About JBL Explorer Lightning Single Sling Spear Gun (4D22-L)

If you're looking for a spear gun that's big on performance while still leaving a little green in your wallet, the Explorer is perfect. Made with a corrosion resistant hardened 17-4 stainless steel trigger and shaft, JBL738SBF shaft is 38" (96.5 cm) long with a 9/32" (7.11 mm) diameter, cast aluminum, two piece handle, and combined with a 1" (2.5 cm) aerospace alloy barrel for quick target acquisition and fatal results. The Guns overall length is 42" (1.07 meters) Same parallel power source and low profile design make the Explorer perfect for cagy fish when the shot window is a split second. The Gun range is 17' (5.18 meters).

To increase power and additional 5/8" (16 mm) O D JBL420 sling can be added. The sling is a unique latex formulation and dip manufacturing process that delivers radical modulus strength. The power curve increases as bands are stretched for optimum performance. The Special anti-oxidants help protect against harmful U V rays, prolonging sling life. The slings wishbone is 302 stainless wires that provide superior strength and durability.

The Gun is equipped with the JBL515L Shock Line. Sometimes we miss or we shoot a large fish and the recoil can pull the gun out of your grip, which ever the shock line will keep you in control. The Explorer Lightning Guns all have a shaft with integrated point and barb, no need for an extra spear tip. However since the tip is still threaded, if you wish, you can add adapter JBL815 which will then let you connect any 6mm JBL spear point. The Lightning models feature Tru-Glide rail and shaft. These guns are all about speed and accuracy. At the end of the day it's not the flash, but the fish count that really matters, and nothing stacks them up like the Explorer.

Questions & Answers Powered by TurnTo®

Questions about this item:

John M  Can you replace the spear tip? How do you remove the tip to put on a different one?
Eric K  The spear that came with my 4D22-L does not have a replaceable tip. If you want this spear gun to have a spear with a replaceable tip you'll have to buy another spear for it. Even though a replaceable tip is desirable I would still buy another gun like this in a heartbeat because it is a terrific gun. Also where I spearfish there are few rocks and I have not needed to even resharpen my original tip since I am usually very careful when shooting around rocks. It is also good to not have to worry about a screw-in tip falling off, which it will do if you don't check it often. I hope this answer was helpful.
Shopper  There aren't any specs on this gun. Can you send me some?
LeisurePro S  The overall length of the gun is 44", the shaft is 38" 9/23 diameter and a reach of about 17 feet
Shopper  This gun looks just like the JBL Explorer 22 speargun. Can you tell me what the differences are?
