The Apeks CTX50 system is especially known for high performance and ease of breathability in colder waters. This entire system was last serviced in August 2014 by Airtech Scuba of Raleigh, NC (paperwork is included in sale), and used only for one 5 day dive trip after that.The CTX50 first stage was overhauled and put into top condition at that time. The octopus was fine-tuned, given new rings, etc. And approved for use at that time, but was not needed on the dive trip. The octopus has rarely been used at any time. First stage dust cap and five connector caps are included. The original owner's manuals for the Apeks (English only) and Sporasub (multi-language) are included. Routine annual service of all equipment is recommended before first use. NOTE: This sale item is included in a scuba gear 20% discount bundle.
