I’m a bit disappointed with the overall layout of the digital material. Some of the pages are cluttered and difficult to navigate, which made it hard for me to focus on the content. Still a great resource, but not perfect.

Raj Singh –
Does this upgrade make sense for a recreational diver like myself?
Junhao Lo –
Thank you for reaching out to us about your concern, Raj. This upgrade is perfect for any diver, regardless of their level of experience. The Extended Range (ER) and Extended Range Nitrox (ERN) certification allows you to safely dive to greater depths and extends your dive time. However, if you’re just a recreational diver, we recommend exploring other options like the Specialties Upgrade Package. It’s designed specifically for beginners and experienced divers alike, and provides a more comprehensive training experience. Would you like to learn more about it?
Kevin Wong –
What’s the difference between this upgrade and the standard Extended Range material?
Junhao Lo –
Thank you for reaching out, Kevin. The key difference between the Extended Range – Extended Nitrox upgrade and the standard Extended Range material is the inclusion of special considerations for diving with nitrous oxide. The Extended Nitrox upgrade provides a more comprehensive guide for safe diving practices when using nitrox, which can extend a diver’s no-decompression limits.
