I have several of these. Wouldn't have purchased so many if the first one was not up to par. A word of advice though, if your order one, add a couple of air spools as well. As with any SPG, the spool O ring is the weakest link, and at $1:50 apiece, it's much more efficient to just replace the...

Pura Vida Divers is a few hundred yards away from BHB. They are offering a guided night dive on the 19th. Cost is $15.00. They will be able to rent you anything that you need. (Well, maybe not lights so you might want to bring your own.) I've used that shop for years and can recommend their...

I’ve earned more certifications and thus own more C cards than I can count. (Only have 20 fingers and toes.) I’ve scanned or photographed most of them and keep copies in image folders on my phone and laptop, and thus do not need a cell or internet connection to present a specific document. I...

Yaay!! (and there was much rejoicing) In the frozen land of Nador, they were forced to eat Robin’s minstrels.

Of course the simplest course would be to beg, borrow, or steal a tank with the same gas as one of the pair that you’ve already got, or dump the contents of one, and fill it with the same mix as the other.

Hi Mike1967. Please keep in mind that this thread is in the Basic Scuba Discussion forums, and that side mount diving itself is a technical approach that originated in, and is most popularly used amongst the cave diving community. (Though in recent years it is gaining some practitioners who...

I fail to see the logic behind your overall strategy, and suggest that you seek training in decompression procedures and the protocols for switching from one breathing mixture to another prior to attempting to execute the plan that you propose. Were you to attempt to proceed with your plan to...

Welcome back scubadada. Sorry that the diving in Cayman did not meet your expectations. I presume that the Aggressor did not make the crossing to Little Cayman, because that usually results in a group of happy divers. I don’t recall if you are interested in diving beyond recreational limits...

While the vast majority of my friends who regularly participate in blackwater dives offered by a few local commercial dive operators are very enthusiastic photographers or videographers, it is not uncommon for divers with no desire to make images to join these charters for a few trips. Most of...

I took the IAND class in July of 1991 with Dick Rutkowski, the man who literally wrote the book on civilian Nitrox diving following his retirement from NOAA. The classroom session lasted about 4 hours, covered all the necessary bases regarding math, physics, tables, and physiology, and was...

I had never considered the Perdix to be a “recreational” computer, and thus did not even know that there was a separate Rec Mode manual until you pointed it out scubadada. I downloaded it and just read the relevant data on Conservatism. I stand corrected sir. If a moderator can delete my...

Hi Satrekker. I made a quick review of my Perdix manual and the Shearwater folks state that the default of the system is 30/70.

Hi ND5342. As long as this thread has meandered a bit, here’s a further diversion for you. Here on SB there’s a poster with the user name Dsix36. I believe that he’s made stands for several different CCRs in the past. He recently beta tested stands for Megs and Pathfinders and is currently...

Hi tbone. I need a pair of monitors, but prefer a trio with my current configuration and do not wish to use a NERD. I have tailored my ISC CCR to suit my individual preferences, and while I think that the NERD is an elegant system, it interferes with my access to the camera viewfinders that...

Thanks for posting the image of the head and the referral to the FB pages. Seems odd that there are only connections for a controller and HUD or NERD, and not for an alternative secondary computer. While I’m not considering abandoning my ISC rebreather, I’m curious about the new unit, and...

Of all the on-line shops mentioned in this thread the only one I’ve used is Dive Gear Express. I believe very strongly in supporting local businesses, and am fortunate enough to have a very large number of dive shops near my home in South Florida. The service that I’ve received from DGE has...

Sorry OP, but I’ve no experience with the Momentum Torpedo watch. In my 44 years of diving I’ve managed to destroy a pair of Tag-Heuers, one Breitling Colt Ocean Master, and one Casio G-Shock. Most of these provided years of reliable service. Two years ago my wife gave me a Citizen Eco Drive...

Oops. Sorry, but I provided a link to the wrong thread. Following is a link to the thread to which I was referring. BTW, the search function on this website is your friend. Anyone got info on the French Polynesia Master liveaboard, launching 2016?

There is a thread on the fourth page of these listings with reviews of that boat. Last posting was about a year ago. I'll try and post a link to the thread. FRENCH POLYNESIA MASTER LIVEABOARD
