Features Comparison of Holosun SCS Vs. Holosun 507C
1. Power Source and Battery Life
Holosun SCS
The Holosun SCS stands out with its innovative solar charging system, supplemented by an internal rechargeable battery. This combination not only enhances the sight’s energy efficiency but also offers a potentially indefinite operation time under the right conditions.
The 20,000-hour battery life is a significant advantage, especially with the addition of an intensity override function and a low power indicator.
This feature ensures that shooters are never caught off guard by a dead battery, providing ample warning and the convenience of solar power for prolonged use.
Holosun 507C
The Holosun 507C relies on a dual power source – solar and a CR1632 battery. This sight excels in battery life, boasting up to 50,000 hours of operation, which is impressive for frequent users. The combination of solar power and a long-lasting battery ensures reliability and continuous operation, especially in diverse lighting conditions.
The Solar Failsafe feature adds to its dependability, making sure the sight remains operational even when the battery is low.
Winner
Both sights have impressive power features, but the Holosun SCS edges out slightly due to its solar efficiency and innovative charging system, providing a more seamless experience.
2. Reticle and Optical Quality
Holosun SCS
The SCS model features a 2 MOA dot and 32 MOA circle reticle
The Multi-Reticle System (MRS) allows users to quickly switch between reticle types, catering to different shooting scenarios. Additionally, the multilayer reflective glass ensures maximum light transmission, wear resistance, and reduced glare, contributing to the reticle’s clarity and intensity.
Holosun 507C
The 507C model offers a 2 MOA dot and 32 MOA circle in red, utilizing Holosun’s Red Super LED technology. The red reticle is known for its visibility in a wide range of lighting conditions.
The optical quality is enhanced by multi-coatings on the lenses, providing clear and bright images. The flexibility in reticle choice and the efficient light usage make it a versatile option for various lighting conditions.
Winner
The SCS’s reticle provides a unique visibility advantage, but the 507C’s Red Super LED and multi-coatings offer greater versatility in different lighting conditions, making it the winner in this category.
3. Housing Material and Durability
Holosun SCS
The Holosun SCS is constructed with a titanium housing, which is known for its exceptional strength-to-weight ratio. This choice of material ensures that the sight is not only lightweight but also extremely durable.
Titanium is resistant to corrosion and can withstand rough handling, making the SCS a reliable option for shooters who frequent various environments, from humid forests to sandy terrains.
The robustness of this material contributes to the overall longevity of the sight, ensuring it can endure the rigors of regular use without compromising its performance or integrity.
Holosun 507C
The 507C model features a housing made of 7075 T6 Aluminum, a material well-regarded for its high strength and used extensively in aerospace applications. This aluminum alloy provides excellent durability and resistance to wear and tear.
The anodized surface finish adds an extra layer of protection against the elements, enhancing its resilience in different shooting conditions. This durability makes the 507C a solid choice for shooters who need a reliable, long-lasting sight.
Winner
Both models offer impressive durability, but the titanium housing of the Holosun SCS provides a slight edge in terms of strength and corrosion resistance, making it the winner in this category.
