5 of the 153 marinas and boating businesses we list in Marathon are scuba diving centers.

Diving centers vary significantly by their primary focus, ranging from retail shops offering open-water certification courses to charter operations running offshore dive trips. Choosing the right facility depends on whether you need gear rentals, local lake or ocean charters, or advanced technical training. A map location will not tell you if a shop operates its own dive boat, maintains an on-site fill station, or specializes in specific environments like wrecks or reefs.

Good to know

Do I need to own my own gear to dive with a local center?

Most full-service scuba centers offer complete rental packages including wetsuits, BCDs, regulators, and tanks. However, many shops require divers to bring or purchase their own personal fit items, such as a mask, snorkel, fins, and boots.

How long does it take to get open-water certified?

Basic certification typically takes three to four days spread over one or two weekends. It generally involves online classroom work, pool skill sessions, and four open-water training dives.

How much do local dive charters usually cost?

A standard two-tank local charter typically costs between $90 and $160, depending on the distance to the dive site. Gear rentals and tank fills are often billed separately if you do not bring your own equipment.
