Design by Marco Pisello - an established architect who lives and works in Carate Brianza outside of Milan. A spearfishing enthusiast who between the 80's and 90's took part in several 1st category (major league vs minors for spearfishing basically in Italy) winning many trophies.

Production: limited to 200 pieces for 2005

Design Process – Marco Pisello teamed up with the technical department at Omer to make the architectural drawings (of his early prototype which he commissioned to Omer) CNC friendly through the use of CAD 3D and 4D design software used in Omer's technical department.

Barrel Manufacturing process: Outsourced to an established high end Italian manufacturer specializing in wood. The manufacturer disposes of CNC machines for the manufacturing process while producing these M.Pisello/Omer Master America design. The initial year the Master America debuted in the European market 2003 ½) the 500 piece production was sold out and a rerun especially catered to the necessities and differences of the US and Oceanic markets was considered using Teak wood. CNC machining allows consistencies in precision from piece to piece and the ability to make curved cuts and the milling in the stock that cannot be replicated by typical routers, tables saws etc and can usually only be done by hand by experienced wood craftsman.

Wood: Teak, Burmese teak to be precise. Teak is synonymous with the best wood for marine applications in that it does not require a stain or sealer for protection thanks to its natural siliceous (high silicone) content.

Burmese teak is hard to differentiate from other lesser types of teak like Indonesian teak but as a rule of thumb it is a rich golden brown heart wood while the soap wood is pale yellow. The Master America barrels are laminated using 6 laminations to ensure rigidity and eliminating any possibility of warping and glued together specifically. But more importantly 6 laminations are used because Teak has a natural variation in density of roughly 25-30%, basically not all teak is homogeneous, and therefore one piece may weigh up to 30% more or less than an identical sized piece.

These inherent differences in the wood were considerations that couldn’t be blown off for the proper balance of the gun and therefore all the strips of teak used are weighed so that they conform to a specific weight criterion and the ones that fall outside of this criteria aren’t used.

The Barrel Design takes the classic cuttlefish Master shape with integrated wings which enhances lateral tracking and indentions in the teak are made to snug the fittings for the muzzle to anchor it securely. The hole for the second band is also grooved nicely to conceal the band and integrate it nicely in the barrel once loaded. This barrel shape is a proven design from former Master models and in the Master America version is beefier to increase the mass for the use of two bands compared to previous models that were designed around one band.

Components: The muzzle is another unique innovation in as far as muzzle designs go in that it accommodates the typical screw in strait pull bands that keep the bands in line with the shaft as well as leaving it an open muzzle so that any style of sharkfin shaft or thicker shaft can be used and of course providing a clear line of sight down to the tip. Constructed from solid stainless and anchored through to the bottom with a line anchor using SS hex key bolts and injection molded plastic gaskets between wood and metal.

The handle is the T-20 with three modifications from the standard T-20 handles on our other models:

• A bigger removable butt pad to accommodate loading of multiple bands.
  
  
• Stainless steel line release rather than the standard T-20 to accommodate two wraps or more of heavy monofilament shooting line.
  
  
• Line anchor loop in the front to make rigging of the shooting line more efficient and faster.

Shafts & bands* – The Master America gives the owner the choice of three shaft and power configurations:

90-115cm guns are set up for either use of single 18mm Power band with 17/64” (6.75mm) low profile sharkfin shafts or two power 18mm bands with a 9/32” (7mm) x 63” shaft for the 115cm.

The 130cm version is available with a 9/32”(7mm) and two 18mm Power bands, or three 18mm power bands with a 5/16”(8mm) shaft and sharkfins on the 130cm with break away slip tip.

*All configurations are suitable for the balance of the gun and give a lot of versatility depending on the divers preference.
