Bism Regulator Titanium Platinum Nereus RX3000PT Titanium for both 1st and 2nd stages The unique swing head reduces the feeling of being pulled when turning around. It is a high-spec regulator with a flow control mechanism. Please check the manufacturer's website for other detailed specifications. Bism Octopus SS2600KKK-1 Bism Gauge GK2410-3 Accessories include a regulator bag, blank nut, and product warranty (expired). The bag has not been taken outdoors, so it is in a clean condition. There is slight free flow on the 2nd stage side. Please have it overhauled for safety reasons. Bism regulators seem to have fragile internal seats, and although they have been improved over the years, they seem prone to free flow. The hoses are very soft, as you would expect from a rubber manufacturer. The synergistic effect with the swing head made the unpleasant pulling sensation less noticeable. The hoses still seem usable, but please check them during the overhaul. Used approximately 80 times. Purchased in December 2012, but has been stored for a long time due to lack of use since the COVID-19 pandemic. ※Correction※ After reviewing images and logbooks, the last date of use was November 2023. I have checked the operation with my own tank. Apart from the regulator's free flow, it was breathing properly, and there was no strange needle fluctuation on the gauge. I am also selling other diving equipment and a very rare and hard-to-find S-Pro BC. Discounts available for combined purchases. Thank you for viewing. I have added an image of the pressure gauge connected to the inflator hose. The pressure gauge, tank, and BC are not included.
