I shot that bad boy while freediving, I always freedive when spearfishing.
The Gun is a 55" Titanium Daryl Wong Hybrid.
All daryls guns are completely customized to the customer and all hand made by Daryl himself. He will even paint your name into the gun for free! It is by far the best gun I have ever had, it is deadly accurate, easy to maneuver through the water, and has enough power to take down a huge WSB yet the accuracy to stone a 2lb calico.
All the info is available at daryl's website

He is also one if the nicest people I have ever dealt with, the service is great!
I like the 55" because it is small enough to use locally yet has the power for mexico and catalina.
But If I had a boat and could do more kelp/offshore diving I would also get a 60" gun.
I am not affiliated with daryl in any way, just a very, very happy customer
