I just got my tagger and tags last week. I have tagged around 20 bass so far and it is really easy to do. I haven't seen any problems with them after tagging what so ever. I tagged 11 satuday morning and went back that afternoon and actually caught 2 that I had tagged that morning. I ordered mine from Greg Grimes at lakework.com the gun and 100 tags was like $130.00 plus shipping. It took a little practice to get the hang of it but after the first couple of fish it was simple. Read the thread on tagging 101 it explains it pretty well. Good luck!
