Hi Guys, as you can see form my other thread, I bought the aquatic magic regulator but now its arrived i can see its very different to my JBL one and not too sure if its right! Here's an image: You can see here that there is no 'o' ring and the only seal is a hard plastic ring that sits flush with the edge. MY JBL has an 'o' ring on the metla insert to create the seal. You can see a comparison of the too here: Aquatic Magic JBL Also, the bobble counter sits horizontal when the dials are upright. Only way to get the bobble counter to work would be to have the dials lying flat as shown here: Can anyone confirm if i have been sent a dodgy regulator?? I know Dan has one of these as well as others so hopefully you can help.
