Thank you for viewing. Used less than 5 times, but stored with other equipment for a long period, so there are multiple scratches. Although I believe it works without problems, I haven't confirmed it, so I recommend an overhaul. It has not been used in the mouth. By connecting it as a BC inflator, an octopus is unnecessary, making it convenient for streamlined diving. Also, during the dive, you can easily exhaust the BC by pulling down the corrugated hose. I apologize, but I am not offering a price reduction. Thank you for your understanding. - Brand: TUSA - Color: Black/Blue - Type: Octopus
