Duplin Bipod ?

How do you adjust for height? Is it the mariner wheel looking pieced under the center? And this is for gross height adjustment or for fine adjustments?

I think I am switching to it or the centshot bipod. I read reviews and threads and it appears Duplin is the way to go??
 
I like mine. Light, rigid and adjustable. The only one that might have an advantage is Seb's Joypod. [br]
Scott, have you seen Mid using his? If so, what did you think?
 
I am having issues with my Sinclair fine adjustment screw having backlash and also it not holding the cant angle. Everything is tight so going to return it and get the Duplin I believe and add a rail to the forend of the stock
 
I had the same problem with my Sinclair not holding cant and being hard to adjust smoothly. Took the thing completely apart and put polished stainless washers on each side of those plastic friction washers. That solved it. The finish on the metal without polished washers is too rough for the friction washers to move easily.
 
So the Duplin doesn't have much flex if any in it?
My Sinclair has a "good bit" but then again never used another one.

Anyone know what the joypod might cost?

Yes, I've watched Mid working with the Seb, novel concept...not sure it adds any value for my style. I am a bag squeezer and have a bit of taper on the buttstock that I use for elevation adjustments. Probably comes down to personal preference...I prefer simple, rigid, and light! :-)
 
I'm very happy with my Duplin bipod; Weight is just right, but the adjustability is what grows on you.
- How many times have you broken position to adjust the legs of a Sinclair?
- Not to mention, the elevated heart-rate and stress when it's still not right and your 3-minute prep is up. >:(

The Joypod looks like an interesting alternative.
- How much can the Joypod be adjusted, using just the stick?
- What's the hight/side-change ratio on the pod-stick in moa/mil for inch/mm movement?

Wouldn't that depend on the length of the stock between the bipod and the rear bag? If a shorter stock, 1 mm of lateral travel would result in a greater deflection than a longer stock?

Answer:
Travel movement on the coaxial head unit is approx. 7.6 milimeter (=.0.300") from side to side, and approx 5 mm (= 0.200") vertically.
Just for instance: IF the center to center between the front bipod & the rear bag is 30 inches and target @ 1,000 yds (= 36,000 inches) - the joystick movement alone will give you approximately 360 inches (= 30 feet) side to side coverage and +/- 240 inches (=20 feet) vertical coverage @ 1,000 yards.
However the effective vertical travel is about 1/2X or less, assuming that your joystick hand needs to sit on the ground/ shooting mat, not "floating" in the air).
The shorter the distance between the bipod and the rear bag, the greater the coverage.
Vice versa, the longer the distance between the bipod & rear bag, or the shorter the distance of the target - the smaller the coverage.

The math is simple anyway :
.300" movement @ 30" = equal to 360" @ 1,000 yds or 36,000". (= 1/100 ratio).
.200" movement @ 30" = equal to 240" @ 36,000" (= 1/150 ratio).
(This is the same thing/can be applied when calculating the angle/MOA for scope's base).

In Raton, when I centered the joystick & crosshair on the bull of my target (for instance on target #16), I could aim the target right & left next to my target (i.e. target #15 and #17), horizontally.
That was when the scope set @ 50X power. (But I did set my scope @ 30 to 40X to be able to see my neighbor's targets during the string, not to "reduce" the mirage or its "apparent" movement on the target).
The effective vertical coverage was about twice (2X) the size of the target.

Hope this answer the question. Seb

Yes, very much so :)
 
I have bought and used the Sinclair Gen 1 & 2, Centershot, and a couple from Europe. The Duplin Bipod is the best I have used and would recommend it over the others.

Clink said they have some in stock, ordered one today, looking forward to trying it out.
 
I have right at 55 folks on my J-Pod wait list, and it is growing on a weekly basis (Close to 1 every other day in August).
Seb is planning on starting production after the first of the year. GUESSING sometime in February ;D
From what I remember he plans on doing a large first run. I need to get that # confirmed before I throw it out there.
I take care of the US and Canada, but he also will have all the other world orders as well.
I would suggest if you are seriously considering one, get on the list now.
Once these get out and are being used, I think interest is even going to be higher.
It is so easy, even a preacher can run one ;)
I think some guys got on the list the first day they heard about it, as I have three guys who got on the list on Oct 23, 2012, and another got on on the 28th.

are bipods of this type we have mentioned more stable using a rail vs the swivel mount?

Ernie how long is the wait for the joypod?
 
I sure like mine. The mariner wheel height adjuster is saving my knees and the light weight is a real plus. Mounting options are good too. I like the Picatinny option.
