Used B2 sets. I was told these were serviced 4 years ago and then have been in storage. Dove with both of these at 35' in fresh water and they breathed well. The red 2cnd has a small mouthpiece on it. The SS1 hoses attached are not included unless you want the SS1 for an extra $100 each. $300.00 per set plus shipping. Mares SPG's "BAR" incuded. The SPG on the grey B2 was bubbling a little after the dive when held at certain positions.
