All About Pole Spears & Slings What is it about that traditional method of the early hunter/gatherers under the water? These devices are indeed interesting and effective.

Evolve aftershock spear

Does anyone have any experience, or first hand knowledge of these pole spears? Recently I've been hunting shallow reef, rocks and holes more frequently and have found my gun to be too large and cumbersome (not to mention overkill a lot of times). While looking at spears this one caught my eye. Seems pretty slick and the price is right.

Living out on a remote ATOLL, I don't have the luxury of checking gear out in person before buying. Hopefully you guys can help me out here.

Re: Evolve aftershock spear

Not sure if it's a plus or not. Have to assume it is or they wouldn't be marketing it.

When the pole/tip hits the fish you have a fixed amount of Momentum. (Mass * Velocity)

At impact, the internal mass moves forward and thusly reduces the initial amount of momentum available.

Some time frame later , say 2 msec, the internal mass stops moving and the 2nd amount of momentum applied to the fish.

If that internal mass has a triggered spring or something behind it then have the 2nd punch with new energy source. That makes sense to me

Unclear to me exactly what they are doing.

Conservation of momentum and energy hard to get around.

Post a Review if you bought one. Is there a hidden lever to cock a spring?

Re: Evolve aftershock spear

Still in the process of building my own spear and as such have very limited real world experience but I have scoured pretty much every polespear thread here and it seems for your fishing, a CF spear would not be the best. At least that's what a lot of way more experienced spearos have said here in the past. Get an alu one for shooting into holes. If worse comes to worst, your alu spear will bend and you can bend it back - your CF spear will break and you're out of a spear all together.

Another thing I have learned on these threads is just how highly regarded Aaron's and Linghunt's builds are - affordable, too. So, my advice would be to get in touch with one of them.

And yeah, I'd prolly chalk up the kapow/bang/aftershock thingey to a marketing "need" to stand out, but they are still very pretty spears.

Fiberglass poles are great too. They take a beating in marketing world to splintering and hands needing ER and all of that. I found one in the ocean some 15 years + ago. The front aluminum fitting needed to be replaced. Still use it today and works great for me and my use.

I think the "Thread Starter" was looking for more info on that aftershock feature vs pole type selection. Based on time stamp, he bought what he needed long ago.

Re: Evolve aftershock spear

I love mine. I have the 8' with knurled stainless 3 prong. There is no lever or spring. The weight is held in place by a magnet. The knurling makes a huge difference in holding strength and the stainless used it extremely durable. Evan (owner of Evolve) is awesome. I met him in person and he's very knowledgeable and friendly. I HIGHLY RECOMMEND his product!
