Hi @abubakrazam,
The Ping Sonar’s beam should be roughly conical - it’s not designed to have a narrower beam width in a particular orientation, because it’s intended for measuring distances to anything in front of the sensor. The Ping360 has a narrower horizontal beam width because the sensor can rotate in the horizontal plane, so having a large conical beam for that would result in much less usable horizontal precision.
Note that individual beam width numbers are rough guides that are indicative for practical usage, but actual beam shapes can be quite complex. We’re working on providing a more complete beam plot, but the testing for that isn’t finalised yet
