Gareth,

I used a lot those guns were I was living in Venezuela, they are good and very simple to mantain. The model Ataque is the bigger and more powerful.

But any modern pneumatic speargun has a better performance that those guys. We changed like 15 years ago to rear handle pneumatics and now upgraded with mamba systems.

The Cobras do not shoot as good as these other guns.

If i can help you with more information, just let me know.

Cheers

Ivan
