# **How to Choose a New Boxed Spare Cartridge/Spool for a Hardy Demon 7000 Fly Fishing Reel**
Fly fishing enthusiasts know that having the right gear is essential for a successful day on the water. One of the most critical components of your setup is the fly reel, and the **Hardy Demon 7000** is a favorite among anglers for its durability and smooth performance. However, even the best reels require maintenance and occasional upgrades—especially when it comes to spare spools or cartridges.
Whether you need a backup for different fly lines or a replacement due to wear, choosing the right **boxed spare cartridge/spool** for your Hardy Demon 7000 is crucial. In this guide, we’ll break down the key factors to consider when selecting a new spool to ensure compatibility, performance, and longevity.
## **1. Compatibility: Ensure the Spool Fits Your Hardy Demon 7000**
The first and most important consideration is **compatibility**. Not all spare spools will fit the Hardy Demon 7000, so you must verify that the replacement is specifically designed for this model. Hardy offers **official spare spools** that guarantee a perfect fit, but some third-party manufacturers also produce compatible options.
**Key points to check:**
– **Model number match** – Ensure the spare spool is labeled for the Demon 7000.
– **Spool dimensions** – Incorrect width or arbor size can affect line capacity and drag performance.
– **Drag system compatibility** – The Demon 7000 has a sealed drag system; the spool must align correctly to maintain smooth operation.
## **2. Material & Build Quality**
The Hardy Demon 7000 is known for its **machined aluminum construction**, which provides strength and corrosion resistance. When choosing a spare spool, look for similar high-quality materials to maintain the reel’s performance.
– **Aluminum spools** – Lightweight yet durable, ideal for saltwater and freshwater use.
– **Anodized finish** – Protects against scratches and corrosion, extending the spool’s lifespan.
– **Precision machining** – Ensures smooth rotation and proper alignment with the reel.
Avoid cheap plastic or low-grade metal spools, as they may warp, corrode, or fail under pressure.
## **3. Line Capacity & Arbor Size**
Your spare spool should match the **line weight and backing capacity** of your primary setup. The Hardy Demon 7000 is designed for **7-9 weight lines**, so ensure the spare spool can accommodate the same.
– **Large arbor vs. standard arbor** – Large arbors retrieve line faster and reduce line memory, while standard arbors allow for more backing.
– **Backing capacity** – If you fish for large species (like salmon or steelhead), ensure the spool holds sufficient backing (typically 150-200 yards of 20-30 lb Dacron).
## **4. Purpose: Freshwater vs. Saltwater Use**
If you fish in **saltwater**, corrosion resistance is critical. Look for spools with **marine-grade seals** and **stainless steel components**. For **freshwater anglers**, standard aluminum spools are usually sufficient.
## **5. Brand Considerations: OEM vs. Aftermarket**
– **Hardy OEM (Original Equipment Manufacturer) spools** – Guaranteed fit and performance but may be more expensive.
– **Aftermarket spools** – Often more affordable, but quality varies. Stick to reputable brands like **KyleBooker** for reliable alternatives.
## **6. Price & Warranty**
While budget is a factor, investing in a high-quality spare spool ensures long-term reliability. Check if the spool comes with a **warranty**, especially if purchasing from third-party manufacturers.
## **Final Thoughts**
Choosing the right spare spool for your **Hardy Demon 7000** enhances versatility and ensures you’re prepared for different fishing conditions. Prioritize **compatibility, material quality, and intended use** when making your selection.
