is the optional Stainless Steel PiggyBack version of the Blast Head unit. It is especially helpful for those who will be blasting in the horizontal or inverted orientations. If you already have a Stainless Steel Blast Head you can find the bolt on PiggyBack Weight in this store under the SierraBlaster Accessories category.
Blast Head is reusable and helps contain the explosion inside the
material to be blasted so that the power is used to split the
material instead of escaping out the borehole. Without the Blast Head
the powerful 375 Magnum Cartridge will not develop to its full potential thus you
have an important symbiotic relationship between the Blast Head and
the 375 Magnum Cartridge. Remember
if purchasing additional blast heads for your system you must also
purchase a Blast Cord for each Blast Head. A Blast Head with the PiggyBack Weight attached will not fit in the standard SierraBlaster System duffle bag.
purchasing more than one Head of any type (Stainless, Aluminum, Stainless PiggyBack) the price is reduced by $45.00 per
Head! This price discount is shown when you add two or more of any Blast Head to the cart. This works with any Blast Head combination. You can mix and match Blast Head types and still get the discount.
