In addition to using the cane to check for potential snags, I use the fishing rod, which is longer, to reach and sweep in the area where I might be back-casting. To check for snags out of reach of my cane in new areas, I usually put a cheap set-up on my rod to test the waters. If there are any snags out there, I lose only the cheap tackle and not the more expensive lures. Besides, I might even get a bass to take the bait while testing. After I have found that the area is mostly snag-free, I switch to more expensive lures.
Sighted fishers lose a lot of tackle, too.
Because modern lines are more supple and finer than in the past, they are harder to feel and thread through the eyes of hooks and swivels. This helps me rig up faster. For smaller hook eyes and finer lines, I also use self-threading needles or fine wire needle threaders. For fine tippets and very small flies, I use a fly- threading tool that I purchased from a mail order supplier for fly fishers. It holds the eye of the fly while I hold the tool and guide the fine leader into the slot that guides the leader through the eye of the fly.
