Heavy Putter D3-H

Style
The Heavy Putter D3-H is a rear-shafted putter that takes advantage of all the greatest in standard putter technology. This club applies new concepts in weight distribution to the Heavy Putter concept, involving use of the largest muscle groups in the body stabilizing your putting stroke in a way that a standard-weight putter cannot. The H3 is a perimeter-weighted, rear-shaft model with an offset hosel available in righthand models only. Available in both white (stainless steel) and black (black brushed finish) versions, this putter is made in stock lengths 32 to 36 inches and custom lengths beyond that.
Theory
The Heavy Putter is just that, a substantially heavier putter than the conventional putter. The average Heavy Putter is about 750g with a head weight of 400-465g, compared to 350-375g for a conventional putter. Why so heavy? The swinging weight of the Heavy Putter activates the large muscle groups in your arms, legs and back in a way that conventional putters cannot.
Technology
The technology used by Heavy Putter is all about weight distribution. The weight of the putter head is significantly increased and weight is distributed up the shaft into the handle of the club. The effective result is your center of gravity while putting is raised into the middle of your body rather than midway up the shaft, as with a conventional putter. With the Heavy Putter D3-H, weight distribution is focused down the putter shaft and redistributed through the heel of the club and balanced heel to toe. The sweet spot in the center of the club head is maximized through this approach.
Company
The Heavy Putter company put its first putter on the market in 2004 and immediately appealed to the technology-enthusiastic amateur. According to the company's website, it acknowledges that golf equipment technology has focused on driver and golf ball technology as compared to putter technology. Since almost half of the strokes in the average round are taken with the putter, Heavy Putter realized that golf technology should have a serious focus on the flat stick. With that in mind, the Heavy Putter designers developed a new and novel approach to putter design.
Success
While Heavy Putters and Heavy Putter technology has not been overwhelmingly embraced on the PGA Tour, it continues to grow in popularity on the European Tour. More and more European pros are using the Heavy Putter, particularly the H1 model.
