Please provide the dimensions... Overall length when the spear is retracted, length of the spear (looks to be 24" based on the question below),and length when extended (with or without spear tip).
(here's the mandatory question mark ?)
The ELF from Leisure Pro is 18" long overall, end to end, without an added tip. The handle (injection molded plastic) is 7-7/8" long. I can pull spring back about 9-10" (the length of the shaft beyond the front of the handle) and it pulls back smoothly. I use a Trident HA08 tip, 6" long with three barbed points. However, I have just upgraded the shaft to a 29 1/2" (75 mm) stainless steel rod (threaded 6mm on both ends) to give me a bit more "reach" to hunt lionfish. The ELF is the only approved tool that may be used on Bonaire and it must be registered with the Marine Park. There is another model of ELF with a stronger spring that I cannot pull back as far. That one also has a solid Delrin handle. So far I am very happy with the ELF from Leisure Pro. I've killed 3500+ LF on Bonaire since 2010.
As shipped the ELF is 24" but the draw is about 14". I replaced shaft with a 30" shaft and use a parrallizer tip.
There is no change in the overall length of the rod as the handle simply slides on the rod. The spear does not extend or retract. I do not have the ELF where I can measure it, I believe the tip is about 4 - 6 inches.
Overall the length should be under 30 inches, but only 24 inches with the tip removed.
The length of the spear is 24 inches and does not change. The shaft is bolted to the butt end of the handle with a spring inside the handle. You hold the front part of the handle and pull the butt end back to extend the spring and then let the butt end go to fire spear. You keep holding on to the handle when the spear slams forward. The travel depends on how strong you are. It is possible to pull it back until the tip hits the handle.
Thank you Susan. That information helps quite a bit.
