What’s the one call that never gets left?

[g8rvet]

If I ditch my vest and am only pocket carrying like I do late in the day or when warm sometimes, I always grab:
HS Strut Triple glass
HS Strut Raspy Old hen

I don't think those are the best, just that I have used them and called in so many birds I have confidence in how I can make them sound. Both are simple and effective.

If it is a rainy day, I leave the Triple Glass and carry my Yingling Wet Dry glass call.

I always have a mouth call in my shirt pocket and a Lonnie Mabry aluminum pot that sings

River cane in the south, Pinhoti grey ghost anywhere else.
