Lens Coating Types: FMC vs. Non-FMC
The type of lens coating in your binoculars can significantly impact your underwater observation experience, especially when diving in cold water. Two common types of lens coatings are fully multi-coated (FMC) and non-FMC. Understanding the differences between these coatings will help you choose the best binoculars for your aquatic exploration needs.
Fully multi-coated lenses (FMC) provide the highest level of protection against glare and reflection on the water. These lenses have multiple layers of anti-reflective coatings on all air-to-glass surfaces, allowing more light to pass through the binoculars. This enhances visibility and improves image quality, making FMC binoculars ideal for underwater use.
|Reduce glare and reflection on the water
|More susceptible to glare and reflections
|Provide better image quality and enhanced visibility
|May result in poorer image quality and reduced visibility
|Offer superior light transmission
|May cause light loss and decreased brightness
On the other hand, binoculars with non-FMC lenses may be more affordable but are not as effective in reducing glare and reflection. These lenses have a single layer of coating or may not be coated at all, making them more susceptible to light loss and decreased brightness in challenging lighting conditions.
When choosing binoculars for diving in cold water, it is recommended to opt for models with fully multi-coated lenses (FMC). These lenses provide superior protection against glare and reflection, ensuring clear and vibrant underwater observation. They are especially beneficial when dealing with the bright sunlight and reflective surfaces encountered during diving activities.
- Fully Multi-Coated Lenses (FMC): Provide the best protection against glare and reflection on the water, resulting in enhanced image quality and visibility.
- Non-FMC Lenses: More susceptible to glare and reflections, may cause light loss and reduced brightness.
Make sure to consider the lens coating type when selecting binoculars for diving in cold water. FMC lenses offer superior performance in reducing glare and reflection, providing a more enjoyable and productive underwater observation experience.
Focus Mechanism and Rangefinders
Understanding the various focus mechanisms and the benefits of a reticle rangefinder can help you choose the right binoculars for your cold water diving adventures. When it comes to focus mechanisms, there are two main types to consider: center focus and individual focus.
Center focus binoculars have a single knob located in the center that adjusts the focus for both eyepieces simultaneously. This makes them quick and easy to use, especially when you need to adjust the focus quickly. On the other hand, individual focus binoculars have separate focus adjustment rings for each eyepiece. This allows you to fine-tune the focus for each eye separately, which can be beneficial if you have different vision requirements for each eye.
A reticle rangefinder is a feature that can be particularly useful for estimating distances underwater. It consists of a horizontal and vertical scale that is superimposed on the view through the binoculars. By aligning the scales with a known object or using the scale to measure the size of an object, you can estimate its distance. This can be helpful for underwater navigation or assessing the size of marine life.

– Ideal for those with different vision requirements for each eye
Choosing the Right Objective Lens Size
The size of the objective lens in your binoculars can significantly impact the clarity and light-gathering capabilities when diving in cold water. A larger objective lens allows more light to enter, resulting in brighter and clearer images. This is especially important in low-light conditions or when exploring deeper underwater.
However, it’s important to consider the trade-offs associated with larger objective lenses. While they offer superior light-gathering abilities, they also tend to be heavier and bulkier. This can make them more challenging to handle and may impact your overall diving experience. It’s important to find a balance between lens size and practicality.
For diving in cold water, objective lenses between 40mm and 50mm are generally recommended. They offer a good compromise between light-gathering capabilities and portability. These sizes provide sufficient brightness and image clarity without adding excessive weight to your diving gear.
Benefits of Different Objective Lens Sizes:
|Objective Lens Size
|Compact and lightweight without sacrificing brightness
