Product Information
The OrcaTorch SD01 PRO is a compact dive beacon and tank marker light that makes a diver easier to spot on night dives, group descents and low visibility dives. It runs on a single AAA battery (included) for about 37 hours in constant mode or about 70 hours in 1.5 Hz flash mode, measures 77.5 mm long by 19 mm in diameter and is depth rated to 150 m (500 ft).
Who it is for
This beacon suits recreational and technical divers who need a simple way to be identified underwater: night divers, dive guides leading groups, buddy teams descending a line together and anyone diving in murky or low light conditions. At 25 g it is small enough to live permanently in a BCD pocket, and it clips to a tank valve, BCD D-ring or harness with the included lanyard. Instructors and boat crews also use it as a marker so a specific diver or piece of kit stays identifiable in the water.
Key details
- Two modes: constant on and flash at 1.5 Hz.
- Runtime of about 37 hours constant or about 70 hours flashing.
- One AAA battery, included, so no proprietary cells or charger.
- Rotary on/off switch.
- 77.5 mm (3.1 in) long, 19 mm diameter, 25 g (0.9 oz).
- Depth rated to 150 m (500 ft).
Compatibility and sizing
Offered here in white, green or red. Each beacon emits one fixed color, so pick the color you want to be known by, or give each team member a different one. The slim 19 mm body attaches with the included lanyard to a tank valve, BCD D-ring or harness.

Frequently Asked Questions
How long does the OrcaTorch SD01 PRO run on one AAA battery?
About 37 hours in constant on mode and about 70 hours in 1.5 Hz flash mode on a single AAA battery, which is included with the beacon. Because it uses a common AAA cell rather than a proprietary rechargeable pack, you can carry spares on a dive trip and swap them in the field without a charger.
Can one SD01 PRO beacon change colors?
No. Each SD01 PRO emits one fixed color, so you choose white, green or red when you buy. Many buddy teams and dive groups order different colors so each diver has an individual signature light that is easy to identify underwater at night or in low visibility.
How deep can the SD01 PRO be taken?
The SD01 PRO is depth rated to 150 m (500 ft), which covers recreational and most technical dive profiles. Spare O-rings are included so you can keep the battery compartment seal clean and lightly greased, which is the key maintenance step for keeping any depth rated light watertight.
How do you attach the SD01 PRO to your gear?
Use the included lanyard to secure it to a tank valve, a BCD D-ring or a harness. The beacon is only 77.5 mm (3.1 in) long, 19 mm in diameter and weighs 25 g, so it adds almost no bulk or drag and can stay stowed in a BCD pocket until you need it.
