Question Combination

[cuneyt ozcan]

Hi I have C4 Mr dark 105 and on it 145cm 6,5 mm spear but need to change. In the shop there is 7 mm 140 or 150cm sigal. Previously my shooting target was higher for I don’t know which reason (6,5 ÖM?). What do you suggest me to do? Go on with 145cm 6,5 or shorter longer 7 mm?

You can improve your aim by using a shorter, thicker spear. The 7mm 140cm Sigal spear is a good option. The increased mass of the 7mm spear will give you a more stable shot, and the shorter length will make it easier to handle. The 145cm 6.5mm spear you currently have is a good all-around choice, but it may be too long for the C4 Mr. Dark 105. The 140cm spear will give you a more accurate shot Official Website

Shorter shafts are generally more difficult to aim with (shooting higher). The increased mass can help with shaft lift (probably due to a combination of reasons - is the flopper down or under, or is the shaft a double barb? What's the rubber setup? etc) but will also be slower so it needs the equivalent setup, increasing recoil.

145cm doesn't have much overhang, even 150 is still doable (this was common in old Beuchat spearguns without the reverse trigger mech).

A good compromise would be a 145cm 6,75mm shaft with 1x16 and 1x14 if the recoil isn't too much but if only a 7mm is available, then a slow shot will also be a more accurate shot. Depends on what the guy is hunting.

Judging by his Turkish-sounding name, even a 6,5mm would do the trick as long as he goes with 2x14,5mm bands. Also depends on the flopper. Shooting high tends to be an issue in close range so if he's taking close range shots (under 3m) he doesn't need a heavy shaft.

move to 7 mm for a stiffer, more predictable shaft; that usually improves accuracy and penetration. A 140 cm 7 mm will feel a bit snappier and cleaner than your 145 cm 6.5, while a 150 cm 7 mm gives more reach but adds weight and can change balance. If you liked the handling of the 145, stay with 6.5, but if your previous shots were oddly high, try the 140 cm 7 mm first . it’s the safest switch to reduce flex and correct POI. Whatever you pick, check fit in the barrel, test a few shots at short range, and re-zero your aim.
