Congratulations on a very nice bird! Sounds like you were very lucky on the recorvery - but your persistence paid off and you are to be congratulated for that.
After reading some of Guru's stuff on using a stringtracker, I started using one - after I lost a big bird with a good hit but just couldn't find it. I've killed one gobbler since then and followed the string about 125 yards to that bird. I wouldn't turkey hunt without it....
