Frequently Asked Questions (FAQ)
Why is a 6.3-degree tight beam angle important for dive lights?
A tight spot angle (like the 6.3-degree beam on the BD40 PRO) is essential for penetrating murky water. Wide floodlights tend to reflect off particles in the water, creating glare (backscatter). A focused beam cuts through the water, making it highly effective for hole hunting, spearfishing, and spotting marine life hidden in crevices with your dive flashlight.
How deep can I take the Bludive BD40 PRO?
The BD40 PRO is professionally sealed and boasts a water pressure resistance rating of 150 meters (approx. 492 feet). This makes it more than capable for recreational scuba diving, technical diving, and deep wreck exploration.
What should you do if the BD40 PRO flashlight inside your diving bag accidentally turns on?
You don't need to worry about drained batteries! The BD40 PRO scuba diving torch features a smart Automatic Lock Function. If the flashlight is turned off for 3 minutes without operation, it will automatically lock itself. To unlock it, simply long-press the side switch for 2 seconds.
Does the BD40 PRO diving flashlight provide a warning before the battery runs out underwater?
Yes. The stainless steel side switch features a built-in accurate battery indicator. It shines Green (100%-30%), Red (30%-5%), and Flashes Red (5%-1%). Furthermore, the over-discharge protection will automatically downshift the brightness of your underwater dive light when the battery is critically low, giving you ample time to safely end your dive.
