Do Destroyers and Escorts use different sonar/hydrophones?

[Bubblehead1980]

Noticed Destroyers, even when set to elite, even in later war, with exception of Akizuki usually lack the zeal and ability to track and kill my sub as opposed to the escorts.Just wondering if they use different equipment or? Example: Feb 1944. Matsu No 1 Convoy(I added this convoy to RSRD) off Okianawa(convoy carrying troops from Manchuria to Guam) Trout attacked, later destroyed by her escorts in area Closet. I had the USS Trout actually and testing to make sure convoy turned up at correct place on historically accurate time/date, I went to the area and made contact at correct location at 1230 on 29 Feb 1944.

Attacked, sank large troopship with 6 mark 18 torpedoes from 3,000 yards, sunk other with stern tube Mark 14's. Then went deep as 3 Yagumo DD's closed in. They seemed to never really have a lock on me despite ideal sonar conditons, I was making plenty of noise for a while during the follow up attack and was at Trout's shallow test depth of 250 feet.Some close charges shook boat, some minor damage in one case but soon after they lost me and gave up.These escorts were all set to ELITE but acted like total amateurs.

Night surface attack sank another, then follow up dawn attack I sank last transport plus a DD that strolled in front of me while Mark 18's were en route to target.As soon as the last four mark 18's hit, tubes 5 and 6, which had mark 14's were fired at the Yagumo DD that was just 1200 yards in front of my, one hit amidships despite his attempt to speed up.The DD's rushed in dropped some charges, then never pushed home the attack/

Had I conducted myself like this around escorts like the Type AB or C/D etc, I would have been in trouble.The lack of tenacity in supposedly elite destroyers disturbed me.Trying to figure this out.DD's were much better sub killers than this.

Noticed though that when tangling with most full sized DD's, they lack the effectiveness(exception being the Akizuki) .Anyone else notice this? Anyone know why this is? Different equipment?
