What a specific dive was actually like: the site, the water, the conditions, and how the system performed. Written up by the WOLACH team from real dives.
Tonghu Quarry: The First Cold Dive of the Year
A quarry lake in early spring, a walk-in over wet rock, and a layer at six metres that changes everything. What the S9 did on a day when nobody wanted to be first in.
Shuangyue Bay: Shore Entry With a Swell Running
A bay with two names for a reason, a shore entry that needed a second look, and a hose that spent the whole dive trying to tell us the tide had turned.
Sanmen Island: A Boat Day With Four Divers
One machine, four divers, two tanks of fuel and a very long lunch. What a boat day actually looks like when the surface unit has to keep up with a rotation.
Xiaogui: Rocky Shore, Poor Visibility, Good Day
Two metres of visibility, a rocky entry, and a reminder that the quality of a dive has very little to do with what you can see.
Quanmin Pool: Four First-Timers and One Machine
Two hours, four people who had never breathed underwater, and an interesting problem in rotating a single hose between them without anybody waiting around.
The Quarry in April: Machinery, Mud and a Very Slow Sweep
Warmer than March, worse visibility than March, and a full hour along a submerged rock face looking at industrial leftovers. A site that rewards patience and punishes fins.
Nanyou Pool: A Full Day of Getting Buoyancy Right
No depth, no current, no excuse. What a day of deliberately boring pool work fixed, and the number that surprised everyone.
Xiangyuan Pool: The S9’s First Day in a Lane Pool
A new machine, a measured lane, and the least glamorous useful thing you can do with a surface-supply system: run it against a load and write down what it delivers.
Swimming Hall: An Indoor Check on a Rainy Week
No weather, no swell, no excuse to skip the checks. What an afternoon in an indoor pool is actually for, and the three things it caught.
Nanyou in April: A Full Day of Testing Two Machines Back to Back
An S6 and an S9, the same lane, the same divers, the same afternoon. What actually differs when you stop comparing specifications and start comparing breaths.
