## **Differences Between S3, S5, and S7 Models**
The **Sonar Titan** series comes in three different sink rates: **S3, S5, and S7**. The number indicates the **sink rate in inches per second (IPS)**, which determines how quickly your fly reaches the desired depth.
### **1. Sonar Titan S3 (Slow Sink – 3 IPS)**
– **Best for:** Shallow water fishing, trout, and bass in moderate currents.
– **Ideal Use:** Nymphing, streamers in slow-moving water, or when a subtle sink is needed.
– **Why Choose S3?** If you need a controlled descent without your fly dropping too fast, the S3 is perfect for delicate presentations.
### **2. Sonar Titan S5 (Medium Sink – 5 IPS)**
– **Best for:** Versatile fishing in varying depths, including rivers and lakes.
– **Ideal Use:** Streamer fishing, deeper nymphing, and moderate currents.
– **Why Choose S5?** The balanced sink rate makes it a great all-around choice for most freshwater and light saltwater applications.
### **3. Sonar Titan S7 (Fast Sink – 7 IPS)**
– **Best for:** Deep water, strong currents, and saltwater species.
– **Ideal Use:** Striper, pike, musky, and deep lake trout fishing.
– **Why Choose S7?** When you need to get your fly down quickly in fast-moving water or deep pools, the S7 ensures your presentation stays in the strike zone.

## **Choosing the Right Size & Weight**
Fly lines are rated by **weight (WF – Weight Forward)**, which should match your rod’s weight rating. The **Sonar Titan** is available in sizes **#3 through #12**, making it suitable for a wide range of fishing scenarios:
– **#3-#5:** Ideal for small streams, trout, and panfish.
– **#6-#8:** Great for bass, larger trout, and light saltwater species.
– **#9-#12:** Designed for big game fish like pike, musky, and saltwater predators.
### **Pro Tip:**
– If fishing in **heavy wind or deep water**, consider going **one line weight heavier** for better turnover.
– For **delicate presentations**, stick to the recommended weight for your rod.
