The Salted Line CH A7IV GEN2 version features several premium upgrades, including:

  • Integrated M33 threaded bulkhead interface
  • A larger LCD screen window enhances visibility.
  • Compatibility with a detachable 2-stage shutter grip trigger.
  • Enhanced resistance to hydrodynamic shock for use in harsh conditions.
  • The control buttons have a 70% increase in spring stiffness, offering better tactile feedback for precise control.
  • Please note: The upgraded housing version does not include a dedicated sync cable bulkhead. However, it can be purchased separately and installed via an M33 bulkhead interface.

Frequently Asked Questions

How deep can it go? +
The Salted Line housing is rated for depths of up to 40 meters (130 feet), ensuring reliable underwater performance.
Acrylic or glass dome port — which should I choose? +
Acrylic ports deliver solid image quality in most scenarios, and they have the advantages of being lighter, more affordable, and easier to repair. Glass dome ports, while offering slightly superior image quality in specific conditions and better scratch resistance, cannot be repaired if scratched.
6" or 8" dome — which size is right for me? +
The 6" domes deliver excellent image quality in most shooting conditions while being significantly more compact and travel-friendly, making them the preferred choice for many users. While 8" domes can offer slightly improved edge sharpness, their larger size makes them bulkier and less convenient to transport.
What is Surf Edition? +
Dome Ports include a lens shade that protects them from accidental contact with objects during use and offers benefits in some shooting conditions. The Surf Edition Dome Ports are designed without a lens shade to minimize drag when shooting in large waves.
What dome and flat ports are compatible? +
The housing uses a 90mm bayonet mount, compatible with all Salted Line / Sea Frogs dome and flat ports for that bayonet size.
Does it include a port? +
No port is included. Ports are sold separately.
What O-rings and maintenance is required? +
Inspect and lubricate the O-ring before every dive. Replace O-rings at least once per year or every 50 dives. Use only Salted Line / Sea Frogs silicone grease — third-party greases may cause leaks.
What makes the triple-latch system different? +
The A7IV Gen2 housing uses a triple-sided metal latch locking system, providing three points of secure closure for added reliability.
Can I connect an external monitor or recorder? +
Yes. The housing features an integrated M33 threaded HDMI bulkhead interface for use with external underwater monitors or recorders.
Does it support the Photo/Video/S&Q switch? +
Yes — a dedicated external switch allows you to change between Photo, Video, and S&Q modes without opening the housing.

UGG Comfort Without the Premium Price
Size: 9, Color: Beige, Size: 9, Color: Beige
These sandals are super cute and incredibly comfortable. They have that classic UGG look and feel, but at a much more approachable price point. The footbed is cushioned and supportive, making them easy to wear for extended periods. The straps feel secure without rubbing, and the overall construction feels solid and well made. They’re lightweight but still have a sturdy sole with good traction. They pair effortlessly with casual outfits and have that relaxed, elevated vibe UGG is known for—just without the higher price tag. A great value for both style and comfort.

Ugg comfy shoes
Size: 7, Color: Black
So comfortable and cute as well. I wore these the first time and had to have everyone touch them to see how the sole would squish. Fit well, and are lightweight as well.
