Safety Notice
Strong magnets can be dangerous if not handled correctly. It is essential that you read, understand, and follow all safety guidelines and warnings provided by us as well as manufacturers / suppliers of neodymium magnets. Deterioration of magnets and parts will also occur over time especially in saltwater. It is important to perform safety checks on the magnets and parts before and after each use. ​​​​​​SG Magnetics Pte. Ltd. is not liable for any damages, injuries, or death arising from the use of magnets and related parts.
Magnet Safety
Strong Magnetic Field: Keep away from pacemakers, metallic implants & other medical / sensitive devices or equipment.
​
Strong Magnetic Force: Wear personal protective equipment such as gloves or goggles when applicable. Do not place fingers or other body parts between magnet and magnetic surface. Keep away from objects or surfaces which are not intended for the magnet to attract to.
​
Keep Away from Children: Not for children <16 years of age. Do not swallow, do not inhale, do not insert into an body parts.
​
Do Not Allow Hard Impact: While these neodymium magnets have a hull to protect it or are coated in plastic/rubber, avoid hard impact whenever possible. Do not allow magnets to collide with each other or surfaces forcefully. Shattered magnets may result in projectiles which may cause injuries.
​
Do Not Modify Magnet: Do not attempt to pry or cut open the magnet coatings. Do NOT overtighten screw onto magnet, this will cause magnet coating to break or warp.
​​
Not Lifting Magnet: The pull force does not equate to how much it can lift. These are not lifting magnets and may not be suitable for lifting projects. These magnets are not certified for lifting.
​​
Keep away from heat: Max operating temperate <60℃, magnet powder should be kept away from flame or sparks.
​
Deterioration of Magnet: Due to the corrosive nature of saltwater, it is inevitable that the magnet will deteriorate over time. To prolong magnet use, exercise pre & post dive maintenance. Do not use if the magnet is damaged, if rust has formed from inside of magnet hull / on surface of magnet face or if magnet is found to be weakened beyond safe usage.
Magnet Storage & Limits
Note on Pull Force: The stated pull force is based on perfect tensile conditions. The pull forces were tested under the conditions: Pulled perpendicularly off large 2" thick clean, dry, smooth mild steel plate with whole surface of magnet in direct contact with metal, at low speeds <50mm/s at <20℃. The pull force will vary largely across different materials at different angles in different conditions. Over time, especially in seawater, the pull force will deteriorate.
Generally (but not a specific guideline):
150kg is for light duty usage - for light weight divers in low current conditions.
200kg is for medium to heavier weight divers in low-medium current conditions. This is the most popular option.
250kg is for heavier weight, stronger current conditions. For more extreme conditions, custom solutions can be provided. Please note that the above serves only as a general guide and the suitability of the magnet will depend on your individual usage and application.
​​
Maximum Operating Temperature: <60℃.
​
Storage: Keep dry and cool.
​​
Air-Travel: Not suitable unless specially packaged.
Pre-Dive Checks & Preparation
Ensure all parts secure - magnet, handlebar, screw, eyenut, etc are securely fixed in place without any loose parts. Any loose parts can be secured with a suitable thread-locker / sealant. Do NOT overtightened screw onto magnet, this will cause magnet coat to break or warp. Rubber grip may come loose over time, use reasonable means to secure if it comes loose or do not use rubber grip.
​
No physical damaged on magnet, handlebar, screw, eyenut or other parts. No cracks, breakage or warping of magnet coating. No rust coming from inside the magnet hull or on surface of magnet face. Screw not protruding out from magnet surface.
​​
No debris on magnet surface. Magnet surface is clear of debris and smooth.
​​
Holding Strength is still strong and over safe requirement for your job.
​​
Please see information sheet which comes with diving magnet purchase for additional pre-dive pointers to prolong magnet usage.
Post-Dive Maintenace
Remove all debris on surface of magnet.
​​​
Rinse well and soak in fresh water. Dry magnet after soaking and store in cool dry location​​
Operating Instructions
1) Tilt the magnet at 45° angle.
​
2) Lower the magnet slowly towards the surface.
​
3) Upon reaching the surface slowly close the angle between the magnet and surface.
​
Reverse the steps to remove magnet.
Do not slam or place magnet without angling the magnet as this may cause damages to magnet over time.
​
Do not place fingers, body parts or any unintended object between magnet and magnetic surface.
