I have two of these and using them as singles they are the perfect size and weight for beach dives. More than enough air for one dive, sometimes two. Being steel and smaller they displace less water so you need less lead, for me just 3 pounds with a 3 mil suit.
Since I breath like a girl I can use these for some boat dives also.
IF anyone from NJ/Pa. wants these make payment arrangments with him, I’ll pick them up in FL and bring them home, Ray
