About Sonotrax Pocket Doppler

Soontrax is made by Edan Instrument Inc. which is named by Forbes Magazine as one of best growing potential company . Sonotrax is by far the best brand of economical priced medical Doppler for its durability and reliability.  Edan offers variety models of sonotrax Doppler for different demands. Buyer should understand what model you are buying , Beside the common feature of :

• adjustable audio volume
• High sensitivity interchangeable probe
• Support  2MHZ, 3Mhz ,4MHZ,8MHZ waterproof probes
• Long time continuous use
• Automatic power-off

 If you plan to purchase a Sonotrax Doppler on Ebay , you should pay attention to the follows

1)            Some sellers use “professional use”, “professional grade” , “professional model” etc to imply that they are selling “Pro” Model . Actually they are selling Basic model . Only “pro” model has the audio play back function.

2)            Some sellers sell “Sonotrax-B” like picture below , This is not Sonotrax Doppler in stead of Sonoline made by another manufacturer. Sonoline A/B Doppler with 2/3 mhz probe  approved by FDA recently .  

3)            Vascular Doppler and Fetal Heart Doppler are slightly different. Although the 2,3,4 ,8mhz probe is compatible with  any model of Sonotrax Doppler body. The compatibility does not mean best performance.  While Fetal Doppler captures the fetal heart movement and the rate , the vascular Doppler needs to capture even smaller blood flow in artery or vein . Usually 2,3mhz probe are used  for fetal heart movement detection , 4 mhz can be used for either fetal heart detection , or upper arm/leg , thigh .  8mhz probe are usually for lower arm, lower leg blood flow detection. If you use the Doppler for vascular purpose only , we strongly recommend the Sonotrax vascular model. The performance will pay you because the Sonotrax Vascular is specially tuned for vascular application. Also some seller on ebay will offer a Sonotrax Lite instead of Sonotrax Vasculer , Please mind the difference.

5)            Edan Instruments offers 4 different probes . Generally the lower frequency , the deeper detection, the lower resolution.    All these Doppler probe emit continuous ultrasound beam , they are designed for spot check which means that each exam should last only a few minutes , check are occasionally . Calling  these Doppler a monitor is not correct because they are not designed to continuously use on fetus. There is one fetal Doppler using same technology of hospital grade fetal monitor technology , the PC-860B monitor using 1mhz pulse beam emit much low dose of ultrasound emission. PC-860B is much safer for using in middle or later term of pregnancy if intensive checking and monitoring is needed. PC-860B can be found from our ebay store too.
