I disagree that I am missing the point, but I suppose that is dependant on what you think the point is. Since the marine park will be paying for the tools, it seems only reasonable that they should get to decide what those tools will be. Let's give them the benefit of the doubt, that they have done some research and made an informed decision. It may not be the decision that everyone else would have made, but it was their decision to make. Let me restate that; it is THEIR decision to make.
Let me be a little more clear and concise about what I and I believe many others feel the point is. (See first post) I feel money could be much better spent on spears other than the ELT, that cost 1/4 or less and are just as effective, if not more so at a distance and with larger lionfish. I have no problem with non-DM's and approved divers not being allowed to spear in the marine park.
As for it being the marine park's decision, that is true, but they apparently are NOT paying for this on their own, or we wouldn't be talking about a fund raiser.
You can give them the benefit of the doubt all you want but I question the decision process in going with the ELT, and anyone who might want to donate to the cause has every right to do so. We are talking about Mexico, after all... And anyone that has lived there, not to mention done business, knows how these things go..
