even just the silent recon missions.. i just have to keep at it.
I did do alot of TMA on 688 using tpk and locking that, lining up dots etc so quite comfortable with that but sometimes i think i get duplicate contacts from sonar to towed that are close and have a hard time knowing if its the same one or not, esp if narrow band shows different signals overlapping - even more confusing when u have clusters :/

No problem!
So, you need to find tracks on the towed's narrowband first. The spherical's broadband is going to be one of the last ways you detect a track - usually too late to be of any use (remember, this doesn't apply to 688(I) Hunter/Killer. Narrowband > broadband is for Sub Command and Dangerous Waters). Narrowband is better for searching for the reasons I gave before and because the towed has a further detection range than the spherical because the towed detects lower frequencies, which travel further than high frequencies.
Also, you should trust your TMA to give you a target's speed. DEMON should be used more as a check against your solution than the basis. If you have a faint track, you won't see all the blade lines in DEMON and that will give you a false positive on what you're tracking. In addition, you need to have a broadband track to get DEMON data and if you're tracking a sub, waiting to get DEMON on it (i.e., waiting to get a broadband track) will usually happen much too late in tracking the target to be helpful. You're going to have to guess different speeds in the solution to find the correct one - of course using your intuition that the vast majority of submarine contacts, for example, will be going under 10 knots.
So it sounds like you really just need to revise your workflow order. It should be towed narrowband first and then when you get the broadband track, you can use that to determine the contact's direction if you haven't already and verify speed.
Multiple towed tracks are a pain in the ass, yes. But if you're going against a single target, it's usually not too bad. But tracking any kind of strike group or fleet can be a royal pain. Feel free to let the autocrew sort through that mess! You're the captain first
. Doing TMA and determining who is real and fake does require a lot of maneuvering, unfortunately, unless you can sync up tracks from the spherical or conformal. But please be careful doing that as it can be hard to realize if you've merged the wrong tracks. I recommend developing all sierras of interest into separate solutions first, then see if they line up closely on the nav map before merging.
