Hey here's my first experience with the Trigger by Black Fox fishing.  Played around with it a bit on the ice and ran into a couple issues.  One being you need a rod with big enough eyelets to fit on the trigger release.  You should also have the river buried in snow and ice so it doesn't get taken down the hole.  I did end up catching some pike on it so it works, but just a few concerns I describe in the video to be aware of if you plan on using one of these devices out on the ice!  They are made in Canada and if you feel the Jaw Jackers are too expensive this may work for you.  Personally I still like the Jaw Jackers.  Anyways if you were planning on purchasing one check this one.
