My name is Neven Grubelic I am Croatian and I live in Zadar a few meters from the Adriatic sea. I've been making spearguns since 10 years (2010). When you talk about roller, i'am the guy who's been working on it since a long time ;).. I design my first roller in 2012 and it's already an invert..
The story began with the design of two classic spraguns for my son. My expertise as an automation engineer and my passion for spearfishing has allowed me to design excellent spearguns. The performance of invert roller has led me since 2012 to work on this type of design but I still design classic spearguns at the request of my customers.
