It’s a question any devoted angler has pondered: What does my fly look like to a fish? 

Thanks to the wonders of technology (GoPros, namely), we can now see from an underwater vantage how our patterns appear to fish and how they react to them; we’ve provided two videos that capture trout from beneath the surface.  


This first clip shows golden trout making repeated strikes at a passing nymph. Keep your eyes on the orange strike indicator: The fish seem wary of it being so near the fly and none commit for a full bite—surely a stunning revelation for this unfortunate angler.   


This clip provides an even closer look at trout cruising the current. While the fish don’t strike a fly, it’s neat to witness them perusing for food from such proximity.
