The lost reg

In 2016, a diver had to ditch his rig during a drift dive in Norway. Three years later he found it again. 

The cold Norwegian ocean had claimed much of the kit for herself and was beyond repair. However, the diver noticed that his Apeks regulators were still pressurised and his cylinder still contained air. Despite the cold, fast currents, the debris, salt water and the sea life, they hadn’t free-flowed or leaked. They were fully functioning and just in need of a good clean. 

After three years, his XTX50 was ready for someone to take another breath. 

When we heard about the story, we knew we wanted to get our hands on the regulators and test them in our workshop to find out what the ultimate salt-water test does to the performance of one of our regulators. 


Speaking from his home in Norway, Per told us, “I participated in a border dive in 2016, passing underneath the old Svinesund bridge in Norway and through into Sweden. The straight between Norway and Sweden is at its narrowest here and there is a very strong tidal current and the visibility is extremely poor, maybe 1-2 metres. That time I got into trouble under water and a chain of events led to me dumping most of my rig to stay afloat. I was quite sure somebody else would find the gear, after all there were 10-15 divers in the water. Unfortunately, due to the strong current and low visibility, no one was able to find it.” 

“I again joined the border dive again this year and what do you know, I swam directly into my old gear at 25 metres depth. What a strange feeling to see the old equipment in this murky water. Some crabs had used my gear as a home. After some time we were able to lift my rig to the surface.” 

When we received the regulators from Per, our first task was to empty out the crab shells, stones, sea life and sand that had accumulated inside the regs over the three years. Despite the encrustation covering most of the parts, the first stage turret still swivelled smoothly and the second stage adjusters were still fully operational. 

Reassured that the regulators didn’t need any mechanical intervention or immediate servicing, we put them straight onto our ANSTI Machine to simulate a dive to see how they performed underwater. When we realised that their interstage pressure was still at factory settings, it was clear we were in for a good test. We pressurised the chamber to 53 metres and dropped the water temperature down to 3 degrees Celsius. With a breathing rate set to 25 breaths a minute, we stood back and waited to see what would happen. 

Despite everything they had been through, despite three years of lying in salt water, the entire XTX50 stage three set performed at a standard that would pass the EN250A cold water regulation – straight off the seabed. 

Of course, this is not an advert for not properly maintaining and servicing your Apeks regulators, but it is nice to know that when we say you can trust an Apeks regulator, this story shows that you really can.
