Casing Collar Locator
More Durable. Better Function. Better Grip.
Yellow Jacket ExclusiveThe patent pending Yellow Jacket passive Casing Collar Locator (CCL) for e-line/ wireline is an upgraded version of the industry standard CCL design.

Wireline Junk BasketDesign enhancements such as a double wound coil, pressure bulkheads and stronger, permanent magnets provide a better functioning, longer lasting tool.

Cleaner Signal
Increased wound length and dual coil winding increase signal strength and clarity while providing system redundancy
Stronger, permanent magnets enable higher feedback levels
Reduced Risk of Flooding
Pressure bulkheads on both ends prevent CCL flooding due to seal failure above or below the CCL
Longer Lasting
Tungsten carbide inserts protect the housing and subs by reducing contact with well casing
Double wound coil provides a back-up system: if one strand breaks, you still get a signal
Permanent magnets never require recharging
