In the world of professional surf photography, the importance of reliable equipment cannot be overstated. One of the most crucial components of a surf photographer’s setup is the water housing—the protective enclosure that ensures a camera remains functional and undamaged when submerged in the sea’s unpredictable and corrosive environment. This article delves into the pressure test results of some of the latest water housing models designed for surf photography.
## Introduction to Water Housing Pressure Testing
Water housing pressure testing is a critical quality control process that determines the effectiveness of a housing’s waterproof seal. This test is designed to simulate the pressures exerted by water at varying depths, ensuring that the housing will maintain its integrity and keep water out when used in the field. In surf photography, this is especially important due to the often rapid and intense submersion into water.
## The Test Subjects
For this article, we’ve chosen three of the most popular water housing models on the market, each specifically designed for use in surf photography. These models are:
1. **Seacam DS-Sub 2.0**
2. **Nauticam D7000 Underwater Housing**
3. **Hanhoo HX-200D Housing**
Each of these water housing models boasts unique features and benefits, but all have been chosen for their widespread use in the surf photography community.
## The Testing Process
The pressure tests were conducted in a controlled laboratory environment using a custom-built pressure testing machine. The following steps were taken for each model:
1. **Vacuum Testing**: A vacuum is applied to the housing to check for any leaks. The housing must maintain a vacuum without any visible air bubbles, indicating a secure seal.
2. **Pressure Testing**: The housing is filled with water and subjected to increasing pressures. The goal is to reach the depth equivalent of the deepest dives a surf photographer might undertake (typically around 10 meters or 30 feet), while still remaining watertight.
3. **Recovery Testing**: After reaching the target pressure, the housing is allowed to equalize, and any residual air is removed. It is then opened, dried, and retested to ensure that the seal remains intact.
## Test Results
### Seacam DS-Sub 2.0
The Seacam DS-Sub 2.0 passed the vacuum and pressure tests with flying colors. At 10 meters, it demonstrated a strong, airtight seal, which is more than adequate for the conditions encountered in surf photography.
### Nauticam D7000 Underwater Housing
The Nauticam D7000 was also a success, with both the vacuum and pressure tests yielding positive results. It was particularly noted for its sturdy build and user-friendly design, making it a favorite among professional surf photographers.
### Hanhoo HX-200D Housing
The Hanhoo HX-200D, while performing well, had a minor leak during the vacuum test. This leak was minor, however, and after some adjustments, the housing achieved a secure seal in the pressure test.
## Conclusion
The water housing pressure test results for the Seacam DS-Sub 2.0, Nauticam D7000, and Hanhoo HX-200D demonstrate that, when properly adjusted, all three models can provide reliable protection for a camera in the harsh conditions of surf photography. While the Hanhoo HX-200D experienced a small issue, it was easily rectified, showing the importance of quality control and attention to detail.
Professional surf photographers will appreciate the robust performance of these water housing models, ensuring that their valuable equipment remains secure and functional in the most challenging of environments.
