This speargun holds a special place in my heart. It was the first speargun I’ve purchased, and it’s been through a multitude of adventures.
I’ve used the 100cm version for years here in Southern California and in Baja. In this Hammerhead Evolution 2 Review, I’ll cover what I like and dislike about the speargun. We’ll also talk about its features and if I would rebuy it, all things considered.
Hammerhead Spearguns Review

I personally haven’t had a problem with this gun over the past few years. I know guys in Hawaii wouldn’t consider this a good speargun. I’ve learned that the brand isn’t as highly-regarded as I once thought.
Hammerhead Speargun Features & Specs
Hammerhead uses a concrete mix of components in their guns. Let’s take a look at what they use.
Handle
I like the ergonomics of the handle. The plastic contour allows your hand to wrap around it. The white handle is also nice to be able to see the gun while diving in the murk.
Trigger Mechanism
Hammerhead uses stainless steel trigger mechs, which have held up through constant abuse. I’m diligent about rinsing off my gear, and so far, I haven’t seen any corrosion.
The trigger has the right pull for me.
Shaft
Their 17-4 heat treat shafts have lasted through some pretty big fish. I landed 34-pound yellowtail with a flopper with this gun. The shaft wasn’t bent from the seven-minute battle.
The one time I did bend the shaft in a rock, I could straighten it out with my thigh.
Their shafts come with a mid flag and two rear flags welded on the shaft. I like the middle flag for adjusting power around the reef. It’s also helpful while getting started if your arms get tired.
I have recently switched to a Pathos spearshaft, which works great if you want to try another shaft manufacturer.
Barrel
I’m a firm believer that beginners should start with aluminum barrels. It’s less to worry about.
I liked the grove track, which has kept my spear shooting straight from day one.
Muzzle
Hammerhead Spearguns uses an open muzzle design, which took a bit of time to learn when I first started. Don’t worry; once you’ve practiced, you’ll be loading and securing your spear with your eyes closed.
What We Like/Dislike
I didn’t like using a double-wrapped mono shooting line with the 100cm gun. I’ve since switched to a single wrap and use my reel line to wrap around if I need that extra distance.
Would We Buy it Again?
Maybe. Hammerhead Evolution 2 is a workable beginner speargun. I’ve had a change of heart from the first time I wrote my review after talking with one of my mentors. He thought the gun was a POS and classified it with the Makos of the bunch.
Alternative you should consider: Pathos Laser
