What's the difference between a 20-60X60 vs 20-60X80 spotting scope?

The primary difference between a 20-60x60 and a 20-60x80 spotting scope lies in the size of the objective lens, which impacts various aspects of performance. Here's a breakdown:

1. Objective Lens Diameter:

   • 20-60x60: This scope has a 60mm objective lens.
   • 20-60x80: This scope has an 80mm objective lens.

2. Light Gathering Ability:

   • 20-60x60: Smaller objective lens gathers less light, making it less effective in low-light conditions.
   • 20-60x80: Larger objective lens gathers more light, providing brighter images, especially in dim lighting.

3. Image Brightness and Quality:

   • 20-60x60: Images may be less bright and have slightly lower quality compared to the 80mm version.
   • 20-60x80: Generally produces brighter and sharper images due to better light collection.

4. Field of View:

   • 20-60x60: May have a narrower field of view.
   • 20-60x80: Typically offers a wider field of view, allowing more of the scene to be observed.

6. Price:

   • 20-60x60: Usually more affordable.
   • 20-60x80: Tends to be more expensive due to the larger lens and better performance.

7. Best Use Cases:

   • 20-60x60: Suitable for general use, where portability and cost are more critical.
   • 20-60x80: Ideal for situations requiring high performance in low light, such as dusk or dawn, and for users who prioritize image quality over portability.

In summary, the 20-60x80 spotting scope offers superior performance in terms of brightness, image quality, and field of view, but at the cost of increased size, weight, and price compared to the 20-60x60 model.
