Transmitter Hose

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.

Pedophile Island  August 16, 2019

In the waters near now-deceased Jeffrey Epsteinís private St. Thomas retreat in the Virgin Islands, thereís some decent diving, but when guides took scuba divers to spots near Epsteinís Little St. James Island, security guards would immediately walk to the waterís edge. ďEverybody called it ĎPedophile Island,íĒ says Kevin Goodrich, who runs Alternate Attitude boat charters out of St. Thomas. ďItís our dark corner.Ē On August 12, the FBI raided Pedophile Island to probe further into Epsteinís alleged sex trafficking ring.

The dwarf minke whales turned up as promised, the reef sharks put on a show, the giant potato cod posed for photos, but our undercover contributor had a rather colorless experience while diving at Osprey Reef with the Spirit of Freedom Ė and the liveaboardís cramped conditions didnít help matters.

Have You Been on a Photography-Instruction Dive Trip?  August 16, 2019

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 ...
