Just a thought on the many wonderful hunting gadgets you see on the TV hunting shows.........
The hunting shows are basically a series of commercials in which the "hunters" are touting the gear they are using. They may be the actual makers of the gear or they may be getting something from the makers to make the product look good. You can make anything look effective with enough takes and clever camera work.
My earlier remark to Greenhorn was a caution to not get caught up in the gadget craze because it may (and I think often does) do more harm than good.
