Spear gun advice please.

[gofastsandman]

Just found out one of my a team crew has had an electric Hookah in his garage for years.......Coulda` been buggin`

2 lines @ 100 ft ea.

Now I want a spear gun for grouper `n such.

I understand that Mahogany is preferred because of neutral buoyancy and sound deadening. Correct me if you sea any errors in my thinking.

Two bands are better than one?

JBL make a good product?
