Q/A: Had this Question Link sent to me. Real data from my perspective.
Q: I read on a dive forum about you talking about a multiple section Bamboo Pole Spear build. Any chance you will actually get to this or just a dream?
A: Progress on this front has moved forward in 2017. I have been in touch with a diver that is extremely knowledgeable about Bamboo. A couple designs for a joint are in the testing process now. Once that is complete we can make up a batch. This will be a pre-order pole spear. If you are interested in progress and possible purchase let me know. We are going for the Traditional look with high performance.
Q: Float lines; are there any dangers I should consider as a rookie?
A: Drowning at depth is one thought. Float Line entanglements can be very dangerous.
Consider shooting a huge fish and it going to the bottom of the ocean while your hand or leg is caught in the line.

Rider not in a good position, but at least he can breath vs a ride to the bottom of the ocean.
Q: I don't understand the FULL breakaway slip tip rigging setup? Can you send me a Picture, thank you.
A: A Slip tip that "breaks away" means that after the slip head is shot through the fish, the pole is NO LONGER attached to the fish. DON'T drop the polespear. The Slip head is attached to a line that will go to a float system for the most part. Polespears need a Slot, bolt or "feature" on the backside of the pole to hold the line to float. This will allow the Line to not effect the shot.
Note the Tagline on spear shaft with rubber to hold the head on. The Black Mono travels down the pole to slot at rear of the pole, then back to the front of the pole and held in your hand with pole Cocked and Locked for the shot. The Clip on Black mono goes to Floatline.
Below is a Break-away set up for a Mako 3-1 Pole,
and "Yes" the tip setup was much higher in cost than the MAKO 3-1 polespear.
Q: Why would a “Spearo” want to use a pole spear?
A: There are a few reasons most Spearos would want to use a polespear:
- Areas requiring Polespear uses only, due to regulations.
- The added difficulty of the hunt.
- The skill of spearfishing.
Always verify local Game and Fish Regulations, a given anywhere. Why are there so many bow/arrow hunters? They are out to accomplish the challenging aspect of the hunt. Polespear hunters and bow hunters require a higher skill set to produce results. Those divers reflecting on their underwater hunting skills might consider a polespear. Good Pole hunters make great speargun hunters. The opposite can not be said consistently.
Q: What types of Materials are used to make Polespears? What is the best?
A: In the Beginning, polespears were made from wood, bones, leather,and flint. In the modern era with 20th century materials available, Alloys of Aluminum, Stainless Steel, Fiberglass,and Carbon Fiber Composites are most common.
DIY-ers have been know to use old Skipoles, EMT Conduit, and Bamboo. Basic physics for mass, velocity, momentum will drive the materials choice along with cost.
Q: I’ve read the common 6mm-1 thread is really weak, why do you use this thread on your poles vs other sizes?
A: Not all Linghunt polespears have 6mm-1 threads, I'm happy to change the thread per request to mate up to your existing stack of spear tips. Most divers want 6mm-1 for it's common and easiest to find. The strength of this 6mm thread is a valid concern.
My solution is to provide this thread with more strength. I use a male thread that was formed , not cut. In the process of forming a thread, the grain structure has more stress, ~30% more strength.
The left image shows how cold forming compresses and redirects material grain, increasing thread strength. A cut thread, shown at the right, interrupts the grain.
Remember; Tighter joints are always stronger.
Q: Why do you sell that small clip with each polespear?
A: It is a stow clip used to hold the pole off of a float or Dive board when not in use. I came up with this by swimming up to the surface in a murky kelp bed. The tip of the spear hit me on the head, which then inspired the idea. With the pole on the clip, the spear tip is safely out of the water and away from any Spearo's head.
Q: Why did you put so much design effort into the polespear joint?
A: I had this concept before I had a CNC Lathe. This is a tight toleranced computer controlled machine. I was now able to make this concept a reality. I wanted a joint that:
- Prevented cross theading
- Keep the sections aligned straight, vs crooked
- Water Sealed connection to prevent flooding
- No more, TEFLON TAPE or sealers to hold the connection together.
- A joint that does NOT get LOOSE out in the water.
Have you been out diving and find your pole is half unscrewed and full of water? or find you lost half of your pole. Well, me too. I wanted this problem to go away.
The geometry of the connection also removes the threads as a weak spot as well.
The weak link is the tensile strength of the thick walled aluminum tubing.
It is a solid, strong, leak proof, thread locker, easy to assemble, and perfectly aligned joint, that is what I wanted and what I got once the smoke cleared.
Q: Is your pole actually the length you say it is?
A: The LINGHUNT pole is actually a little bit longer than what is called out from length of fittings. [ a 6 foot pole is closer to a 6 foot plus 1 inch ] I don't want you to put a tape measure on my pole and expect 6 foot and get 5 foot or even one inch under and feel screwed.
I do not play the "SHELL GAME" in which the pole length means to add the tip length in the fine print. If you buy a 6 foot pole, it will NOT be a 5 foot and then 6 foot with a 12 inch tip on it.
Q: I plan to dive in the Bahamas next summer, how long of a pole do I need?
A: Diving in the Blue water, Spear-o's typically buy my B3021-3 or B3121-3. This is a 5 piece pole that can be up to 8 1/2" foot long ( 4 - 2 foot sections, and a front 6 inch section).
1 section can be left out for in close work on the reef , or 2 sections for a 4-1/2 foot pole for hunting Lionfish. You can also add a section in front of the grip or behind to provide the diver setup options.
- IN BACK: More band stretch length
- IN FRONT: Get the tip closer to target with respect to your body
Q: I dive along the Oregon coast, what Pole length should I consider?
A: Oregon is similiar to the Cold Waters off of Northern California. A 6 foot pole works well for the Blue Rockfish in the kelp beds and the LingCod hiding in a hole commonly seen on the Oregon and California coast.
The B3121-4RF Polespear is a local favorite along the Northern California coast line.
3 different setup base on clarity of water and hunting terrain.
FIXED TIP and maximum length with tip is 6-1/2 foot.
Q: Do you make these or do you sub the parts out to China or Mexico for lower operating costs?
A: I make the parts myself with the help my son that is currently in College. I don't buy parts internationally and fondle the parts in assembly and call it "American Made".
Got to watch the jargon out there on most topics.
