Stick to one technique while you're looking for that first hook-up. If you're losing gear, then pick a cheap technique (halibuthitman has that covered for you!).
Wear polarized lens (aka magic fish glasses), I like Cocoons worn over my prescription lens. Do get black frames, don't get turtleshell frames. Fish where you might actually see passing fish (shady, shallow, narrow upstream end of a pool with good cover on a smaller river with clearish water). Arrive at dawn and stay there until dusk. Wear clothing that blends in (no need to go camo) and don't sillouette yourself against the sky and keep your shadow out of the water. Don't let your dog or children go splashing around. Cast infrequently and spend time observing. Eventually you will see a fish, hopefully in time to target it; otherwise, sometimes the magic happens and the fish hooks you before you see it.
I've been a trout angler most of my 53 years. The first time I went to a winter steelhead stream, in 2008, I had a big fish lunge at my wobbler, but it totally missed and there was no repeat. We were just messing around because we needed an excuse to check on the cutthroat population, yet seeing that I could get a reaction had me hooked! I poked and prodded at steelhead each winter, but didn't catch anything until 2012. And then winter steelhead fishing turned into winter steelhead catching, where I could purposely target fish and get results. Steelhead are just big trout; they're blindered slightly by that spawning mission, but they really do have all normal trout habits. This year I've had the mindblowing experience of scanning a rain-swollen, nearly blown out river and saying, "if I were a steelhead, I'd be there", pointing and then seeing a steelhead come through the murk to the surface exactly at that moment!
