As any diver will tell you, perfect buoyancy starts with proper weighting. If you're tired of bobbing around like a surface marker buoy or feeling like you’re sinking like a stone, then it's time to rethink your setup.
Whether you’re just getting your fins wet or logging dive number 500, having the right weights in the right place can make or break your dive. From dialing in your trim to avoiding that awkward bobbing on the surface, proper weighting isn't just about comfort – it's about safety, efficiency, and making every underwater moment count.
So, let’s break down the essentials: from choosing between soft weights or lead blocks, belts or pockets, ankle or trim weights – and yes, how to calculate how much weight you actually need. We’ll also show you our most trusted and customer-favourite products from Mike’s Dive Store, where top-quality gear meets expert advice.
Why Proper Dive Weights Matter
Buoyancy control is the beating heart of good diving. Without proper weighting:
- You’ll struggle to descend.
- You’ll fight to stay off the bottom (hello, coral kickers).
- You’ll burn more air.
- You might even miss that all-important safety stop.
Worse, poor weighting can ruin your trim and leave you feeling like a floating banana. No thanks.
The goal? Start slightly negatively buoyant and use your BCD to fine-tune. Your weights should work with your gear, not against it.
How to Calculate the Right Dive Weight
Start With a Baseline
As a rule of thumb:
- In saltwater, start with 8–10% of your body weight.
- In freshwater, it's closer to 6–8%.
For example, a 75kg diver in saltwater might need around 6–7.5kg to get started. But that’s just a jumping-off point.
Factor in Your Gear
- Wetsuit thickness matters. A 5mm suit adds lots of buoyancy – you'll need more lead.
- BCD design also affects float. Older padded jackets may trap air; newer back-inflate models may not.
- Tank type – steel tanks are less buoyant than aluminium.
- Accessories – even things like your fins, lights, or camera gear affect how you float.
Buoyancy Test – the Real Truth
Here’s a classic diver’s trick: Gear up, head to calm water, deflate your BCD, breathe normally, and float vertically. When you exhale deeply, you should just begin to sink.
Too floaty? Add weight. Sink like a stone? Take some off. That’s your sweet spot.
Pro Tip: Always re-test your weighting when diving new equipment or switching from freshwater to saltwater.
Use a Buoyancy Calculator
If you’re new to diving or just want a quick starting estimate, a scuba weight buoyancy calculator can help. Many are available online – just plug in your body weight, suit thickness, water type, and gear setup, and you'll get a custom recommendation. But remember: calculators are a guide. Real-world testing is key.
Why Weights Matter More Than You Think
Weights aren't just dead weight. They're a precision tool. They balance the natural buoyancy of your body, drysuit, BCD, and tank. But it’s not just about how much lead you wear—it’s also where and how you wear it.
Whether you're trimming out for a perfect horizontal hover or reducing drag for long dives, weight distribution is everything.
