Review on MHDMAG Double Sided Magnet Fishing Kit With Grappling Hooks And Gloves, 760Lbs Combined Strength Super Strong Retrieval Neodymium Magnets With 100FT Rope For River Magnetic Recovery Salvage Fishing by Ricardo Thotti

Multiple test done in a controlled water setting (pool), pond/lake banks, off bridges ect as well as the same 25lb iron bar used in each. The pool test was fine. Magnet hooked on and it was an average of 70% of the pool test would hold and retrieve the iron bar. 30% the magnet failed. Ponds/lakes and bridges 100% fail. Dirt, and magnetic materials will stick and create further gaps between magnet surface resulting in failure.Overall, if your trying magnet fishing for the first time, and would be happy finding things like I have with this magnet, small objects such as old clothing buttons, watches, rusted screws nails small pipes. Other then really light objects, I would say this is only best to learn how to use a powerful magnet, thus when getting a stronger magnet you will know the do's and don'ts. The next magnet I've ordered is a Wukong 1700lb combined pulling force magnet. Well be here tomorrow, will test this as well. Not expecting much from it either but only way to know for sure is to purchase and try. I'd recommended this for beginners only.
