am i experiencing a bug or a normal game mechanic?
 

i am having issues with sonar range reports, i have tried this with the realism setting for sensors on and off but it seems to make no difference.

if i am in water less than 100 meters deep my sonar goes absolutely bonkers, not the hydrophone mind you, range finding sonar. when i ping a target if i am lucky the range will be accurate to about 50 meters. if i press it repeatedly the range drops in increments of 100 all the way down to 0. and often i can be looking at a ship on the map getting its approximate range using the compass to get an idea of how far it is, then when i go to sonar it gives me a report that can be as much as 6000 meters off.
now to top it off? i go into a mission and spam the sonar button on a target and its accurate (barham)

SH3 1.4 patch GWX 3.0

what in gods name is going on? do i just need to fire my sonarman at the next merchant or do i need to reinstall (for the third time in trying to fix this)

Hi, this also happens to me! when I make multiple pinging, the displayed range increases or decreases..

I use GWX2.1


Any fix?
