NOBODY MAKES GOLF CLUBS THE WAY WE DO. PERIOD.

We started with a unique design. With the help of a world-renowned metals expert and utilizing an extremely complex manufacturing process, we integrated the most exotic, high-performance alloys. Then, we refined our design again and again with an intense focus on maximizing performance and feel.

Sound expensive? You bet. Worth it? Absolutely.

The difference is noticeable.

Designed by golfers, engineers and dreamers with an unrelenting commitment to create the absolute finest golf equipment in the world. They feel better, out-perform other clubs, and inspire confidence with their sleek eye-catching design.

For the select few who have the means and the desire to play golf with the very best, PXG clubs will soon be available.

the story

we all agree that to make more putts, it’s critical to keep your eye on the ball, yet the elaborate shapes, reflective metal or white finishes of most putters encourage the opposite.

Mantis makes the ball the hero – simple as that. The patented design has been proven to show that when putting with the Mantis, your eyes stay on the ball, not the club.

the problem

we all agree you have to watch the ball, but most putters steal the spotlight. They often have elaborate shapes, bold design elements or stark white finishes. All of these fight the ball for attention. The putter is part of the show, but the ball is the hero.

Too Dark
Too Light
Too Shiny
Just right

the solution

The design elements of the Mantis putter combine to instill confidence, facilitating a golfer’s ability to watch the ball, not the putter – leading to greater focus, concentration and putting results. The organic design of the Mantis eliminates distracting severe geometry, and the putter’s muted green turf-like color allows its exterior to blend with the putting surface. The high MOI (moment of inertia) of the Mantis means it will twist less on a mis-hit, thus minimizing the effects of a mis-hit as the ball tracks toward the hole. The face-balanced design provides a quality of solid balance, and the soft polymer face and optimized head weight feel perfect.

Low Tide

In the spring of 2012 while on the golf course, we had the idea to design our own custom putters. We knew that there are a several products out there, but we wanted something more personal. Something which could not be purchased off the rack at your local golf store. Something that you would want to pass down to your family. Something that had meaning behind every putt that you hit. Fortunately for the two of us, we had the knowhow and the resources to make it happen. Between the two of us, we have over 10 years of design experience and another 12 years of machining and CAD experience. We decided to come up with a plan to make our vision become a reality.

We met several times (on and off the golf course) to discuss what we liked and what we didn’t about what was currently available in the market. We sketched out some ideas on paper and created 3D models of what the finished products could potentially look like. After countless hours of sketching and molding, and even more time programing and drawing in CAD, we decided to take our designs to the workshop.

Our goal was simple, yet precise: we wanted to make custom putters that looked good and felt amazing. When it comes to design, we believe that less is more and the least amount of disruption and visual noise the better. We wanted the lines to flow and the alignment to form a clear path from the back of the putter head, straight into the top line of the putter and right through the ball to the hole.

On a foggy Carolina Friday night in early August (after our day jobs), we went home for a quick dinner with our families, put the kids to bed and arrived at the workshop around 9pm. It was time to go to work. After about 9 hours of milling, grinding, calculating, sanding, drinking numerous cups of coffee, blasting, reviewing, troubleshooting, and more coffee we both had reached our limit for the night. We left the workshop around 6am with the sun rising in the distance to go back to our homes and get some rest. We both caught quick naps but were soon texting back and forth, figuring out how to convince our wives to let us go back to the shop and finish what we had started. The process of seeing a sketch start on paper, be molded by hand, transferred to a computer, and finally holding the finished working putter in our hands was a feeling that we will never forget. It truly was magical.

On behalf of both of us, I’d like to thank our beautiful wives and our families for not thinking (or at least telling us that) we were completely crazy for doing this. If you’re interested in our putters we’d love to hear from you. Drop us a line or give us a call.

Bombtech Golf

Driver Design ProcessAs told by University of Vermont Engineering students

WWW.Bombtechgolf.com

 

We began by creating a problem statement to give our team a focused goal of what a successful design consisted of for this project and to provide guidance.

The problem statement: BombTech Golf wants a radically new golf driver head to be sold to the public. The driver head must adhere to USGA standards and must not infringe on any existing patents. It should have a loft of 10.5 degrees, be compatible with common shaft sizes and should be designed with the average golfers’ ability in mind. Wind-tunnel testing and CFD modeling should prove that this new head is aerodynamic while offering a large sweet spot. The driver head design will be manufactured out of a Ti-1188 titanium. Samples will be tested to provide physical data as well as user tested and graded to insure that a high quality club has been created.

Generating Ideas

To gain some general ideas and a starting point we researched patents and prior art for “aerodynamic” woods that had already been designed. This led us to club heads with dimples, channels, and grooves. We realized that a club head with a feature that reduced drag such as a cavity, such as these patents, would be more innovative and visually appealing than simply creating the most sleek club head possible.

We researched cars, boats, and trucks to see how they tried be more aerodynamic. We found our answer with trucks. A truck, like a golf club, has a large front surface that increases drag and cannot be streamlined like a small sports car. Everyone has heard the myth that you get better gas mileage with your tailgate up. This has been proven by different entities, most popularly Mythbusters. The tailgate creates a pocket of air to form in the bed of the truck which lets the oncoming air to travel over it instead of diving into the bed of the truck creating drag. We believed we could do something similar with a golf club head by making cavities in the sole of the club.

It was decided that two cavities was best to keep the center of mass directly behind the center of the club face. We created a 3-D model of a club head in SolidWorks, a Computer Aided Drafting (CAD) program. In this program we were able to use a Computational Fluid Dynamics (CFD) simulation to test different shaped cavities. We performed some simplified calculations to get a rough number for what our drag force should equal to prove the CFD models were accurate. We then began running dozens of tests to find which shape, depth, and angles of the triangles created the least amount of drag.

The Numbers

In order to make certain that our CDF simulations were accurate we analyzed the drag force on the club using the following equation:

The density of air is known. The drag coefficient is based on a geometrical assumption and therefore also a known constant of 1.17. Since the density of air and the drag coefficient are intrinsically predetermined, we wanted to be very precise with the projected area. Using the maximum allowable face dimensions, we arrived at an area of 0.0070939047m2. It is important to have this many decimal places, as it is a multiplier of the entire equation. We also decided on a club velocity of an average amateur golfer (85mph). This is an arbitrary number as long as we use this value for all testing, both physical and computational.

Fd = 7.21N This value served two purposes. It gave us a reference number allowing us to be certain that our simulations were accurate. 7.21 Newtons also served as a target maximum. Since the projected area was exaggerated our drag values at 85mph should fall below this mark. We were pleased when our simulations of our most aerodynamic design (now the GRENADE) was returning drag values of just above 5 N, well below our calculated maximum of 7.21 N
