Itching after diving

[ksloan]

My husband and I just started diving. During our classes, we did instruction in a pool. After the classes were over, he started itching all over but his chest and his ankles were the worst. We wore equipment from the dive shop. We then purchased our own equipment and practiced in another pool. The itching and rashes returned. We then did our open dive in a fresh water crater in Utah, the itching and rashes returned. We just finished diving a morning dive in the Florida Keys and the itching and rash has returned again! This last dive he also wore Rash Guard clothing between himself and his BC. He has alwo switched booties twice.

Can anyone help us? We want to continue diving but don't know what is wrong!!

Thanks,
Kim and Tim
