We use MAGNETS and no catches

February 27, 2014

One of the really great features of all Javelin Bipods is that they make use of very strong magnets in place of using clunky catches, adjusters and springs. What this means is that when in the field, setting up can be quick, quiet and spontaneous. The very smooth, quick attachment method and easy action of our bipods mean that they can be easily attached and setup in cramped, dark, damp conditions so you can concentrate on the shot, and not get distracted setting up.


Mere seconds can make the crucial difference between getting ‘that shot' and not getting a shot at all!


Why use magnets?

The magnets used in all Javelin Bipods are rare-earth very powerful neodymium magnets (NdFeB), and are made from an alloy of neodymium, iron and boron to form ​one of the strongest type​s​ of permanent magnet made.​ Neodymium magnets have replaced other types of magnet in the many applications in modern products that require strong permanent magnets, such as motors in cordless tools, hard disk drives and magnetic fasteners.
Neodymium magnets? A magnet is a just a magnet, right?
Wrong! ​The crystal structure of Neodymium has exceptionally high uniaxial magnetocrystalline anisotropy​. This gives the ​magnet the potential to have high coercivity (i.e. resistance to being demagnetised).
The crystal structure of Neodymium also has a high saturation magnetization - the inherent ​magnetic phase has the potential for storing large amounts of magnetic energy ​for a small given size, considerably more than samarium cobalt (SmCo) magnets, which were the first type of rare earth magnet to be made available commercially.
When comparing magnets, the following properties are crucial:
Remanence: which measures the strength of the magnetic field.
Coercivity: the material's resistance to becoming demagnetised.
Energy product: the density of magnetic energy​.​
Curie temperature: the temperature at which the material loses its magnetism.

Neodymium magnets have higher remanence, much higher coercivity and energy product, but often a lower Curie temperature than other types. Therefore Neodymium is alloyed with terbium and dysprosium to preserve its magnetic properties at higher (human friendly) temperatures.

All these factors make Neodymium magnets the perfect fit for use in our Javelin Bipods: small, very powerful, sturdy and long lasting.
