SHO Hydrophones detecting enemies before radar does

I have been using one of the single missions to test various mods combinations; i don't think it is a stock mission but one that came with RSRD, USS Flying Fish in 1942 where you are facing an IJN task force who just bombarded Henderson field.

Anyway I have played this mission a dozen times and usually the enemy task force gets detected by the radar first.

But with this new mod soup I am using now and that includes the OTC mod that I didn't use before, for some reason it is the hydrophone that detects the enemy task force at roughly a 10-11 nm range.

I made sure the radar is switched on, set for max range and on continuous sweeps and enemy blips do appear on the radar screen when I go to the station, but it is the hydro that detects the enemy ships first.

Is this normal?

You could try backing the ISP off, and see if there is a difference, but we encounter the same thing in FotRSU. Not an "all the time" kind of thing, but the sonar, especially in the open water areas, will pick-up sometimes way before the radar, given the right circumstances, such as a submerged sub doing Ahead 1/3 (or slower).

Okay thanks for the reply, I am going to remove ISP. I am not sure it affects sensor range but I have had four japanese ships I was tracking on sonar sink in heavy seas and I have a hunch this mod might have caused this incident.

I would think that would not be uncommon due to sound travelling faster through water and not being subject to the curvature of the earth like radar. Sound can travel very far in the ocean.
