Diver Magnet - 230
Twin magnet: two Ø60 magnets under one handle, for more grip against sliding on curved or uneven steel. Need the most pull from a single magnet? See the Diver Magnet – 250.
The Diver Magnet – 230 is a high-performance subsea magnet designed for medium-to-heavy commercial diving operations. It provides strong, dependable holding power on ferrous structures, helping divers maintain stability while working with tools, performing maintenance, or operating in moderate currents. The assembly features a high-strength neodymium pot magnet for secure adhesion, a stainless steel eye nut for attaching tools and lanyards, and a stainless steel handle that provides a firm grip and controlled leverage for safe detachment once the magnet is fully engaged. Durable and corrosion-resistant, the Diver Magnet – 230 is built to perform reliably in demanding subsea environments.
Pull Force: 230 kg · Magnetic face Ø: 2 × 60 mm · Grade: N42 · Coating: Epoxy-HDPE · Depth: proven in service to 150 m · Country of origin: South Africa
The Diver Magnet - 230 is a professional-grade neodymium pot magnet rated at 230 kg pull force — the go-to choice for commercial divers who need reliable tool anchoring, equipment staging, and general subsea operations. Manufactured by Diving Magnets (Pty) Ltd in South Africa with Epoxy-HDPE coating for corrosion resistance and 316 stainless steel hardware, this diver magnet is trusted by commercial diving professionals worldwide.
What is the Diver Magnet - 230 used for?
- General commercial diving tool holding on pipelines and structures
- Underwater inspection and NDT (Non-Destructive Testing) equipment staging
- Securing medium-weight tools during hull cleaning and maintenance
- Subsea welding habitat setup and equipment positioning
- Offshore platform maintenance and repair operations
Features & Benefits
- 230 kg rated pull force — reliable for most commercial diving tool holding applications
- Magnet sealed in epoxy and HDPE for continuous saltwater use
- 316 stainless steel eye nut and handle hardware — highly corrosion-resistant in marine environments
- Controlled detachment mechanism prevents accidental release during operations
What surfaces does the Diver Magnet - 230 work on?
Works best on
- Mild steel and carbon steel (best performance — flat, clean surfaces)
- Cast iron structures and components
- Structural steel beams, columns, and plate
- Steel pipelines and risers
- Ship hulls and marine vessel steel
Reduces performance
- Rusted or corroded surfaces — rust and scale create an air gap that reduces pull force
- Painted or coated surfaces — coating thickness creates an air gap
- Curved surfaces — reduced contact area lowers effective pull
- Thin metal (under 5 mm) — insufficient material for full flux path
Will not work on
- Aluminium, brass, copper, and bronze (non-ferrous metals)
- Most austenitic stainless steels (304, 316) — little or no attraction, slightly magnetic only where cold-worked or welded
- Concrete, wood, plastic, fibreglass, and composites
- Titanium and non-magnetic alloys
Safety Guidelines
- Always wear protective gloves when handling magnets rated above 100 kg pull force — pinch injuries are the most common hazard
- Keep magnets away from dive computers, compasses, and electronic instruments — strong magnetic fields can cause permanent damage
- Never allow two magnets to snap together uncontrolled — the collision force can shatter the magnet and cause flying debris
- Use a safety lanyard to secure the magnet to your harness — prevents loss in current or during detachment
- Attach at a 45° angle and rotate flat — never approach a steel surface head-on with a strong magnet
- Brief your dive team on magnet location — unexpected strong pull near steel structures can trap equipment or limbs
Care & Maintenance
- Rinse thoroughly with fresh water after every saltwater use — salt crystals accelerate corrosion if left on the coating
- Dry completely before storage — moisture trapped against the magnet surface causes coating breakdown over time
- Inspect the Epoxy-HDPE coating regularly — any chips or cracks expose the neodymium core to corrosion
- Remove iron filings and metal particles after each use with a wire brush or cloth — accumulated debris reduces pull force
- Store in a cool, dry environment away from electronic equipment — temperatures above 80°C permanently reduce magnetic strength
- Apply a thin layer of corrosion inhibitor (light oil or silicone spray) for long-term storage
The all-rounder for professional commercial diving
- Working commercial divers who need a reliable daily-use magnet
- Dive companies outfitting teams for general offshore maintenance work
- Operations requiring 230 kg pull force for medium-weight tools and equipment
- Inspection and NDT teams who need dependable staging on steel structures
- The most popular choice among professional dive teams worldwide
