I am looking for Recommendation for a new primary light. I wand a very bright light with ability to focus beam from narrow to broad. So far most of the high power lights I have looked at are either narrow or broad beam, nothing adjustable. I have lots of 18650 batteries, as my other lights all...

Recient,y completed SDI dive master, thinking about TDI dive master and have two questions. What are the annual fees? Will I have to pay fee for both SDI and TDI or does one fee cover both? Second says that a TDI DM candidate has to repass the highest tech rating. I did extended range by...

A SDI instructor needs to have speciality instructor courses to teach each and every speciality but I cannot find any informationabout the courses. Are they online or just how does one go about becoming certified to teach specialities?

I recently completed TDI AN and DP courses. I came to Moalboal Philippines just before the pandemic and decided to just stay here until it is over. I had been rec diving a few times a week but after a while wanted something a little different. I signed on for the two TDI courses Prior highest...

I had been tying the fisherman's knot to attach my necklace to the regulator. However I quickly lost two of them. Now I just tie a bowline with a small loop on each end of the bungee cord. Each can them fit tightly over the mouthpiece securely holding in place. Given a sharp enough pull, one...

I got a new Perdix this week. ( See my post on most expensive dive regarding flooding old DC lol) It is everything you could want. I am still exploring its capabilities and operation. When opening it there was a card inside warning that alkaline batteries could leak and cause damage. I turned...

I am currently diving with a BC and am considering switching to a BPW set up. I dive warm salt water, no neoprene just board shorts and a rashie. I now use 4.5 kg weight and am thinking of dropping a half kg. I am currently on a fat loss/muscle gain quest and expect that by the time I hit my...

Diving on a limited basis has restarted in Moalboal Cebu province. I had my first dive on Saturday and went again on Sunday. Right now it is only shore dives so with two sites available, left or right, I will spread out my diving to keep it fresh. I am diving with Cebu Dive Centre and the left...

MOLLE stands for Modular Light weight Load carrying Equipment. It is the web straps that you see on a soldier's battle vest that allows different pieces of equipment like holsters, clips, pouches etc to be attached in many different configurations. It is also becoming more common on civilian...

I am of the school of thought that the only specialties to get are those that give you a c card required to do some types of dives that you want to do. Examples are deep, nitrox, ice, cave and wreck dives. You are likely to be asked to show your card at a reputable dive operator to do these...

I am considering switching to a BP/w set up. Currently I have a traditional jacket style BC with integrated weight pockets. I carry 10 lbs. weight without my shorty and 12 lbs. with it on. This is about as close to optimal weight as I can get. I mostly dive warm tropical salt waters. Now...

We have all seen some pretty innovative dive shop logos. My favourite is Cebu Dive Center in Moalboal.

While the actual decree said shutdown at midnight tonight, (Monday 23 Mar midnight local time) the police came by and shut down diving today. I had planned to do three shore dives but was on my first surface interval when the diving was canceled. Only one training dive, to finish off a group...

I was reading about the incident in Bali that occurred a couple years ago where some divers were separated from their boat and wee on the surface overnight in high seas. Some divers were separated from the group and were lost. I made this little rig to prevent that from happening. Hook the...

Does diving training as practiced promote Dunning Kruger? For those who don’t know the Dunning Kruger effect it is the tendency of people who know a little about something assuming that they know it all because they do not know what they don’t know. They overrate their skills and ability...

I am OK with buying the stuff that involves life support or is integral to the dive manufactured by the name brand scuba dive manufacturers, reg, mask, fins BD etc but I do not see the reasons for buying scuba manufacturer branded stuff for other equipment. For example there is a thread on tech...

I am a Canadian citizen but am considered a non resident of Canada for tax purposes. According to the DAN website coverage is only available for residents. What criteria does DAN use to determine if I am a resident or not. I still have a valid Canada driver license? Does that qualify...

Can anyone explain why dive computers will force a 24 hour wait to switch to air after diving Nitrox? I only use Nitrox on multiple dive days, 3 or more in a day. The next day my Aqua Lung i330c will not allow me to switch back to air but will allow a 21% Nitrox mixture. If I use Nitrox one...

I would like to find a portable gas analyzer. One that will allow me to test for O2, CO2and CO in tanks before I dive. I am in the Philippines and lets just say that sometimes quality control here is not as good as it could be. I have seen 40 Nitrox tanks lined up but we could not dive with...

Do they still ice dive there in the spring time? I was diving with Diver's Den there and got my ice certification in 97. I saw my last time in Winnipeg that they were closed. What is the dive scene like in Manitoba now?
