Ideal for magnet fishing and retrieval

The Niuknow NIUKNOW888 is a single neodymium fishing magnet built for underwater recovery, metal scavenging and general item retrieval. Its 2.36 inch diameter and 500 lbs pull rating suit hobbyists and professionals who need a compact, high-strength tool for pulling ferrous objects from water or lifting heavy steel items in a workshop. The triple-layer Ni+Cu+Ni coating resists corrosion during repeated submersion.

Pull force decides suitability

The headline specification is the 500 lbs maximum pulling force measured under ideal conditions. This figure determines whether the magnet can handle the target object; actual hold strength drops with air gaps, surface coatings, rust or non-flat contact areas. Buyers who need guaranteed lift on irregular, painted or heavily corroded surfaces should verify the real-world margin before committing.

Handles medium ferrous loads.

The magnet comfortably retrieves tools, fasteners, small safes and similar steel objects that present a clean, flat mating surface. It runs out of effective grip on large irregular items, thickly painted structures or objects where only edge contact is possible. The single eyebolt mounting point also restricts use to single-line pulls rather than multi-point rigging.

Questions about this item

How much pull force will the 500 lbs rating actually give me on a real underwater recovery?

The 500 lbs figure is measured under ideal conditions on a thick, flat steel plate; on rusty, curved or thin objects the effective pull will be lower, so use a strong rope and expect less force in practice.

What does the Ni+Cu+Ni triple coating actually protect against in saltwater?

The three-layer nickel-copper-nickel finish resists rust, scratches and general wear, keeping the neodymium core sealed during repeated saltwater exposure.

What size rope or bolt fits the internal threaded hole and eyebolt?

The magnet includes an eyebolt that screws into the internal threaded hole, allowing direct attachment of a carabiner or rope loop without extra hardware.
