#### **Cons**

1. **Cost**

High-quality marine upgrades like the AirMar 33-391-01 can be expensive. The price may be a significant investment, especially for smaller boats or hobbyists on a tight budget. You ll need to weigh the potential benefits against the upfront cost.

2. **Potential Complexity in Installation**

While AirMar products are generally user-friendly, installing a fairing block may require some mechanical skill or the assistance of a professional. If you re not comfortable with boat modifications, you may need to hire a marine technician, adding to the overall cost.

3. **Limited Customization**

5. **Compatibility Issues with Non-Furuno Systems**

Although this block is designed for Furuno s B45 radar, if you re using a different radar or navigation system, you may need additional adapters or modifications to ensure compatibility. This could complicate the installation process.

6. **Weight Considerations**

Adding a fairing block increases the weight of your boat slightly. While the impact is usually minimal, it s something to consider if your boat is already near its weight capacity or if you re concerned about balance and handling.

7. **Market Availability and Lead Times**

Depending on your location, AirMar products may not be readily available at all marine supply stores. You might need to order online, which could result in longer wait times for delivery.
