I have only done this once in the keys while yellowtailing we noticed some big shadows under the boat that wouldn't hit.. I jumped in to check it out and saw the biggest damn mango Ive ever seen, grabbed my first most incredible gun in the world "Bandito" and chummed some more. The fish gathered round the chum and so did I, nailed the mango only to have the spear not penetrate *sigh*
The method seems to work quite well on the reef, thats for sure, I just don't use it because its messy and a bit of a hassle.
