I find it very hard to sell a used wetsuit. If you do it’ll be basically a give away. New divers rent for a short time until they find out what happens with a sponge diaper. It’ll be hard to even give it to a seasoned diver. Wesuits/Diveboots are all to hard to get rid of. Also they have to fit the buyer which is usually what happens after waiting for someone to show at the house. 80% of the time it won’t fit. If it does fit then your asking price will be cut so low. Your better off enjoying your free time. Donate it to a dive organization that is profit free helping out divers with some type of dis ability. I think your husband would appreciate that much better.
