monofin builder
You can buy good handmade mono's from Sebak Estonia.
Their web page is
www.sebakfins.com .
The Sebak personnel cannot answer, which kind of monofin is good for
freediving, because their primary customers are finswimmers.
I bought a monofin from Sebak in 6/2000, and I am very happy with it, I
use this monofin in freediving-pool sessions and after couple of weeks I
maybe have some knowledge, is it good in open water constant weight
diving. Also I cannot answer, which kind of monofin is good for
freediving, but I hope some other guy have opinion about the issue
(would a wider be better, or longer). In Sebak they have very many
stiffnesses of the blade material. Their standard blade size is about
70cm x 70cm, but you can order whatever size you like.
