ZD710 MK2 2-in-1 Zoomable Dive Light, 4-72 Degrees Adjustable Beam Scuba Diving Flashlight with 4 Modes, 920M Long Range, IP68 Waterproof Submersible Torch for Under Water Deep Sea Cave

I wanted an adjustable beam for my dives and paid a premium for this light. I also liked the 21700 battery with built-in USB charging, which can help in some remote situations. As with all Oractorches, the whole package has a premium feel. As expected, the wider openings work well, but the point beam is ugly and distracting. It is square-shaped, clearly showing 4 LED lights, their separations, dirt particles, and imperfections. The beam has a very pronounced yellowish hue at the edges, becoming more distracting as the beam narrows. Also, I didn't like the in-between size of this flashlight. It fits nicely in the hand but is too big for a pocket and small for a Goodman's handle. It's too early to tell, but the zoom mechanism appears short-lasting with many immersions, salt, and sand. Consider carrying two fixed lights instead of ZD710.

Purchased the Orcatorch ZD 710 MK2 light for a dive trip to Vancouver island in August of this year. The switch on the light failed after 9 dives, unfortunate but stuff happens. I contacted Ashley of Outdoor Equipment Experts and Ashley arranged to have the light replaced no charge. I received the replacement on October 14th and just got in the water with it yesterday. Light worked great, very bright and the adjustable beam makes it very versatile under water. This light made my backup light look dull. Thank you Ashley for the great service

Torch is excellent. Bright enough to shine to 3-4m comfortably to have a look from the surface. Then easy to adjust the light to suit when down in cracks.

This thing is a beast! The brightness is incredible - crisp, focused and cuts through water with ease. The zoom feature is smooth and practical, letting me switch from wide beam for exploring to a tight spotlight when I need to see details up close. The quality of this torch is rock-solid! I love that it doubles as both a dive light and a handheld flashlight, all while remaining lightweight and easy to maneuver - it’s truly versatile! The battery life is excellent and it charges quickly. The torch never gets hot to the touch or anything else like some do. If you are looking for a reliable, high performance dive light that is a fantastic value for the cost and delivers serious illumination underwater and topside, the OrcaTorch ZD710 is absolutely worth it. Five stars all the way!

As a diver who regularly uses primary corded lights like the tried and true Focus 2.0, I went into the OrcaTorch ZD710 mk2 with realistic expectations. Surprisingly it exceeded them. The first thing you notice is how much lighter and more compact the ZD710 mk2 is. Being fully handheld, it’s far less cumbersome on certain dives and when traveling. Built quality is nice and the zoom ring rotates smoothly with good resistance. The affordability also makes it an easy addition to any serious diver’s kit. Beam quality is where this light really stands out. The ZD710 mk2 has a noticeably tighter beam angle with a brighter, more defined hot spot than the Focus 2.0, which translates to excellent signaling and punchy visibility even in low vis environments. It obviously isn’t trying to replace your corded primary with a much larger or e/o battery for long deep cave penetrations. Instead, it excels as a great option for shorter cave dives, as a compact redundancy light source, and for the majority of real-world diving situations like most open water dives. Overall, OrcaTorch ZD710 mk2 is an outstanding option and an impressive piece of gear for the price.

If you can afford only one dive light, consider this one. It’s a little larger than some, but you get an amazingly versatile tool. First, it can be handheld, mounted on the back of your hand or on a one inch photo/video mount. It zooms in and out from 4 to 72 degrees which makes it great for everything from signaling and pointing to lighting up a huge space (think cavern/cave or wreck) and night diving. The reflector is high quality and doesn’t create any hot spots so you can use it for close photo or video work. The two supplied rechargeable 21700 batteries will keep it going for a long day (or night) in the water. The light can shine for up to 12 hours on the lowest setting! The side switch selects four brightness levels and shows you the current battery strength. It can also lock the light to avoid accidentally turning it on during travel. The hefty feel of the build is very impressive, using high quality aluminum and a very durable finish. There is a rear attachment point if you want to use a clip to keep this on your harness but do yourself a favor and check out all the great accessories that Orcatorch sells for this awesome light. I wish this had been available when I started diving. It would have saved me time and money.
