Book Review: “Under Pressure – Diving Deeper with Human Factors” by Gareth Lock

We generally have one common goal in all our dive plans – getting back out of the water healthy and happy. But other goals can be important too! On a recent photogrammetry exercise, my scuba kit was checked and in good order, but I got into the water with a vacuum-sealed housing containing no camera – that dive could have been a disappointing waste of time, however safely conducted.
When things go wrong in diving it’s normal to identify a critical error and seek to identify – and blame – the individual responsible. This tendency can lead to a group’s collective actions and biases, in the lead-up to a particular failure, being ignored in the analysis. This hinders us in learning useful lessons and developing safer behaviours. In my case I have now written a “Stills Camera” checklist as well as one for “OC Scuba”; this should help prevent that ever happening again.
I make this embarrassing confession in the spirit of openness which Gareth Lock advocates in his important new book “Under Pressure – Diving Deeper with Human Factors”. This brings together years of work to examine the numerous non-technical skills which are required for successful activities in high-risk environments (specifically, underwater).
A “Just Culture” which promotes, rather than punishes, the sharing of experience is to all our benefit. Gareth has solicited a number of accounts of accidents, near-misses and bad situations from respected and experienced divers. These illustrate clearly the different ways in which human behaviours can lead to things going wrong, or to minor problems being compounded when they should have been handled. More importantly he introduces a number of tools and proposes an approach to the organisation of diving activities which enables all the participants to contribute to the safe execution of the dives and to perform as safely as possible.
This is a thought-provoking, absorbing and educational read which is relevant to any diver. I will certainly refer back to it and expect to read it again!

PADI and Scuba Diving Magazine Seek Incredible Underwater Photographs in Annual Photo Competition

Scuba Diving® magazine’s 21st annual Through Your Lens photo contest is underway and accepting images that highlight the incredible underwater world.
“Entering our Through Your Lens Photo Contest isn’t just about winning,” says Candice Landau, Content Director for Scuba Diving magazine. “It’s about beginning the journey of putting your work out there, sharing your unique perspective and realising just how much impact your images can have. With categories for all levels, including an amateur category specifically for newcomers, there’s a real chance to get noticed and inspire positive ocean change.”
“This year we decided to bring back a couple of tried-and-tested categories, as well as add two new ones. In total, photographers will be able to submit to five different categories: wide angle, macro, split shot, amateur, and cold water,” Landau says.
Scuba Diving has confirmed the return of highly esteemed underwater photographers Brandon Cole, Kate Jonker, Suzan Meldonian and Alex Mustard to assist as guest judges. Entry is free, and photographers can submit up to five entries per category.
The grand prize winner will receive a $1,000 USD cash prize and a weeklong liveaboard trip aboard the Komodo Aggressor. First-place winners for each specified category will receive an Aggressor Adventures liveaboard trip; second-place winners will receive a Scubapro regulator; and third-place winners will receive a SeaLife SportDiver S smartphone housing. Two winners in the Amateur category will receive a liveaboard trip from All Star Liveaboards. Select winners will also be given the opportunity to have their photos featured on PADI certification cards.
Past winners of the annual competition include colorful images of alpine newts on water lilies in Belgium, divers finning through a submerged Slovak opal mine, and an eye-to-eye encounter with a dwarf minke whale on the Great Barrier Reef.
“This contest is a chance to celebrate the artistry and passion of underwater photographers at every level. It brings the underwater world to the surface for everyone to see, and it’s always amazing to witness the creativity, dedication, and stories that these images tell,” says Landau. “It’s not just about taking a beautiful picture, it’s about capturing a moment that inspires others to dive, explore, and protect the ocean. Every submission helps us tell the story of the underwater world and why it matters.”
All winners and honourable mentions will be published in the September/October 2025 Photo Issue of Scuba Diving magazine, with the cover featuring one of the contest entries. Entries are open now until July 7, 2025 on scubadiving.com/photocontest.
