Using a Transmitter? August 16, 2019
If you have a wireless air-integrated computer, the transmitter, jutting out from the side of the regulatorís first stage, can look seductively like a tank handle to uninitiated boat crews, and they may grab it. Mounting it at the end of a short (six-inch) high-pressure hose avoids costly errors, but donít also forget to install the little double-ended flow restrictor supplied with your computerís transmitter, rather than the single-ended one for use when fitted directly to the first stage.
Dive Rite Recalls Its Low-Pressure Regulator Hoses August 16, 2019
The hoses, in lengths between six and 84 inches, were sold between February 2018 and July 2019, either individually or as part of a regulator or rebreather package. Theyíre suspected of not meeting design and performance standards. The specific hose assemblies recalled are marked with the codes of: 0308, 0388, 0598, 0808, 1648, 1738, and 1998 Ė look for the coding on the ferrule or hose itself. Return your recalled hose to the dealer from which you bought it for a replacement. More recall details are here.

Amos Nachoumís A Picture of His Life August 16, 2019
Some of you know Amos from his underwater photographs of large marine life, from humpback whales at the Silver Banks to leopard seals in Antarctica. His greatest ambition has been to photograph a polar bear swimming underwater, surely his most dangerous subject. Although this documentary focuses on meeting that goal, it also delves into how Nachoumís life in Israel, the complex relationship he had with his father, and his military history have led to his quest. See the film trailer here.

How Long Should You Wait to Fly after Diving? August 16, 2019
Itís typically thought that divers should give themselves 24 hours before subjecting their bodies, loaded with nitrogen, to an airplane ride, but not all divers do that. New research shows that even 24 hours may not be enough to prevent decompression illness, especially after a multi-day dive trip. You can read it for free here ...
