Dated 04/16- out of hydro 15 year lifespan has been lifted for carbon fiber tanks if they are in good condition, this one has plenty more life in it! Local dive shop increase the price for hydro testing to $50, so I'm just looking to sell, hopefully you have a place that charges less. I have two of these available (listed separately), perfect for dual tank setups! Will ship empty. I'm not interested in any trades besides what I have listed in my profile description. I will not part out.
