A sensor disposed at the body configured to detect when a tool run through the tubular has reached the body. A signal generator configured to send notification that the tool has reached the body; and a plunger configured to cause the signal generator to send notification upon being urged relative to the body. A method of verifying a tool. ## Claims ### Claim 1 An indicator comprising: a body configured to be run within a tubular from a first portion to a second portion of the tubular; a sensor disposed at the body configured to detect when a tool run through the tubular has reached the body; a signal generator configured to send notification that the tool has reached the body; and a plunger configured to cause the signal generator to send notification upon being urged relative to the body. ### Claim 2 (depends on 1) The indicator of claim 1, wherein the tool is a measurement tool. ### Claim 3 (depends on 1) The indicator of claim 1, wherein the indicator is configured to be pumped through the tubular. ### Claim 4 (depends on 1) The indicator of claim 1, further comprising wings extendable from the body configured to orient the body relative to the tubular while being run therethrough. ### Claim 5 (depends on 4) The indicator of claim 4, wherein the wings are radially movable relative to the body. ### Claim 6 (depends on 1) The indicator of claim 1, further comprising stabilizers configured to fix the indicator to the tubular. ### Claim 7 (depends on 1) The indicator of claim 1, further comprising at least one stabilizer configured to extend from the body to engage with the tubular after the body has reached the second portion. ### Claim 8 (depends on 1) The indicator of claim 1, further comprising a release member configured to cause the at least one stabilizer to extend from the body upon the release member being urged relative to the body. ### Claim 9 (depends on 1) The indicator of claim 1, wherein the indicator is configured to self-orient relative to the tubular upon reaching the second portion. ### Claim 10 (depends on 1) The indicator of claim 1, wherein the sensor includes at least one of an accelerometer, a switch and a mechanical actuator. ### Claim 11 (depends on 1) The indicator of claim 1, wherein the signal generator is configured to emit a signal. ### Claim 12 (depends on 11) The indicator of claim 11, wherein the signal emitted includes at least one of electromagnetic energy, radioactive energy, seismic energy and acoustic energy. ### Claim 13 (depends on 1) The indicator of claim 1, wherein the signal generator is configured to send notification that the body has been contacted by the tool. ### Claim 14 (depends on 1) The indicator of claim 1, wherein the signal generator is configured to send notification that the indicator has reached the second portion. ### Claim 15 (depends on 14) The indicator of claim 14, wherein the signal generator includes media initially stored within the body that is detectable upon release from the body upon rupture of the body. ### Claim 16 An indicator comprising: a body configured to be run through a tubular from a first portion to a second portion of the tubular; a sensor disposed at the body configured to detect when a tool run through the tubular has reached the body; and a signal generator being configured to send notification that the tool has reached the body, wherein the signal generator is configured to emit a substance stored therewithin. ### Claim 17 (depends on 16) The indicator of claim 16, wherein the substance includes at least one of a colored die, a particle tracer and a radioactive tracer. ### Claim 18 (depends on 16) A method of verifying a tool has reached a second portion of a tubular comprising: running an indicator as claimed in claim 16 through the tubular from a first portion to a second portion thereof; running a tool through the tubular to the indicator; sensing that the tool has reached the indicator; and sending notification from the indicator that the tool has reached the indicator wherein sending notification includes discharging a substance from the indicator. ### Claim 19 (depends on 18) The method of verifying a tool has reached a second portion of a tubular of claim 18, wherein the running includes pumping. ### Claim 20 (depends on 18) The method of verifying a tool has reached a second portion of a tubular of claim 18, wherein the fixing includes extending stabilizers. ### Claim 21 (depends on 18) The method of verifying a tool has reached a second portion of a tubular of claim 18, further comprising orienting the indicator relative to the tubular after reaching the second portion. ### Claim 22 An indicator comprising: a body configured to be run through a tubular from a first portion to a second portion of the tubular; a sensor disposed at the body configured to detect when a tool run through the tubular has reached the body; and a signal generator being configured to send notification that the tool has reached the body, wherein the body is the sensor and is configured to sense that the tool has reached the body by rupturing of the body. ### Claim 23 A method of verifying a tool has reached a second portion of a tubular comprising: running an indicator through the tubular from a first portion to a second portion thereof; running a tool through the tubular to the indicator; sensing that the tool has reached the indicator; and sending notification from the indicator that the tool has reached the indicator, wherein the sensing includes compressing a plunger. ### Claim 24 An indicator comprising: a body configured to be run within a drill string from a first portion to a second portion of the drill string; a sensor disposed on the body and run through the drill string with the body configured to detect when a tool run through the drill string has reached the body; a signal generator on the body and run through the drill string with the body configured to send notification that the tool has reached the body. ### Claim 25 (depends on 24) The indicator of claim 24, wherein the tool is a measurement tool.
