Thanks Jason in Enid, Would 100lbs be sufficient?
Thanks guys. I have three concerns. (1)Getting a magnet that adhears to an object too heavy for me to retrieve. (2)Magnet gets entangled or stuck in debris or underwater plants, rocks etc. I may look for getting at least two inexpensive magnets for back-up. (3) SAFTEY ( most important). Has anyone been seriously injured with 350lbs. Magnet? Thanks, Don
