I think you’ve had a similar experience with Rainbow Reef as I have had. Their dive process is as Disney-ified as their website. That is *not* a knock on them. Disney is one of the most popular attractions on earth. It’s not a bad model to emulate. But if you’re *not* a Disney person (for...

Conclusions As mentioned, this review comes from an unusual perspective: a technical diver looking for better backup lights. My thoughts are mainly focused on this use, but I've tried to detail how the light might work for a recreational or new-to-tech diver so you can apply this to your own...

Runtime - Part 2 Here is the fish-killer running for 115 minutes compared to the OrcaTorch with a fresh battery on High, to compare to our starting brightness: 115 minutes, OrcaTorch with fresh battery on High So, it turns out the alkaline battery light is down a good amount too. In fact...

Runtime Brightness is certainly important. Runtime is pretty important too, though. What can we expect from this light? The manual says 125 minutes on high. I'm reluctant to simply trust that number: I need to be able to count on what this light will deliver. So, I turned the light on...

Using the light underwater ETA: I'm pretty sure the batteries in my fish-killers were lower than I thought they were. I did not put fresh batteries in them for this trip. I absolutely should have done that. Seeing the results from the runtime testing made me realize that the results here...

Light prep and initial impressions The first thing I did was charge the battery overnight. That gave me plenty of time to get familiar with the manual and prep the light. The manual was noticeably above average: it still felt translated, but mainly because the language was more formal than a...

Purchase, unboxing and accessories I ordered the light on Amazon. Because of the review process, there were a couple of extra non-Amazon hoops to jump through that a normal buyer would not have. I had issues with that part and OrcaTorch jumped in quickly and effectively and helped me to...

OrcaTorch D550 1000 Lumen Handheld Dive Light Review The OrcaTorch D550 is a 1000 Lumen handheld dive light with a metal body and a pushbutton switch on the end, and uses a single rechargeable 18650 lithium battery. It's a very popular format for dive lights. When OrcaTorch offered a free...

Hey, that’s cool. The Amazon thing is probably the bigger deal, both for you and for prospective customers. But I’m much more curious about the canister on a DSV. Was that like a stunt to see if the canister would work, or is that some scientist needing to store something outside of the DSV and...

Wow. My reaction is the exact opposite of the sentiment that I'm getting from the replies above. DAN acknowledges *several* 'deviations from SOP' in this case, or requirements that clearly worked against the victim either by them or their selected transportation provider (for which they bear...

The owner does not have to be the one to renew it. I’m sure it makes it a little easier, but there are some renewals that have been handled by PSI, which is not a tank manufacturing organization. :) DOT has made it very clear that they do not want this to lapse. They have stated that they will...

I have to say I’m not following this. I have two conflicting prejudices here. First of all, I dive Jets, both extra large and 2xl. I have very high arches, so the foot pocket can be punishing. But with the right shoes underneath, I find them to work extremely well, especially with a dry suit...

IMHO, no compressor should be without continuous CO monitoring. Take an old first stage, plumb into compressor output, use a 3 lpm flow meter to blow on $100 CO detector. Even if you had to buy an old first stage, $200 or less. Link to $100 CO detector review: Forensic Detectors Carbon...

Which to my understanding would be relevant if I were asking about water inside my first stage. But I can’t figure out how that is relevant for how water got inside the face of my SPG. Your point is valid and accurate, but as far as I can tell not related to my question. The only reason I’m...

I haven’t watched the video but I’m not sure how pressurizing the air path will affect water under the glass. The water in the gauge body isn’t entering from the air path — if it could, then air could get out, and there’s no bubbles. But either way, these regulators are never soaked. You know...

I just got back from a trip and I now have *2* gauges with water in them. They’re both 2” gauges: one a HOG and one a DGX. I think they’re both made in Italy, so likely the same (rebranded) gauges. So, if I want to replace these with something less likely to break, what do I buy? I like the...

The weird part is the variability. I live in the Detroit, Michigan area. When I did my ice diving class we had more than 12 inches. Last year we never even had 3 inches all winter — and I’ve found from personal experience that 2 1/2 inches is not enough. :-( And yeah, unless something changes...

What’s the price range for a Gavin? I have an original PVC Gavin from 2003. It runs fine, but the runtime is down to about 45-50 minutes. I’m trying to decide between upgrading it or selling it and using that money for a Blacktip…

Sure: in the spirit of what @rob.mwpropane was alluding to, you could say something about the use of a nitrox stick with a reciprocating compressor…. (ETA: *oil-lubricated* reciprocating compressor. Of course a Rix is a reciprocating compressor too…. If you’re going to poke fun at somebody about...

And leg mounted dive knife and snorkel! That’s a trainwreck I can’t unsee… Might be time for a update? Maybe slightly more on-topic: I’ve never had e-learning for any technical training, nor was e-learning ever presented as an option. All of my tech training has been in the last decade. But...
