Strobes are a useful (I would call them essential) tool for divers. I never conduct a dive without at least one strobe and I usually have 2-3 on a dive. I think of strobes as the proverbial “bread crumbs” to find your way home.
I almost always put one on the “down line” to a site to help orient and find my way back to the line for my ascent and decompression. I have used them in caves and wrecks to mark a position. I also use them to mark a “rich gas” bailout cylinder that I might leave outside a wreck.
I have quite a few Big Blue video lights that I use for deep water photography and videos so I was excited when they announced that they were introducing a new strobe.
The key to a good strobe is that is has to be bright and it has to flash for a potentially long time.
On my recent exploratory dives, I took a newly introduced Big Blue strobe to test it out.
It was really bright.
On the video below, I was 200 feet deep in conditions that were probably 20-30 feet of visibility and I could clearly see the light that I placed on the downline from at least 50-60 feet away. I probably could have seen the light from 100′ feet away. It is very bright.
Overall, I definitely recommend the new Big Blue strobe. The “pros” are that it is very bright, it is built very well and can stand the abuse of a wreck diver and a deep diver, and it uses a “standard” 18650 battery which most of my other lights use. About the only downside is that it is more expensive than other strobes that I have, but you pay for quality.
Disclosure: I was not paid by Big Blue for this post. Big Blue provided Tyler Stalter with a couple strobes for testing and he gave me one of them for these dives.
