You clearly do not understand how things are and work.
You clearly have watched too many movies and believe they portray
the ability of a speargun out of water.. they dont
And I was being serious.
You can watch videos of guys spear gunning on land. A recent one showed the projectile fly right thru a block of ballistic gel. But sure I also saw one guy who did it wrong and he got hurt. You need the right sort of speargun, and have some practice. Thats how it 'works'with all weapons.
Again you show your ignorance
The skin/hide of a bear isn't ballistic gel.
I have been spearfishing for 30 years .. all over the world.
I believe at last count I personally own 8 spear guns.
You asked for people with ACTUAL first had knowledge.
You have to KILL a determined pissed off bear, neither a flare gun (worthless) or ANY spear gun will kill a 1000#+ polar bear.
How about you answer all the other members here about your ACTUAL BOATING EXPERIENCE?
