48mm Double-Sided Fishing Magnet

This fishing magnet features a 48mm diameter magnetic body with magnetic attraction available from both main faces.

Unlike a conventional single-working-face pot magnet, a double-sided fishing magnet can attract compatible ferromagnetic objects from either of its main magnetic faces.

This can be particularly useful when the magnet is:

• Dragged horizontally
• Pulled across a riverbed
• Moved along the bottom of a creek
• Searched through sediment
• Used where the magnet's orientation may change during retrieval

Because either main face can encounter ferrous material, the double-sided configuration provides practical versatility for searching and dragging applications.

What Does Double-Sided Magnetised Mean?

Double-sided magnetised means the fishing magnet is configured to provide useful magnetic attraction from both main sides of the assembly.

This is particularly useful in magnet fishing because the magnet does not always remain in one fixed orientation while underwater.

When dragging the magnet across a search area, either main magnetic face may contact:

• Steel objects
• Iron components
• Tools
• Ferrous hardware
• Other compatible magnetic material

Double-sided magnetic attraction should not be interpreted as meaning that every surface of the magnet provides identical holding performance.

M8 Threaded Eyelet

The fishing magnet incorporates an M8 threaded eyelet, providing an attachment point for a suitable retrieval setup.

The eyelet can be used as part of a rope or recovery arrangement for:

• Lowering the magnet
• Dragging the magnet
• Searching underwater
• Recovering attached ferrous objects

Before each use, check that the threaded eyelet is correctly installed and securely engaged.

Threaded connections can loosen through repeated movement, vibration and changes in load direction, so the eyelet and associated retrieval equipment should be inspected regularly.

Neodymium Iron Boron Rare Earth Magnet

This fishing magnet uses Neodymium Iron Boron (NdFeB), one of the strongest commercially available permanent magnetic materials.

The high magnetic performance of neodymium relative to its size makes it particularly suitable for compact magnetic retrieval equipment.

NdFeB fishing magnets are commonly used for recovering ferromagnetic objects made from:

• Iron
• Mild steel
• Magnetic steel
• Compatible ferrous alloys

The specific neodymium magnetic grade has not been supplied and should not be assumed.

What Can a Fishing Magnet Retrieve?

Depending on their material, size, condition, accessibility and contact with the magnet, potential finds may include:

• Nuts
• Bolts
• Screws
• Steel tools
• Chains
• Ferrous brackets
• Steel plates
• Iron components
• Magnetic hardware
• Other ferromagnetic objects

Not every metal object is magnetic.

The magnet will not effectively attract non-ferromagnetic materials such as:

• Aluminium
• Copper
• Brass
• Plastic
• Timber
• Glass

Many stainless steel grades may also provide weak or negligible magnetic attraction.

Designed for Dragging and Searching

The double-sided magnetic configuration makes this 48mm fishing magnet particularly useful for dragging across an underwater search area.

Rather than relying on one magnetic face remaining pointed towards the target, both main faces can provide magnetic attraction as the magnet changes orientation.

Potential search locations include:

• Rivers
• Creeks
• Lakes
• Dams
• Ponds
• Drains
• Pits
• Wells
• Other accessible bodies of water

Always ensure that access and magnet fishing are permitted at the intended location.

Magnetic Pull Force vs Real-World Retrieval Capacity

No specific pull force has been supplied for this 48mm double-sided fishing magnet and a value should not be inferred from its diameter.

Even where a fishing magnet has a laboratory pull-force rating, that figure does not represent a guaranteed real-world retrieval capacity.

Magnetic pull tests are generally performed under controlled conditions using suitable steel with favourable contact between the magnet and target.

Real-world underwater retrieval is significantly more variable.

Factors Affecting Retrieval Performance

Actual holding and retrieval performance can be affected by:

• Target steel thickness
• Steel composition
• Object size
• Object shape
• Available contact area
• Surface flatness
• Rust
• Paint
• Protective coatings
• Mud and sediment
• Debris between the magnet and object
• Magnet orientation
• Pulling direction
• Mechanical leverage
• Water movement
• Object weight
• Objects being embedded or obstructed

A large steel object with poor contact may be more difficult to retrieve than a smaller object that provides clean, flat contact with the magnet.

Direct Pull vs Sideways Loading

Magnetic holding performance is generally strongest when the load acts in a favourable direct-pull direction.

When a fishing magnet is dragged sideways, the connection may experience:

• Shear force
• Sliding
• Leverage
• Uneven contact
• Changing load direction

These conditions can reduce practical holding performance compared with an ideal magnetic pull test.

This is particularly important when attempting to retrieve irregular, rusted or partially buried objects.

Rust, Mud and Sediment

Underwater ferrous objects are frequently covered by:

• Rust
• Mud
• Sand
• Silt
• Algae
• Paint
• Corrosion
• Other debris

These materials can create an air gap or physical separation between the magnet and target steel, reducing magnetic attraction.

Where possible, direct contact with clean ferromagnetic material provides stronger magnetic attachment.

Permanent Magnetic Operation

The fishing magnet uses a permanent neodymium magnetic system.

It requires:

• No electricity
• No batteries
• No charging
• No external power supply

Its magnetic field remains continuously active during normal use.

Selecting Rope and Retrieval Equipment

The rope, knots, connectors and other retrieval equipment used with a fishing magnet should be selected according to the complete application.

Consider:

• Expected loads
• Wet conditions
• Abrasion
• Knot strength
• Water exposure
• Retrieval distance
• Environmental conditions
• Potential shock loading

Inspect retrieval equipment before use and replace worn or damaged components.

The magnetic pull force of a magnet, where specified, should not be used by itself to determine the required rating of ropes, connectors or other recovery equipment.

Magnet Fishing Safety

Magnet fishing involves strong magnets, ropes, water and potentially hazardous recovered objects.

For safer use:

• Wear suitable protective gloves
• Keep fingers clear of pinch points
• Wear appropriate footwear
• Avoid wrapping retrieval rope around hands or body
• Take care around deep or moving water
• Inspect the eyelet and retrieval equipment before use
• Keep children away from strong neodymium magnets
• Use care when handling sharp, rusted or contaminated finds
• Do not place yourself in danger to recover a stuck magnet

Strong neodymium magnets can attract suddenly to nearby steel and may cause pinch or impact injuries.

Check Local Magnet Fishing Rules

Before magnet fishing, check the local laws, regulations, landowner requirements and access conditions for the intended location.

Magnet fishing may be restricted or prohibited in some waterways, heritage areas, private property or environmentally sensitive locations.

Permission may be required before searching from private land, bridges, docks or other structures.

Recovered objects should also be handled and disposed of responsibly.

Hazardous or Suspicious Finds

Magnet fishing can occasionally recover objects that may be dangerous.

If you retrieve or encounter an item that appears to be:

• Ammunition
• An explosive or suspected explosive
• A weapon
• A chemical container
• A potentially hazardous object
• Evidence of possible criminal activity

Do not unnecessarily handle, clean, dismantle or transport the item. Keep others away and contact the appropriate local authorities for guidance.

Please Note

This product is a Neodymium Fishing Magnet with a 48mm diameter magnetic body, M8 threaded eyelet and double-sided magnetised configuration.

Double-sided magnetisation provides useful magnetic attraction from both main magnetic faces, making this configuration particularly suitable for dragging and searching applications where the magnet may change orientation.

No specific pull force, Gauss rating, neodymium grade, coating or finish, overall height, dimensional tolerance or maximum operating temperature has been supplied and these specifications should not be assumed.

Any magnetic pull-force figure should not be interpreted as a guaranteed real-world retrieval capacity or safe working load. Actual retrieval performance depends on target material, steel thickness, available contact area, rust, coatings, sediment, orientation, load direction, water conditions and whether the object is obstructed or embedded.

This fishing magnet is not certified lifting equipment and should not be used for overhead lifting or safety-critical load handling.

Check local laws and obtain any required permission before magnet fishing. Handle strong neodymium magnets and recovered objects carefully, and keep magnets securely away from children, pacemakers and other medical implants, magnetic storage media and sensitive electronic equipment.
