JerryC Pro Enhanced Focusing Defender - Lens & Device Protector

The JerryC Pro Defender provides rugged force-on-force protection and impact resistance to the JerryC Pro line of clip-on thermal imagers. This protector is the ONLY product on the market that includes provisions for the unique focusable front lens of the JerryC Pro. With an enlarged textured focusing wheel, this defender not only protects the JerryC Pro from multiple impacts but also makes the focusing experience easier, even in austere environments or with gloved hands. 

Rather than using the commonly used Nylon-12 material that shatters upon impact or becomes brittle in cold weather, the main body of the JerryC Pro Defender is made using a proprietary blend of flexible TPU that is multi-impact-rated and offers an ultra-stealthy signature-reducing finish.

This protector is part of our second generation of thermal defenders that improve on the first generation by introducing a custom TPU o-ring to retain the sacrificial lens layers versus the older tab-based system, allowing for easier changes of the lenses for user replacement. 

Key Features:

• Precision screw on fit - Via 2 included replacement screws on the top of the defender and an indexing screw on the bottom, the JerryC Pro fits securely without any risk of falling off
• Enhanced Focus Ring - This Nylon-12 focus ring firmly attaches to the objective lens of the COTI and allows the user a full range of fine focus that's easier to use than the stock knurling.
• TPU O-ring sacrificial lens retention - Using in-house-made O-rings, the sac lenses of our 2nd Generation defenders do away with the older tabbed design for greater strength, and ease of replacement. 
  

Recognizing that each user's requirements are unique, three different protection levels are available that include the following components:

• Optical-grade multi-coated Germanium Sacrificial lens optimized for 8-14µm wavelength, is tested to absorb up to a 0.2g BB at 350fps and UTM and Simunitions at point-blank range with no penetration. Not multi-impact-rated.
• Multi-Impact Rated custom-manufactured Titanium Honeycomb.

Level 1 - Germanium sacrificial lens only. This option provides impact protection with the highest levels of performance. Ideal for users who want maximum performance and thermal signal while still protecting the host lens. No perceived signal loss. Not ideal for situations where multi-hit capabilities are required.

Level 2 - Titanium honeycomb only. A custom-fabricated titanium honeycomb offers multi-hit resistance and has been tested for 400fps with 0.2g BBs at point-blank range. The mesh density is specially sized to be less than 6mm in diameter and to completely stop all 6mm projectiles fired at 400fps. Depending on the frangibility of ammo relative to the ruggedness of the titanium, spalling of projectiles is possible. 

Level 3 - Germanium lens + titanium honeycomb. The ultimate in protection. Both materials are used in tandem for maximum protection and safeguards against spalling. While this combination is multi-impact rated, due to the fragile nature of germanium and spalling, the durability of the germanium is not guaranteed.

Weight: 12g in the Level 2 configuration; 27g in the Level 3 configuration

Replacement germanium sacrificial lenses can be purchased HERE. Proudly designed, made, and assembled in Canada. 

DISCLAIMER: Due to the brittle nature of germanium, Cold Harbour Supply is not liable for damage to the host device as a result of the failure of the user to replace the sacrificial lens as necessary after impacts, when the structural integrity may be compromised.

While similar, this protector will NOT fit the RENV-C, that product can be found here.
