2.0 Key features overview
ONE160x is a professional underwater strobe with maximum energy of
157 Ws (J) and Guide Number 20 (ISO100-1m-full power). The beam
angle is 130° (GN16).
The body of strobe is machined from a solid block of anticorodal
aluminium, protected by a hard anodizing treatment with nanotech
quartz coating.
The depth rating is 200 m.
The strobe control is entrusted to a pair of powerful CPU that manage,
one the digital communication between the camera and the strobe, i-
TTL protocol by Nikon and E-TTL protocol by Canon, and the other the
power circuits in order to optimize the performances of the unit in
every situation, in addition to operational safety and battery life.

BASIC INFORMATION
The right INPUT lever selector allows us to select input and connection
mode that we intend to use: synchro cable socket, fiber-optic cable
socket, optical receiver on parabolic reflector for slave mode. The
control lamps indicate the selected SYN-OPT-SLV input.
The rotary control switch adjusts power output in manual mode or
exposure compensation in TTL mode. The selected energy level or
exposure compensation are clearly visible in the center section of the
wide display.
The lighting element is a professional and oversized circular flash lamp,
with a slightly warm coating, mounted on parabolic reflector with
dome port.
The strobe is equipped with a LED coaxial pilot light with two power
levels that can be selected manually or automatically with focusing.

Together with this information, all the indicator lights on the display,
MAIN section on the left and INPUT section on the right, light up at the
same time for a check.
The strobe is switched off by pressing the MAIN and INPUT lever
selectors simultaneously for a few seconds. A first beeping sound is
emitted after one second and keeping the pressure on the lever
selectors a second acoustic signal will warn that the lever selectors can
be released. The strobe will turn off after displaying the battery charge
status on the display.
i The left and right lever selectors, operated either individually or
together, give different commands depending on the operating
time that we can classify as short (one pulse) or long (one or more
seconds depending on the command).
