## Description

Product description

Review: OrcaTorch SD03 Review - 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.
Review: Night dive lighting problems - solved! - Last dive season I got cavern certified. One very important lesson in that class was reinforcement of a lesson from Deep diving class, the importance of lights. I had issues. Specifically, dissatisfaction with my primary and back up dive lights as well as with my dive beacon light. Let's talk beacon lights - the light most used on the cylinder & yoke/din primary regulator connection for night dives. In my deep class I invested, at the recommendation of my LDS in a not so inexpensive 3 light kit with a HUGE "primary" that reminded me of a 12-volt camping light, a bulky back up and a puny beacon light. After 3 years of intensive diving, the only one still in my kit was the beacon light. I was in hunt of a replacement for it as it only offered a weak white light with 1 mode, on or off. As a dive master, I am often asked to lead night dives, sometimes with people who are not night dive certified. Again, after months of research, I found a solution, the OrcaTorch SD03 Dive Beacon as it offered solutions to SO many issues that I had with my basic beacon. First 4 light colors; red, blue, white, and green. Additionally, any of the colors can also strobe on and off! This made it PERFECT for a group night dive. Everyone in my group was kitted with the SD03 and we set them all to the same color - blue. As the dive leader, I set my blue light to strobe. Strobe is a strong term here. It gently glows on and off, it's not a manic flashing back and forth. This enabled my dive group to stay together AND follow me as intended. It's compact - shorter than my index finger. Light weight - no noticeable impact on the weight of a dive kit. Long lasting -literature claims of 150 hours on a single AA battery. It's also the perfect brightness, easy to spot if you're staying buddy close but not so bright as to disrupt vision at night. I highly recommend this light to anyone interested in night diving or wanting a great visual aid for dive buddy recognition.

### ⭐⭐⭐⭐⭐ Reliable, Bright, and Perfect for Night Dives
*by W***M on May 11, 2026*

The ORCATORCH SD03 has become one of my favorite pieces of dive gear. For such a small beacon, it puts out an impressive amount of light. The 360° visibility is excellent underwater, and the four color options (white, red, blue, green) make it super easy to use for team signaling, positioning, or just staying visible in low‑light conditions. I really like how simple it is to operate — the rotary switch works smoothly even with thick gloves, and the mode memory is a surprisingly useful touch. The build quality feels solid, and the 150m waterproof rating gives me confidence taking it on deeper dives. It’s also lightweight and easy to attach to a BCD, tank , or backpack. Battery life is another big win. The long runtime means I don’t have to worry about swapping batteries constantly, and changing them is quick and tool‑free. For the price, this is a fantastic little signal light. Bright, durable, easy to use, and extremely versatile. Highly recommended for night diving, safety signaling, or as a backup light.
