説明
Water takes what it is given. Retrieval is a separate discipline.
A salvage magnet is not judged by the force printed on its box. It is judged by how much vertical pull it still holds after a season of grit, rust, and riverbed abrasion. This unit is a sintered N52 neodymium block measuring 60 mm across and 15 mm thick, rated at 400 lb of vertical holding force against a 30 mm steel plate, with a practical pull capacity of around 150 kg under controlled conditions. Both faces attract, so the load is taken across the full mass of the magnet rather than a single edge.
The kit pairs the magnet with a 20 metre salvage rope, a claw attachment, and an eyebolt, which means it arrives ready for the work people actually buy it for: recovering tools dropped from a dock, keys lost off a bridge, and whatever else the river is holding. Treasure hunters who work a shoreline also use it to sweep for small ferrous finds. The steel housing protects the neodymium core on contact, which is what keeps the rating meaningful rather than theoretical.
Some things are not lost. They are simply waiting at the bottom of a river for the right magnet.

Who It Is For
The obvious buyer is the angler who has watched a knife or a rod holder disappear over the gunwale, and the diver who works shallow structures where a hand search is impractical. Beyond hobby use, maintenance crews use a magnet of this class to fish dropped fasteners and hand tools out of service pits and drainage channels before they reach pumps, and to sweep dock edges for scrap. Because both faces attract, it can also be mounted to hold steel fixtures temporarily during welding or assembly work in the field.
For anyone working a shoreline or a dock edge, the practical routine matters as much as the printed rating. Cast upstream of the target and let the current carry the magnet across the debris field, then draw it back slowly and steady rather than fast. A slow retrieve gives the rope time to load evenly, which is what protects both the line and your grip when a find turns out to be heavier than expected.
Frequently Asked Questions
Q: How much weight can it actually lift?
The 400 lb figure is the vertical holding force on a clean 30 mm steel plate. In real conditions with paint, rust or uneven contact, expect roughly 150 kg of usable pull, and less if the surface is thin or layered.
Q: Will it work through paint or rust?
It will hold, but every millimetre of coating or corrosion reduces the force. For maximum grip, clear the contact point down to bare steel with a scraper or wire brush.
Q: Is one face stronger than the other?
No. Both faces attract, so you can orient the magnet for the easiest release. Pull directly away from the surface rather than sliding it sideways.
Q: Is the rope strong enough for the magnet rating?
The kit rope is supplied for this magnet class and is rated well above the practical pull capacity. Inspect it for abrasion before each recovery session and replace it if fibres are cut.
Q: What can it be used for besides fishing?
Dropped tool recovery, treasure hunting along shorelines, clearing ferrous debris from service pits and drainage, and holding steel fixtures temporarily during fabrication.
Q: How do I release a find once it is attached?
Do not pull the load sideways. Steady the magnet flat against the object, then draw it straight away from the surface, or slide it to the edge so the contact area reduces first.
Q: Will salt water damage the magnet?
The housing protects the neodymium core, but salt water attacks any exposed coating over time. Rinse the magnet in fresh water and dry it thoroughly after every session in the sea.
