Used but is working I’m pretty sure you would have to get it updated before you can put it on a vessel. I think you sent it in somewhere.
Because this is a crucial piece of life-saving equipment, I want to be completely upfront: the battery label is visibly dated 12/2010, which means it is long expired and absolutely must be replaced before you can trust it on the water.
Professional Servicing: Having an authorized center replace the battery, swap the gaskets, and fully test the unit typically runs between $125 and $300. Some dedicated EPIRB shops charge a flat rate of $249.95 specifically for the RLB-35.
