Performance:

In the water you’d never guess the Zuma was a soft backpack BC. Its unique tank-security system — with a standard band positioned low on the tank and a smaller strap weaved around the valve — locks the cylinder in solidly without a hint of wobble. This not only makes the Zuma comfortable to wear, it contributes to its excellent stability at depth. “It’s virtually molded to your frame,” said one test diver. “No bulk, no wobble.” Testers found that the low-pro power inflator’s inflate/deflate buttons allowed for pinpoint buoyancy control. The SureLock II weight system also worked like a charm. Weight pouches — positioned well forward — self-align on a rail system, making them very easy to load when wearing the BC. Aqua Lung ratcheted up the system’s security by increasing the pull force required to release the pouches, but test divers found they still ditched easily. The BC comes with a very usable fold-down cargo pocket, four plastic D-rings for clipping extra gear and grommets for attaching a knife.

Bottom Line:

The Zuma was this year’s runaway favorite BC in the Travel category. It not only earned the first place spot on every test diver’s favorites list, but it also turned in the best ergo scores.

General-Purpose BCs
---
While they can be used for any type of diving, general purpose BCs are designed primarily for temperate- and/or cold-water diving with 7mm wetsuits or drysuits. General Purpose BCs tend to offer lots of buoyant lift across their size ranges along with heavy-load integrated weight systems. They often have large cargo pockets and larger D-rings for attaching additional gear.

Travel BCs
---
Travel BCs are lighter and more compact than General Purpose BCs. Many are designed to fold or stow in handy storage pouches for easy globe-trotting. Travel BCs tend to offer less buoyant-lift capacity and smaller weight pouches to suit warm-water diving scenarios.

Women's BCs
---
Women are shaped differently than men, so it makes sense that a women’s BC would be shaped differently too. Women’s BCs are often cut higher along the waist and are more expansive in the chest area. Straps and adjustments accommodate shorter, narrower torsos, and power inflators are ultracompact to fit comfortably into smaller hands.
