Systems and techniques for locating a tool component in a channel of a blowout preventer. The system and technique may include the use of glide rams that are configured to sealably engage a deployment bar of a toolstring supporting the tool component in the channel. The glide rams may allow for movement of the deployment bar and toolstring while maintaining the seal. Due to greater diameter of the tool component, contact with the rams may be detected in the form of a spike in load detected at an oilfield surface by equipment supporting the conveyance means for the toolstring. Thus, tool component location may be ascertained. This same diameter difference of the tool component may also be utilized to deflect a member in the channel for sake of tool location.
