I have for sale two, new in the box, Apeks regulators. Both are DIN. I bought these planning to move into tech diving this summer, but my schedule did not allow for it. The first reg is a XTX50/DS4. The second reg is a XTX40/DS4. The XTX40 as you can see from the picture has never been taken out of the manufacturers sealed packaging. I am asking 475.00 each. Buyer pays shipping, and if using paypal add 3% for fees. The best way to contact me is through email (joe_america@joeyandlori.com).
