DIVE LIGHTS BUYING GUIDE
Do I Need a Dive Light?
If you're going any deeper than you would while snorkeling, it's probably a good idea to carry a dive light. Reason? Well, the deeper you dive, the more the water will filter out the sun's light. If you're diving in clear water, visibility will be better, but it's still a good idea to have a dive light. You may find yourself near a coral reef with large cracks and crevices that you'd love to peek into. Illumination is the only way.
Dive lights are also commonly used for divers to communicate with each other. It's a great way to get someone's attention under water. Whether you've just found something really cool, or you're running low on air and need an octopus; lights offer a way to flag down your buddy.
Should You Bring a Backup?
Answer: yes. It's always a good idea to bring backup – especially if you're diving deep enough to filter out natural light. Your backup light doesn't have to be as strong as the primary light, but there's no question that you should have one.
Most divers use a broad beam light for their primary light because they cover more area, which will allow you to see more of the ocean in front of you.
The backup light can be used to look at things closer to you, such as gauges and equipment, and they can also be used as backup (surprise, surprise) in the event that your primary light goes out. These lights are smaller and illuminate a smaller space than primary broad beam lights.
Are All Lights Created Equal?
Answer: No. But all lights are rated for depth, so you can get a feel for which will work best for your needs. It is extremely important to pay attention to this rating. If you dive to a deeper depth than your
light is rated for, your light might break when you need it most.
Steady Beams and Strobes
The steady beam is used most often under water to help guide the way or to see into cracks and crevices. As you can probably imagine, a strobe light wouldn't be nearly as helpful here.
On the other hand, if you're trying to grab the attention of a dive buddy, a strobe is perfect. Many dive lights offer settings for both, so you don't have to carry even more than a primary and a backup light. Just be sure to choose the right setting when you need it.
Dive lights don't always use the same type of batteries, but that doesn't matter much. All types are reliable. Just know which type your light takes and be sure to keep backups in your bag.
You can also purchase rechargeable batteries, but it is imperative that you keep backups charged and ready to go at all time. Rechargeable batteries do tend to be more expensive, and they have been known to diminish with each charge. But, they are a more eco-friendly option.
