    Carbon fiber reacts with stainless steel? . How long does that take? Mine has been in the surf for many years now and I haven't seen a thing......

    Yep it does. I race sailboats (and rigged professionally for a year) with carbon fiber parts that had stainless hardware, it all had to have a barrier of some kind between the two. CF and aluminum is worse. Rinsing it with freshwater goes a long way and even then it may never get bad enough to be an issue, but if you are putting it together yourself and especially if it needs a shim or spacer why take the chance?
    "Stainless Steel

    There is no evidence of the formation of corrosion for stainless steels coupled to carbon composite. However, it is reported that some types of stainless steels (such as types 410 or 301) are susceptible to localized corrosion (pitting corrosion and crevice corrosion) when they are connected to a carbon composite in aerated 3.5% NaCl (simulated seawater). It is believed that the pitting corrosion will be enhanced by increasing Ac/Aa. (For more information about pitting corrosion, see A Look at High Nitrogen Stainless Steels .)"

    Aluminum I can understand.....when it corrodes, it swells. I just haven't run across any stainless that did that. There are different alloys of stainless though, so, I guess it's possible with some of them. I have found stainless items that had holes corroded in them, but, they still hadn't swelled at all.......just eaten away.

    I guess you didn't read the quote or the link.

    Sure I did, I'm just saying that I haven't run across any situation where stainless swelled due to corrosion....and I've had carbon fiber handles on my stainless scoops in the ocean for years. I've also found lots of stainless fasteners and hardware from watercraft that show no ill effects from being in the ocean. I'm sure you can always find some combination of materials that will cause some sort of chemical reaction, I just haven't run across any of those situations. Probably a fairly rare occurrence or I guess I've just been lucky. Maybe in the boating community it's a problem, but, is it for us regular detectorist? Am I the only lucky one here? Has anyone else had a problem with stainless corrosion in their detecting equipment?
