I recently finished rigging a 4 banded conventional 140cm speargun. Been trying to fine tune it and make it consistent and reliable for tuna. I acquired the actual gun for free, just had to pay for parts and rig it myself. I decided to put 14.5mm small ID bands from MAKO on the gun; recommended by multiple people at Spear America due to mass of the gun being lower compared to other brands. The band holes are drilled for 5/8 or 16mm bands.
I have been getting consistent line wrap on the gun. Video attached. It is set up with 2.5 wraps for breakaway. Some potential causes I am thinking:
- Bands have too much play in the holes
- Slip tip not tucked properly. (I have been tucking it under the line wraps on the anchor, similar to how it is recommended on Andre inverted rollers.)
- Bands too long
- Wishbones too long/short
- Wishbone inserts are too heavy, causing the ends of the bands to fly in front of the muzzle and get tangled in the shooting line. (stainless steel, picture attached)
- Shooting line anchor at muzzle is too far off of the gun, causing a large angle to be made in the shooting line and wrap in the bands.
Please let me know your thoughts. I typically shoot rollers and inverted rollers, so would like some knowledge from guys who prefer conventional setups. Thanks! (All pics included at end of video)
