While on my last outing here is where my shooting line got tangled in between the grooves on the clips that hold the end of the tendon on the fins. In reality i think they do not serve any purpose except cover the 1/2 inch space.
I had shot a fish at the end of my air, the shaft got stuck on a rock as i made my shot pointing down. as i slowly ascend for air i notice something holding me to the bottom. i try to undo it from the clip, after a few seconds i realize it is not coming off. i take the fin off and ascend quickly, it was not easy finning up to the surface with one fin. it almost felt like having no fins. i thought of ditching my weight belt and decided not to.
