Cascade HealthCare Products carries a wide selection of Summit LifeDop Obstetrical Doppler Probes including transvaginal and waterproof probes. All LifeDop obstetrical probes provide a specific purpose as noted below and are able to be used with all the LifeDop series Dopplers.


  • 2 MHz Probe: The Wide-angle beam is optimized for deep penetration needed in late term pregnancy and larger patients.
  • 3 MHz Probe: The best general-purpose obstetrical probe for fetal heart detection, from earliest stages through delivery.  The probe's wide-angle beam saves time spent "hunting" for the heartbeat.
  • 5 MHz Transvaginal Probe: The 5 MHz transvaginal fetal Doppler probe is used for early fetal heartbeat detection.  It is ideal for women who are obese or have a retroverted uterus.
  • 2 MHz Waterproof Probe: Waterproof design is optimal for water-assisted labor and delivery applications.


  • Latex-free
  • Non-directional
  • Excellent sensitivity
  • Maximum durability
  • Completely interchangeable for use on L150, L250 and L350 series of Dopplers
  • Interchangeable probes make it convenient to use the same LifeDop Doppler for multiple purposes

*All Summit probes are covered under a Wallach Surgical's warranty and come with a two (2) year labor and two (2) year parts warranty. For more details, click here to be redirected to Wallach Surgical's webpage.
