I've used Tacktick yachtmaster system for about 5 years- the knotmeter paddle is extrememly prone to jamming after it rains if lots of small sticks are around, and if you aren't careful the through- hull can be damaged and leak. You do need to pull the pin and lube it through the paddlewheel upon occasion too. The transducers and through- hulls are easy to get from Airmar- and they are great!(the help) Dave

:: Nat,

:: We have the TacTic wireless system on Moxie and have

:: "brain" portion and they immidiately replaced it, no

:: transducers so I didn't have to change out anything. I
:: would recommend giving them a call to see if your
:: existing transducers are compatible with the new TacTic
:: system.

:: Hope that helps.
