The hugely popular OrcaTorch D710 dive light forms the basis for several variants. In addition to the D710, there's the D710V specifically for underwater photography and videography, the ZD710 with adjustable beam width, and the DC710, which can be mounted on the WS02 wrist strap or the H620 Goodman grip. So, if you want to keep both hands free while diving but still want a bright dive light, the DC710 is the right choice for you.
The OrcaTorch DC710 is quite similar to the D710 in some ways. When turned on, the D710 produces a bright, narrow (6°) beam of 1700 lumens, which can be boosted to 3000 lumens by holding down the DC710's switch. Alternatively, simply pressing the switch reduces the standard 1700 lumens in two steps to 800 lumens or 400 lumens. While it burns for one hour and 40 minutes at 1700 lumens, its burn time can be extended to 3 hours and 40 minutes at 800 lumens or even seven hours and 40 minutes at 400 lumens. The DC710 is equipped with a powerful 5000 mAh 21700 battery.
The difference between the D710 and the DC710 dive light lies not only in the ability to connect the DC710 to the WS02 wrist strap or the H620 Goodman handle. Charging is also different: The DC710 does not need to be opened for charging. The USB-C charging port is hidden under a 3 cm wide ring on the outside of the DC710. Turning the ring counterclockwise moves it downwards, revealing the USB-C port. Two O-rings are incorporated above the port to protect it from water, one of which is deliberately colored red: just to ensure that the ring is properly closed before entering the water. Keeping the USB-C port dry requires a little more attention from the diver, but if you handle your equipment carefully, it shouldn't be a problem.
