Only if the person conducting the marketing efforts doesn't have a brain.
The way marketing is done - with a brain - is by doing the research to determine who has the greatest likelihood to be motivated (psychologically, not demographically), developing a campaign that speaks directly to them, and then targeting the execution of that campaign directly to them, with a specific, direct call to action to try your product. Doing all this increase your conversion rate at each step in the process
A broad, non-targeted campaign with an oblique message to try something else - that is NOT your product - in the
hope-against-all-logic hope that a handful of the people that may respond to THAT campaign will eventually go on to try your product aferwards is foolish.
Before buying a car most people have ridden a bike, right? Should GM promote cycling in order to drive car purchases?
Beer drinkers drank soft drinks prior to drinking beer, no? So Budweiser should promote soda?
However, that's not to say that snorkeling is not a good indicator of scuba interest. If there were a "Snorkeling Illustrated" magazine that would be a great place to advertise diving. But it would make little sense for DEMA to run "Try Snorkeling" ads in "Sports Illustrated" in the hopes that some of those people took up diving someday.

Where this breaks down for scuba is that golf's marketing machine does not promote golf. The machine promotes golf spectatorship... that's the product that the PGA sells. TV broadcast of golf is a multi-billion dollar business. But the dirty little secret about golf is that it's main business is NOT selling golf.
Look at who the BIG golf sponsors are. Advertising around golf is designed to drive CEOs to hire Acenture, millionaires to fly NetJets, affluent people to buy Rolex, business owners to offer Aflac insurance to their employees, upper-middle class people to believe that Buick is a luxury brand, get more MasterCard's in your wallet, drink Michelob, buy your wife a Tiffany bracelet, etc.
In fact, if you look at the PGA Marketing Partners listing you'll notice something very interesting...
Sales, Marketing, Partners
There's not A SINGLE company involved in the business of GOLF listed as a marketing partner!
Golf isn't a golf marketing machine... golf is a marketing machine to reach affluent customers for non-golf products. There's an incidental effect of promoting golf participation and gear sales. But you can rest assured that if golf relied on money from Titleist and Cleveland irons to promote the sport... there would be no machine.
