Neovollic Doubling Set by Neil Kalmanson Price: $41 /pair ; Availability: 1 RH set

---

This doubling set was made out of Birch plywood. Similar in size and performance to plywood two bladed doublers of the mid 1980s, but with clever artistic shapes. The two boomerangs also interlock together like puzzle pieces and you can throw them individually as sport boomerangs. Some wear, but still in very good to excellent condition. Signed and dated 1986. A wonderful piece of artistic expression from the golden era in American boomeranging. Span = 41 cm ; weight = 174 gm (pair)

"Space Doublers" by Günter Möller Price: $52/pair ; Availability: 6 RH + 1 LH

---

This is a pair of tri-bladers used in the doubling event. Made out of 2mm phenolic paper (PERTINAX). For advanced throwers only. Instructions are included. This model requires a harder throw than most doublers, but it has better wind resistance as well. Flight distance (weighted) = 24-26 and 27-30m. Thrown at the same time, they separate and return on different flight paths to the thrower. This enables the thrower to catch the Inner Space first and the Outer Space second. This is the technology that Gunter uses when he competes in World Cups! These come in a variety of colors - my choice of colors please. Radius = 14 cm ; Weight = 85 gm (pair)

Blue*Star G12 Doubling Tri-bladers from Volker Behrens' Throwkit Price: $734/pair ; Availability: 1 RH

---

This set of slightly used Doublers is from Volker's personal throwkit. It is an advanced set of competition boomerangs made out of G12 material. Brightly painted and heavier than the standard Paxolin model, these have better wind resistance and Volker claims that they are nearly unbreakable. The tri-blader with weights and 3 small holes in the hub flies higher and it comes down more quickly. The other tri-blader stays in the air several seconds longer allowing you to catch both with plenty of time to spare. Radius = 15 cm ; weight = 100 gm
