understood that other release members such as shear screw s parting ring body lock ring collet etc could be substituted the release member 26 provides a signal to an operator indicative of a restriction by holding some selected amount of weight and then releasing causing a slack off in weight on the derrick not shown at surface and then a return of the weight or in other words a spike except in the negative direction with respect to load the amplitude of the signal is dictated by the release value of the release member 26 and can be adjusted during manufacture of the system 10 referring now to the load isolation device 46 this feature provides the function of ensuring that the anchor system 10 sets only at a selected location such as the bottom of a borehole in which the anchor is to be used or at a landing profile discussed hereunder as alternative embodiment intended to cause the actuation it ensures this by presenting a significantly lesser gage diameter than other components of the system 10 this helps in the function of the system 10 in that it predisposes the actuation of the system 10 at the selected location such as the bottom of the borehole or at a landing profile as is intended because the collet is of significantly smaller gage diameter the likelihood of being actuated by a restriction is consequently smaller the collet 46 is releasably secured by a.
