US Divers Non Magnetic UDT regulator #237601
The Exceptional Low Magnetism Regulator
Introduction to a Unique Regulator
Dive into the fascinating history of a regulator used by US Navy UDT (Underwater Demolition Team) teams to disarm magnetic mines. This regulator, with its extraordinary criteria including very low magnetism, stands out as an exceptional piece of diving equipment.
The Challenge of Magnetism
To safely disarm magnetic mines, the regulator needed to have minimal magnetism. Traditional chrome plating, which contains magnetic properties, was therefore unsuitable. Instead, corrosion protection remained crucial due to the regulator’s primary use in saltwater environments. Consequently, an alternative approach was necessary.
The Solution: Gold Plating
Gold plating emerged as the effective solution. Specifically, many critical parts of this regulator were meticulously gold-plated to ensure both corrosion resistance and low magnetism. For instance, components such as the nozzle (1012-12), the HP seat (1010-65), the spring block (1000-23), the LP seat holder (1010-04), and the LP seat retainer (1010-07) were all gold-plated. Notably, these gold-plated parts were distinctly marked with a circular groove, indicating their non-magnetic nature.
Unmarked Golden Mystery
In addition to the well-marked gold-plated parts, there is also a filter (1000-38) that appears gold-plated but lacks distinctive markings. This unmarked filter adds an element of mystery, inviting further exploration into the regulator’s history.
Distinctive Features of Non-Magnetic Regulators
Divers and collectors can identify non-magnetic regulators through specific features. For example, these regulators typically had an unmachined hook-ah port on the body. Additionally, the entire regulator featured a black oxide finish, serving both anti-glare and corrosion-resistant purposes. Thus, these characteristics set them apart from standard models.
Component Swapping Over Time
Over the years, many regulators have undergone various parts swaps. As a result, finding pristine, original specimens can be challenging. Nowadays, regulators might feature chrome or brass parts instead of the distinctive gold-plated components initially designed for low magnetism and corrosion resistance.
A Unique Piece of Dive History
Ultimately, the regulator used by US Navy UDT teams for mine disarming is a testament to innovation in diving equipment. Its specialized design not only allowed divers to carry out critical underwater missions but also ensured their safety and effectiveness.
