Yes, technology is great--when it works. I have just this week acquired two devices that, so far, work wonderfully well. One is the Crimson Trace laser grip, and the other is a Bear compound bow.
After much thought, I finally decided I didn't need yet another snubby revolver at home in the safe, in this case the Ruger SP101, so I decided to sell it and use the proceeds to pay for laser grips for my S&W 642 snubby. According to my reasoning this gun is almost always with me and, given its limited round count, I need to maximize my potential for hits should I ever--God forbid--need to use it to defend me or mine. I got the LG-405 grip because it has padding for the backstrap of the frame. Usually, after only a few rounds, the web of my hand smarts after firing the gun, but with the CT grip I fired 20 rounds with no aftereffect.
The first five rounds from the gun with the laser installed were astoundingly accurate. I fired them at 6.67 yards (I forgot my measuring tape and had to step-off the distance, which I later measured at home) and had all five holes touching (see below). 'Twas truly amazing.
The other device I purchased this week was a Bear "Charge" compound bow, financed via the sale of two traditional bows. I was thunderstruck by how easy it is to make accurate hits at 20 and 30 yards with the bow, and I'll need this accuracy if I pull my archery deer tag this year (fingers firmly crossed). It's no wonder the compound bow has become the dominant force in archery. As much as I enjoyed shooting my long bow and recurve bow, I'll never go back to either type. Chalk up another one for technology.
I'll be the first one to step up and say that a lot of products on the market that purport to be quantum leaps usually only make things more complicated without much benefit. That is not, however, always true, as the two products above attest.
P.S. None of the companies mentioned in this post gave me any form of compensation.
