About

 What is PuttRay?

PuttRay is a simple tool for helping you keep your eye on the ball and your body aligned with the hole while you putt!

There are so many expensive tools out there which claim to help you improve your golf game. Having tried several myself, I can say that many only serve to complicate things. PuttRay is a simple, inexpensive tool which helps you polish your putting skills without complex or distracting equipment.

PuttRay is simply a green laser with a special lens embedded in a clip for the bill of your hat. It helps you to keep your eye on the ball and your body in line with the hole.

How Does It Work?

PuttRay is simply a green laser diode embedded in a hat clip. The beam is focused into a line by a cylindrical Powell lens. Its powered by three (3) LR44 button batteries and is activated by a simple on/off switch on the rear of the hat clip. The batteries can power PuttRay for about 90 minutes, long enough for about 10 golf games (assuming 30 seconds per swing).

The laser diode produces a 532nm wavelength beam at 5mW (a bright green beam). We chose green over other colors (like red or blue) for several reasons, but primarily because its easier to see when reflecting off grass.

How Far Along Is It?

We've now made and tested five PuttRays and perfected the design to simplify assembly and maximize performance. We've found vendors for the laser diodes, lenses, and injection molded plastic parts. We've worked out bulk pricing for several different volume levels, and we're ready to begin ordering parts and assembling units. Now we need your help to get up and running! 

As with most products, PuttRay is only economical if its being made in bulk. The parts are too expensive when ordered in small numbers, and we simply can't afford to order the parts in bulk before finding interested users. That's why we're here on Kickstarter! You can help us bring this useful tool to market, and be one of the first people to start benefiting from it!

Risks and challenges

PuttRay is a surprisingly useful tool considering its relative simplicity and low cost. However, a large amount of work went into engineering this tool so it can be used in virtually any kind of environment you might encounter. Regardless of lighting conditions, weather, terrain, or the type of hat you wear, PuttRay will be a useful training aide.

Not surprisingly, the biggest challenge in designing PuttRay was the laser. Although red laser diodes are often smaller, cheaper, and use less power, PuttRay needed a green laser diode so the beam would reflect clearly off grass. After testing nearly a dozen different diodes, we finally settled on one which met our size, weight, and power requirements.

The laser produces a 3mm beam, which is spread into a line by a special type of cylindrical lens, also known as a Powell lens. The line is projected at an 80 degree angle, creating a line over 9 feet long when used by an average height male.

The other difficulty was designing a hat clip which would attach securely to any common hat. We tested several designs on several types of hats, making changes as necessary. Our final version attached reliably to any type or size of hat, and remained simple enough to manufacture as one solid piece of injection molded plastic.
