sink (6.5 IPS)** – Designed for reaching extreme depths quickly.
– **Ultra-Fast Sink (7.5 IPS)** – Best for saltwater or deep-structure fishing.
**Pro Tip:** Match the sink rate to the water depth and current speed. Faster sink rates are essential in deep or fast-moving water.
### **2. Consider Fly Size & Rod Weight**
– **For lighter flies (trout, panfish)**: A **3-5 weight line** with a **Medium or Slow Sink** rate works best.
– **For streamers and large flies (bass, pike)**: Opt for a **6-8 weight line** with a **Fast or Extra Fast Sink** rate.
– **For saltwater species (stripers, bonefish)**: A **7-9 weight line** with **Ultra-Fast Sink** ensures deep penetration.
### **3. Check the Line Taper & Presentation**
The **FATHOM lines feature a short front taper**, which helps turn over bulky flies efficiently. If you need a more delicate presentation (e.g., for wary trout), consider pairing it with a longer leader.
### **4. Durability & Saltwater Compatibility**
If fishing in saltwater, ensure your line has **corrosion-resistant components**. The FATHOM series is built to withstand harsh conditions, making it a reliable choice for both freshwater and saltwater anglers.
