“Direct-to-consumer driver sold heavily via email marketing; a single 10.5 loft was typical but exact stock shaft is uncertain.”

The original Grenade is the club that launched BombTech Golf: founder Tyler 'Sully' Sullivan, a University of Vermont grad running a custom-fitting business, partnered with his alma mater's engineering department on a capstone project to design a driver head that could compete with major-brand drivers at roughly half the retail price. It used an unusual two-piece cast titanium build with a TI-1188 beta-titanium face, and two triangular sole channels — developed with SolidWorks CAD and CFD — to cut aerodynamic drag and raise CG for a penetrating, lower-spin flight. Sold direct-to-consumer with Sullivan's personal cell number for support, it became the founding product of a real disruptor brand in a category dominated by major manufacturers.

Documented, independent media attention well beyond a typical budget driver: multi-page GolfWRX forum threads, a Rick Shiels YouTube/Facebook review presented explicitly as a non-sponsored 'REAL review,' and coverage in Practical Golf and Forbes framing BombTech as a genuine direct-to-consumer disruptor that has sold well over 100,000 clubs since 2012-13 with under a 5% return rate — a surprisingly well-regarded budget performer relative to its price and brand recognition, the definition of a sleeper rather than a mass-hyped icon.

Golfers who want major-brand-competitive distance on center contact at a fraction of premium retail price, and who are comfortable with a direct-to-consumer brand and its 60-day return policy rather than a big-name label, are the intended buyer; someone who mishits frequently and needs maximum forgiveness on off-center strikes, or who values pedigree/resale recognition, should look at a mainstream max-forgiveness driver instead.

• Co-designed with the University of Vermont engineering department as a capstone/senior design project by founder Tyler 'Sully' Sullivan.
• Uses an unusual two-piece cast titanium construction (versus the typical four-piece) with a welded TI-1188 beta-titanium face.
• Two triangular channels cut into the sole were engineered using SolidWorks CAD and computational fluid dynamics, reducing sole drag (BombTech's own materials cite up to a 68% drag reduction) to raise CG and reduce spin.
• Originally retailed around $297-$299 direct-to-consumer, roughly half the price of comparable major-brand drivers of the period.
• Reviewed on video by Rick Shiels, explicitly framed as a non-sponsored review, and covered by Forbes as part of BombTech's broader disruptor narrative.
• BombTech has sold over 100,000-180,000 clubs (per company/press figures) since founding, with a company-reported sub-5% return rate.

First released around 2013 as BombTech's founding product (roster lists 2016, but the timeline implied by BombTech's own history and the 2017 Grenade 2 release — stated as launching 'four years' after the original — points to an original launch closer to 2013; this is flagged for review). It predates and set up the Grenade 2 (2017) and Grenade 3.0 (2019) follow-ons, competing on price against Callaway, TaylorMade and Titleist drivers costing two to three times as much; a modern equivalent in market position is a direct-to-consumer challenger brand like Sub 70 or Tour Edge.

Used examples sell cheaply on eBay, commonly in the $50-$90 range depending on shaft, loft and condition, consistent with a budget-positioned driver that never had significant resale/collector premium even when new; BombTech itself also runs a pre-owned Grenade sales channel at reduced pricing.
