Simrad Transducer

Hi all,
Im new here and have been having some issues with my tranny for my Simrad NSS9 Evo 2 for the past 2 years
I have had a HDI skimmer 50-200-455-800. I could never get this one to work very well even when I have had professionals adjust the positioning.
I end up selling this and replaced with the TM150, having same problems with this one. It works well in shallow water (2-13m) even when travelling around 20 knots, when out deeper 30-60m it is pretty much useless unless im doing 2 knots.
Im starting to think maybe the hull is producing air ?? its a Formosa tomahawk 580.
I have been told from a dealer that if I upgraded to a 1KW tranny that it will work heaps better as they are not so sensitive to air.... I have looked at the TM260 but cant afford to buy a module as well as this tranny, thoughts if this will work better than what I have without the module and will this one just have air pass under it too... ( I fish up to 120m at the moment)
Other thoughts was buying a through hull tranny but not sure which one and not sure on drilling holes in my hull.
I have looked at the P79 at this stage, not sure weather the brass one would be a good match for an ali hull

I'm running twin NSS9 EVO 2's

I'm running twin NSS9 EVO 2's with the TM260. I'm extremely happy with the setup, you don't need a module. If I could figure out how to add pics I'd throw some up.
