Realism is "everything" when it comes to assessing this transfer of simulator training to on-course golf performance. Motor learning scientists have shown that the greater the similarity between the simulator and the criterion task the greater the transfer of learning. For instance, putting across a carpeted floor into a cup is not realistic beyond the set-up and stoke itself. Nothing is learned regarding "break" and probably very little with respect to speed (is the speed of your carpet anywhere close to the greens you play on?). Therefore, this practice will transfer very little learning to real-world greens, and is basically a waste for all but beginners still learning set-up, alignment and stroke.

Another common putting simulator includes an Astro-turf "runway" with a few bumps along the way. This is slightly better because it’s slightly more realistic. Still, unless you run into a green with the same arrangement of bumps, transfer of skill from practice will be negligible. The best putting simulator I’ve seen is the Electronic Putting Challenge by GL Technologies. This computerized putting machine features 72 different six-foot puts with a wide variety of breaks and hills. Extraordinary realism means far greater transfer of learning to the real world. For a serious golfer, it’s the only putting simulator worth buying, unless you can put a few real greens in your backyard!

Virtual golfing is the latest rage at some golf shops because you can actually "play" Pebble Beach while in, say, downtown Philadelphia! While these simulators are clearly entertaining, they possess minimal training value due to the fixed stance and lie. Such blocked practice is effective only for a beginner. As a rule, dabble in these "fixed position" simulators for fun, but forget using them regularly for practice.

Like simulators, there are many mechanical aids available that hold the promise of enhancing your performance. Such aids range from a variety straps and braces to gimmicky, non-traditional clubs. As a rule, these devices can improve the performance of your practice by correcting some fundamental error in the swing. However, I must stress that actual transfer of learning from practice to performance is very specific to the similarity of the feel and conditions. Therefore, you’ll need to continue using the mechanical aid in the play setting to maintain the positive benefits it lends to your performance. Do you want to play the rest of your life with such a crutch?

The bottom line--limited use of mechanical aids during the early stages of learning may help develop the kinesthetic sense of position, posture and certain elements of the swing. Also, they can help an experienced golfer unlearn ineffective motor programs that have been grooved in over a long period of time. However, in the end you need to learn to perform a sound swing by yourself and without mechanical aid. This takes focus, determination and lots of practice. Quick fix technology rarely produces lasting results.
