Navigator GPS


The Navigator GPS has been a trusted and reliable choice for gamma detection in the surgical suite for well over a decade. Surgeons and OR staff favor the Navigator GPS for its simplicity of use and portability. Unlike other systems, no calibration from probe to control unit is required before use; the system is ready to use the moment it is turned on. Its primary features include:

Lymphatic Mapping Gamma Probe Instruments – Sentinel Node Gamma Probe Instruments – IntraOperative Tumor Localization Gamma Probe Systems – Navigator GPS

Navigator 2.0 Stand

  • The Navigator 2.0 custom cart enables fast, efficient setup and maximum visibility in the OR. Between cases, the cart provides safe and secure storage for the complete Navigator 2.0 System and accessories.

Wireless probe battery

  • Disposable life Li-ion battery

Wireless dongle for GPS (upgrade, including probe)

  • Provides compatibility to use wireless probe with the earlier generation Navigator GPS. Gives visual indication of isotope setting used with Navigator GPS.


  • The optional Co-Pilot device attaches to the handle of the probe, allowing the surgeon to initiate a ten second count and adjust the audible range as desired.



  • The Navigator collimator is an optional accessory device that fits directly over the tip of the Dynasil Standard Lymphatic Mapping Probe, increasing precision and focus by reducing the field-of-view to 40 degrees.
