It wouldn’t be a list of the best regulators without an Apeks or two (or three). The XTX40 is one of the company’s affordable models. Despite the very tempting price point, it’s more often viewed as a high-end product.
Loved by techies for their reliable deco reg performance and by recreational divers alike, the XTX40 offers a lot of bang for your buck.
Things we like:
Good for cold water diving
Balanced and environmentally sealed.
Braided flexihose comes as standard.
Exceptional breathability for the price.
Suitable for mixed gas diving and 100% O2 after being O2 cleaned.
Things we don't like:
There’s really not a lot to criticize here but if we’re really being tough we could point to the o-ring in the swiveling first stage. Because of the design, after a few years, you may see some tiny bubbles escaping from the join point.
