All the Trimmings: Tips to Improve Your Efficiency in Water with Good Trim

Scuba diver
With good trim, divers are more efficient and can stay longer and safer underwater.

Trim is a misunderstood, and often poorly rectified, scuba skill. In our scuba journey, trim is something that we may or may not encounter or discuss, unless we get into technical diving or more advanced recreational diving. Francesco Cameli offers insight and advice in how to improve your trim and increase your efficiency in the water.

Thermal stress

A rapid chilling of superficial skeletal muscles (conductive cooling) creates a crippling weakening.

Thermal issues affect the comfort, performance and decompression stress experienced by divers. The impact varies with the timing, direction and magnitude of the thermal stress. Thermal protection can be provided by a variety of passive and active systems. Active systems should be used with particular care since they can markedly alter inert gas exchange and decompression risk.

Technical diving instructor and inventor Gregory Borodiansky is qualified to dive 20 different rebreathers. He is also a rebreather instructor on many units and a rebreather instructor trainer. Since Borodiansky has a background in electronic engineering and computer science, he took the features he liked on each unit and designed a front-mounted rebreather. Larry Cohen reports.
