Sorry for the secondary posting. My upgrade is to give me better detection of debris (including logs) in the Puget Sound cruising waters, as well as to gain my horizontal resolution of close targets. Adding to my previous question, assuming the near-field to far-field transition, how/where would you suggest a mounting that will adequately detect floating debris? If the beam does not transmit on 25 degrees, does this mean I will need to shim it downward to see nearby floating targets? Any bow-rise from cruising speed would benefit from this shimming...but what about the slow, near level pitch in adverse light conditions? Thanks ! Randy Allen Olympia, Wa

Yes, if you ride bow high when cruising, then a rake to the unit to make it level at that plane would be logical, and is often done.
as for seeing logs, the bigger unit will definitley help with that, but i am not sure you gain anything from the rake in this respect, though the rake is good for other reasons. You will have a minimum range as discussed in the book, no matter what, but more to the point, unless it is flat calm you have sea clutter at close range that would usually block such detection at very close range, not to mention that the warning is most use to you the farther off it is.
it might be interesting to see the results of the shovel experiment.
