Hammerhead Evolution2™ Speargun

EVOLUTION... the incremental succession of speargun perfection.

THE MOST ACCURATE speargun in America as independently tested by Hawaii Skindiver Magazine* and Spearing Magazine out of Florida**.

Confidence in your ability and equipment puts fish on the plate. Every element of the HammerHead Evolution2™ complements the next for consistent and accurate shots dive-in and dive-out under the most demanding of situations.

Created by HammerHead Spearguns founder Kevin Sakuda for unparalleled accuracy the HammerHead Evolution2™  starts with the Evolution2™ Open Muzzle based upon the original Reef commercial spearfishing design that started HammerHead.

Powering the HammerHead Evolution2™ are twin circular Power Helix™ Bands, the first ever interchangeable wishbone system commercially available.

All Evolution2™ Spearguns are then matched with precision-machined American made 17-4 Stainless Steel Heat Treat Shafts designed with weld fin tabs set 2.5" from the rear to maximize band stretch and power.

Contoured ergonomic grips maintain the divers wrist in "strong-fist" position allowing the diver to maximize their strength while firing to prevent recoil and kick with increasing shot power.

Finally each Evolution2™  Speargun is professionally rigged by hand right here in Hawaii with mono shooting line, loading pad, and front-end bungee all standard features.

» Open Muzzle - Dual Bands
» Pistol grip
» Easy to use, one handed safety
» Stainless Steel Side Line Release
» Stainless Steel Trigger Pull
» Reverse Trigger Mechanism - Max band stretch, more power.

Recently I had the privilege of being able to hunt the water off of San Clemente Island, Ca. The only thing better that the 40-60 foot vis and the company in which I was diving was the performace of your 110cm Evolution Speargun. I was able to take fish after fish with superb accuracy and reliability. I was so pleased with toyt product that I had to say "Thank You" to you guys. Keep up the good work.

Open Muzzle and two strong 9/16th bands with cord wishbones made this gun easy and safe to reload. Gun was very accurate and the built in track made for easy reloading.

The sea is teaming with large fish for us to spear. I just thought I would take a second to say that the 130 cm Hammerhead gun worked flawlessly on my Tuna trip. I used it for a back up shot on a 190 and 160 pound YellowFin tuna. You have some of the best equipment around.

— Dan S.

i just got my 120 and tested it yesturday ..............and shot a blue uhu. . . . . . . . . . . . . . its sick...........keep up the good guns. shoots

Hammer head guns and accesories are Da best! i got my largest fish/my first ulua with your gun in 110cm.

— Jace R.

Well, just went diving today with the new Hammerhead Evolution speargun I got while in Oahu.  The first shot with this gun was on a nice sized Uhu. When it was within range, I let her rip. STONED! Not even a twitch. I was shocked because I've used other pipe guns, but with the HH muzzle that fits perfectly to the track, the shaft flew exactly where I aimed.

Well, I was able to take out the 75cm HammerHead about a week and a half ago. It's freakin Awesome! It moves great in the water, Super quiet and fast to reload. I took 4 carp in really bad vis. The others out that day got 1 or 2 carp. I would actually shoot one carp and the other carp around wouldn't take off like before, just keep swimming like nothing happened- It was cool.  It is now my Favorite gun and everyone wants to try it.  Great - Great Gun!

I actually like the HH better than my other gun! Less recoil, American made, and pin-point accuracy.

— Dan S.

My HammerHead 120 cm is incredible. I can not miss. My shot on a knifejaw was the best. It’s a good-one.

My Evo hits right where I aim. I got my biggest AJ on a rig about 30 minutes before dark. Jumped in and had about 20 ft viz but it was pretty hazy. On my second dive, I saw it out of the corner of my eye and made a couple kicks toward it. Took a 10 ft shot and hit exactly where I was aiming(right behind the gill plate). he put up a pretty good fight, and by the time I got it to the surface my shaft was trashed.

The HammerHead Evolution is my around gun. Its great not having to put so much upgrades into the gun considering that the evolution comes stock with all the upgrades you would usually make on a euro gun.

I was in the market for a new speargun after a close call with a metal wishbone. Being a beginner I wanted something reliable and popular. I didn't see much HammerHead out at that time, but the design was like a eye candy. I had doubts because I wa a beginner and was used to open muzzles. I went home that night holding a HammerHead Evo 100cm and could not wait to use it the following day. I jumped in the water, pulled back the bands (impressed at how simple it was load) and headed out to look for dinner. I dropped down, squeezed the trigger and watched my shaft go through the gill plate of a #9 uhu. Reliable, Accurate, Deadly!!! Just what i wanted!!!

Hello, I just want to share how I love my Hammerhead gun. It held its ground against a 5 foot 40 pound Leopard Shark with no reel or float. The shaft did not even bend an inch. It was taken with an EVO 100cm.

Gotta be the new gun. 11 pound omilu and a 10 pound uhu

— Brandon T.

Hello, several days ago, i sent my speargun to honolulu because the pin in my muzzle had broken off. I sent the gun in on a tuesday, and i got my gun back on friday! I was extremely impressed with the service i received and i\'m ecstatic because now i can go out tomorrow (today is saturday). I also noticed that the person who took care of my gun also swapped out my plastic line release with a metal one and sent me a t-shirt along with my gun. The evolution speargun has really impressed me with it\'s accuracy, but it hasn\'t impressed me as much as your customer service. Thanks again :) your loyal customer, Reece

— Reece

Let me start by saying thank you and your team for having such EXCELLENT customer service. I’m still a little shocked on the follow up e-mail you sent me cause I've never seen a company care that much about its customers. Anywho the new SS line release is AWSOME and being the first person on Maui to have one makes me smile just thinking about it. Took out my E2 yesterday actually and got a couple Kalas for mother’s day dinner. I was very impressed on how accurate it shot, how user friendly the safety is, and the details you guys put into it. I can't thank you guys enough for giving me such great service. Keep up the outstanding job guys I really mean it.

— Mark J.

I wanted to thank you for helping me pick the right gun for both my Hawaii reef free diving and my Pacific NW spear fishing.  It has worked perfect for both.  This is a pic from my first time out after returning from Maui.   Nice bag of Ling Cod.
