Bula Matt,
There have been some good posts on the info you requested
on the
www.spearfishing.com.au There is a new railgun which
has just been released from
www.geocities.com/superfrog/home.
html . Also of interest, Rob Allen,himself, has been answering
questions on the spearfishing forum above.
Let me know what you decide as I'm thinking of getting a smaller
railgun myself. I have an Alexander and Collins bluewater now.
Unfortunately, I'm not able to go to a shop and see the product
in person.
