Every now and again I come across SB threads that I can't access because our company filters (McFee/Websense) class them as "malicious". Example: Blocked Site Details: Category: "Malicious Sites" URL...

I'm having trouble recently (only) with certain threads. I use Chrome (updated version) under Win 7. Version 40.0.2214.115 m Example 1: I try to access http://www.scubaboard.com/forums/basic-scuba-discussions/502410-thicker-wetsuit=slower-metabolism=longer-dive.html Gives me Sucuri WebSite...

Over the last 3 years I bought and tried a total of 9 relatively cheap lights off Deal Extreme ( Buy Diving Flashlight at Dealextreme with cheap price - DX ) the cheapest being 10US and the most expensive 45US. The 2 at 10US are great lights but not suitable for diving below 5 or 6m as the water...

First, my 7mm semi dry with across the back dry-suit type zipper is heavy and complicated. Second because I have my DC and compass on my left forearm and my backup watch on my right arm and I have to find somewhere safe to hang them plus on a heaving boat the overall operation starts to get...

Pretty poor translation - just confuses the issue. The key (and scandalous) phrase in the text is "Lo extraño de este caso es el tiempo que pasó el cuerpo del turista en el mar sin que nadie lo subiera a su embarcación, por instrucciones de capitanía de Puerto para que no se metieran en...

Sounds pretty scandalous even for Mexico. If there really is a recording of the Capitanía issuing those instructions someone should be court-martialed!

see pages 3, 4 and 5 of the standard PADI form. https://www.padi.com/scuba-diving/documents/padi-courses/medical-form I've given this to various doctors over the years and they all thought the guidelines are very clear.

In my experience of wreck diving #3 is rarely true. The current is far too strong for the boat to tie on. Most of the wreck diving I've done the boat will pass over the wreck and the DM or an experienced diver will tie on a buoy and a trailing line. Then the boat will steam past and parallel...

Not sure I understand your second comment. Why would I NOT want to take out a relatively cheap (~100USD) policy to cover me in the case of needing medical care in a foreign country (I've recently seen cases ranging from 10.000USD to 200.000USD) or to fly me home in a private jet air ambulance if...

Just a suggestion but all my wrist mounted devices (watches, DCs, compass) had their straps replaced while still new by a Nato (or Zulu) style watch band. The original straps all sit in my junk box at home. This is a much safer arrangement as the band loops through both fixing pins. It's...

Maybe off-topic but I'm really curious why anyone that is retiring would want to spend money on life insurance. I'm coming up to retirement and the days when my demise would have been a financial burden to my family are now past. House is paid off, kids are grown up and launched on their own...

Well as stated above the water is not from your HP source. If the Bourden tube was leaking the glass would probably have blown out of the gauge. So sea water is getting in to the housing. After a while the inside of the housing will start to corrode, including the dial and the rack and pinion...

I understood that from the drawing but it seems that as you rotate the rod it will drive in and out due to the thread and will not be pure rotation on the o-ring. May tend to unseat the o-ring. Plus in practice the run-out of the outside thread will be very close to the o-ring. Threads only end...

I don't much like the idea of the threads. I'd do what most commercial housings do, use a smooth rod with a groove cut in to accept a circlip to keep the rod in place.

I found this extremely doubtful statement (my own opinion) on an Oxygen Therapy site: "Oxygen is fundamental necessity. Humans need oxygen to survive. There is 21 percent oxygen in the air that is all around us. While people with healthy lung function will find that air holds enough oxygen for...

You didn't say if you're filling at night or during the day.

Unfortunately we often need to pay the high local price although whenever we get the opportunity we obviously buy gear while travelling. My wife's DC was bought in Mexico. My current reg set was bought in Bonaire. I have various pieces of gear bought in Miami and other places. Re the Aquaticos...

Yes, Aquaticos is the recommended dive operation in Recife. You don't give your home location but frankly no one that has a possibility to purchase outside Brazil would seriously consider purchasing a DC in Brazil. Import costs here will normally double the offshore price and it would not be...

So 70% more expensive for the set of SP parts. Big difference that then gets accentuated here by the high import costs.

Purely from a non-political diving perspective I'm in two minds about opening up Cuba to US divers. On the one hand some of the good diving locations were really lacking infra-structure - we stopped diving Isla de La Juventud because the infra was deteriorating, lack of weights for weight belts...
