Triopo TR-180 Flash 300W GN60 for Nikon

Triopo TR-180 Speedlite Flash for Nikon cameras.
TR series: High performance, high compatibility, high power flash output.
Wireless trigger sensors: CELL2 remote sensing mode for off-camera TTL flash synchronization.
Increased external power socket: the TR series adds an external power socket.
Quick recall: full output only 2.9 seconds recycle time, not applying new battery can also recall to achieve fast speed, only 4-5 seconds.
Supports high-speed continuous shooting: 1/16 and below brightness, TR series to support high-speed continuous shooting 12SEPS.
Power-saving mode: when the flash has no action, the backlight turns off after 20 seconds, 60 seconds when the flash is not working, the CPU automatically shuts down; if it does not work for more than 30 minutes, the CPU automatically shuts down.
High precision output: From 1/128 to 1/1, 8 stops to lose, each stop has two fine-tuning compensations.
Overload protection: Ambient temperature detection (thermal protection)
Supports second curtain synchronization: uses a slow shutter for creating a smear object, the flash will fire from the moment the shutter opens, this is the rear curtain sync functionality

  Useful Information:

  The flash is one of the most hated/loved things in the world of photography. Hated because it requires mathematical calculations that are not always possible to do quickly "on the spot," loved because it allows you to photograph even when the human eye cannot even distinguish the simple shapes of an object. However, it is also one of the simplest tools to use, at least if you don't opt for very sophisticated (and expensive) models: all of them have at least one exposure automation, and some are even able to communicate with the camera and emit the right light without needing any other manual intervention from the photographer.
