i just installed the to33 system, very easy to set up, granted the display does require power, but not having to run extra cables up the mast was well worth the little extra in cost

The RayMarine engineers told me the units are the same. (Ray owns Tackick now) It is an effort to up-sell to a more expensive unit. I bought the 033 and am having it connected to an E7 chartplotter.
The Ray engineers have been very helpful at both the boat show and by phone.
