In this week’s How to Tie video feature, Gilbert Rowley shows us how to tie the Tungsten Surveyor nymph.

Learn About This Fly

Difficulty: Novice 

The Tungsten surveyor is a variation of the surveyor nymph, a fly that has seen itself in the spotlight recently due to its simplicity, and high success rates. Brought to life by competitive fly fisherman and fly tyer, Lance Egan, this fly has been making an appearance in every nymphing angler’s fly box.

This fly, commonly associated with the Czech nymphing style, is incredibly versatile when it comes to its success rates in different environments. What makes this fly so special is its ability to sink fast and stand out. The mission of this fly, unlike the “Match the Hatch” approach, is to attract fish and encourage them to take a quick swipe. Considering this little guy will easily glide through the current, fish usually only have just a few seconds to act, and will often times meet provocation with action.

If you’re looking for a fly that only takes a few minutes to make, this is one of your best options. Within a half-hour of focused tying, you can build yourself an impressive arsenal of highly effective nymphs. The surveyor pattern, like many others, benefits with a variation. Try different dubbing or different threading in order to explore which color combo suits your area best.
