I used this a few days in the Bahamas, and from the time I used it in the water, let it sit on the beach for an hour, and took it home to rinse it with freshwater, some rust had already begun. By the end of the trip, it looked like it was a piece of steel left out in the elements for a year, rust pretty much covering all the prongs. I had rinsed the tip every day after using it, and really only used it two days, the rest of the time it stayed in the car. Nothing else on this trip rusted. I contacted Mako but they seemed to think it was a fluke, that all their tips were supposed to be made of the same grade stainless steel. Makes me question the rest of their tips, though I don't have any, so can't speak to them. Also, one of the prongs bent when it hit a piece of coral. Not impressed.

This thing is gnarly

Have not tried it yet but it looks like a killer.

Tip worked like a charm. I could not believe how affective the tip was I've penatrating and holding the fish!
