Υπηρεσίες Groupex

In 2018 we decided to create Groupex, an online store fully specialized in underwater hunting. the factors that made us stand out in the market were the knowledge we provided through our experience of many years freediving, spearfishing and actual research and development of our teams spearguns through custom upgrades directly affecting strength, accuracy, and maneuvarability. These types of setups or conversions of conventional spearguns to Invert Rollers- Polyspasts (Demultiplied Spearguns) provide the power and speed and accuracy needed to catch the most difficult prey in the mediterranean ocean with zero recoil. We also setup various accessories bought from our shop such as Diving Buoys, lines, fish stringers, etc. Today having hundreds of loyal customers who trust us and have supported our company we have tripled our dynamics and can ship very fast to the destination given.

Now, having dozens of happy Spearos, we have tripled our potential and can ship immediately and quickly!
