Hello all.
I've read lots of chatter on various forums about the spear gun shaft speeds and the such.
But I've seen very little dialog about the sound of the gun and it's impact on the target fish.
From what I've read a typical shaft goes from 25 - 29 m/sec ( ~ 60 mph) so it's humming along. But the speed of sound in water is much faster than in air. Typically 1,550 m/sec not accounting for water temp.
So anyway, Is a the noise of the gun a factor? Are some more noise dampened than others? Is this considered in the design phase?
I read about getting faster shafts and U-tube videos on fish dodging, Matrix effect, but seems to me the sound is the warning vs the other stuff.
Perhaps I'm all wet on the topic. Love to hear what you guys think.
