ORCATORCH SD03 Dive Signal Light 4-Color-in-1 (Blue, Red, White, Green) 8 Modes Scuba Diving Beacon with Constant and Flashing Modes, Mini Scuba Tank Marker Light for 100M Underwater Diving

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.

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.

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.

The cool thing about this light is the ability to change the colors and make them solid or flash. It has has a built-in low lumen flashlight. In m video, I compare it to one of my other tank lights. I've been told my other light can be seen pretty far away. This light is almost as bright. My other light can't flash and the mfg doesn't make them anymore. I can change colors on it, but it's a pain. With the Orca light, switching modes is pretty simple. It took me a second to figure out how to change the mode. What you do is tighten the light until it turns on, loosen till it turns off and tighten it again back on right away. If you do the off/on switch fast enough, it will switch modes. I didn't try switching modes underwater on my first dive with it. I attached it to my flag reel so that I could compare it to my other light. Another huge advantage of the Orca light is that it requires a single AA battery. My other light requires 4 AAA batteries. This requires charging 3 fewer batteries! It doesn't sound like much, but when I have to charge flashlight batteries, strobe batteries, camera batteries, etc., any reduction in the qty of batteries required to charge is a bonus. I also own the Orca SD01 tank light, but I attach it to my dive flag. It's small and light. This light would be a little too heavy to put on my dive flag. If I could request one feature, it would be that it be positively buoyant. Most lights aren't though.
