The HRUSB-MaxSonar-EZ3 is a narrow beam sensor with good side object rejection. The HRUSB-MaxSonar-EZ3 has slightly wider beam width than the HRUSB-MaxSonar-EZ4 which makes it a good choice for when the HRUSB-MaxSonar-EZ4 does not have enough sensitivity for the application.
The MaxBotix high resolution MB1443 HRUSB-MaxSonar-EZ4 has a narrow beam and is an excellent choice when only larger objects need to be detected.
The MaxBotix high resolution MB1413 HRUSB-MaxSonar-EZ1 is a great choice for use where sensitivity is needed along with side object rejection.
