What are the lightest scuba fins?
Scubapro Go Sport Fin A lightweight, travel-friendly fin with a boot fit design and pre-angled blade. Training fins are rubber or silicone extensions that slip over your feet, making them longer and giving you more surface area to push against the water. Think of them like superpowers for your feet! They help you swim faster, kick stronger, and learn new skills more easily.For beginners, shorter swim fins can be particularly useful in learning proper kicking technique, improving kick tempo, and building leg strength without overly relying on the added propulsion of long fins.If you can’t wiggle your toes, the fins are too small. The efficiency of fins is largely determined by their size, stiffness and design. Divers with strong leg and hip muscles can efficiently use a bigger, stiffer fin. Smaller divers or less conditioned divers will be more comfortable with smaller, more flexible fins.A long or wide and rigid blade diving fin provides more thrust, but moving them requires more effort. If you have a thin blade, it will be easier to move but try getting out of a current with them.

What is the 120 rule in diving?
The 120 Rule is a quick mental math tool recreational divers use, mainly for planning repeat dives in a single day within moderate depths. Its core is simple arithmetic: for any single planned dive, your maximum depth in feet plus your planned maximum bottom time in minutes should ideally equal 120 or less. The 120 Rule in Diving Here’s how it works: the sum of your depth (in feet) and your no-decompression limit (NDL) time (in minutes) should not exceed 120. For example, if you’re planning to dive at 60 feet, your NDL would be 60 minutes (60 + 60 = 120). This rule helps ensure you stay within safe limits.Total time = Tank capacity / Air per minute. Using an 80 cubic foot tank at 3,000 psi: A diver with a SAC rate of 0. With an 80 cubic foot tank, they’d have about 53 minutes of dive time (80 / 1.
