While you needn’t break your budget for a snorkel set, it’s wise to avoid the cheapest supermarket sets, which are little more than toys. Typically, any set – mask, snorkel, fins, and carrying bag – that costs less than $25 is likely to disappoint. For a quality set with desirable features, expect to spend between $30 and $40 if you only plan to snorkel occasionally and $60 or more if you plan on snorkeling frequently and need higher-end features.
