This is a must have for night dives. You and your buddy will know where you are at all times. Having different colours to identify each buddy pear. You shouldn’t lose them with this.

Desafirunadamente mi opinón es mala al producto ya que tenía buenas referencias por lo que hice la compra, desafortunadamente no funcionó la lámpara por lo que la valoración es mala. Ojalá que sus estándares de calidad mejoren.

SD03: SD03 Dive Beacon I'm always looking to increase my visibility and preparedness. The SD03 Dive Marker does both. It can provide a visible strobe for others to see you or can be used as a backup flashlight. Both are important items to have but in this case, incorporated into the same device. I took the SD03 on some cold dark dives here in the Pacific Northwest as well as a week of warm water diving in the caribbean.  Overview: So how did the SD03 Dive Beacon do? In the case: It comes in a box with spare o-rings, a single aaa battery, a lanyard, a user manual and a warranty card. Build and design: The overall quality feels solid in hand. The threading screws together with ease. It came with lubricated double o-rings that should help keep it watertight at 100m depth. Depth Rated 100m Size: 76.15mm (Length)* 30.5mm(Diameter) * Net Weight: 50g without battery Power: It’s powered by a single AAA or rechargeable lithium 14500 battery. I chose to use a Vapcell H10 14500 Purple/White 10A Button Top 1000mAh Battery Max Runtime: 250 hours (Battery dependent) Simple: The light is intuitive and easy to use. Simply twist on and off. It can emit light in 4 different colors and has 8 lighting modes: for each color either constant light or flashing mode. Both color and light modes can be chosen by rotating the body. The mode used for more than 3s will be memorized, when you turn it on, the SD03 will start to cycle from the memorized mode by default Attachment points: There is a single attachment point on the tail of the light. You can use the provided lanyard. My only concern is the plastic used for the attachment point. The plastic could snap under force or if dropped. Metal would be a better option. Finish: The finish shows little wear after multiple dives. Final Thoughts: Pros: -Bright and sustainable output. -Good colors for underwater use. -Good Size. Small enough to travel with. Very lightweight. -Twist On/Off for easy use. -Includes one aaa battery -Long runtime allows for multiple dives before needing new batteries. -Adds safety to any dive -100m rated depth makes this usable to technical and recreational divers. -Good value -Great emergency backup light Con’s: -It should come with a rechargeable 1000 mah 14500 battery. -Flashing pulse speed is not controllable. It is faster than I would prefer. -Im concerned the plastic attachment point will break. Metal would be more appropriate -There should be a white flashing option on the body like the other colors -The light is significantly brighter with a 14500 battery. AA output is dull in comparison.

I bought the Orcatorch light for a few key reasons. My dive instructor recommended having a reliable light for our certification dives in a local lake with decent but not exceptional visibility. I needed something recognizable, highly visible, affordable, and durable. As a fan of DiveTalk on YouTube, where Orcatorch lights are frequently praised, I already trusted the brand. I’d also purchased an Orcatorch DC710 during Prime Day, which impressed me with its brightness and quality, so sticking with Orcatorch was an easy choice. During our two-day certification dive at Lake Pleasant in Arizona, the light performed flawlessly, ticking every box on my wish list. It was bright, reliable, and perfect for the conditions. However, during a fun dive in Mexico over Labor Day weekend, the light began acting up. It worked intermittently, wouldn’t change colors on command, and occasionally turned on randomly. Thankfully, during a guided night dive, it stayed on and glowed green for the entire dive, saving the experience. When I got home, I contacted Orcatorch support, sending photos and videos of the issue. Their team was responsive, quickly coordinating with their Amazon seller, who shipped a replacement within a week. Overall, I’m a big fan of this light (and my DC710). It’s bright, easily visible underwater, stylish, and reliable enough to serve as a backup if my primary light fails, ensuring a safe return to the boat or shore. I highly recommend this Orcatorch light—or any of their products—to anyone seeking a robust, budget-friendly dive light.

This is bright, allows you to select different colors or white, Flashing or solid. Long Battery life. Just 1 AAA battery. It works a lot better than a much more expensive strobe light. The great part is you and your partner can pick colors other in the group don't have. This is really great for night dives and identifying your partner. It's small and compact yet bright. I own one and bought one for my son to replace the crap strobe light.
