Just off the top of my head, I recall seeing ads about a year ago for a short range radar for about $700. However, when I went looking for one to "see, feel, touch and hopefully try", all I could fins were the transmissiter/receiver in that price range, with the display unit being close to an equal amount or a minimum price range of approximataly $1500 to $2000 for the entire unit (Tx/Rx and Display unit). Did I somehow misunderstand the announcements or have dealers chosen not to stock the lower priced units? This would be for use on a Hunter 27, but i don't think that is particularly restrictive to itself. I seem to recall the radar ranbge being around 16 miles, which I assume would be the beam and return, and not a diameter? One specific question about ship board radar. I have heard that in a dense fog that they are useless in that the signal cannot penetrate dense fog. Is that true? Would that be equivalent to a term called "Inversion Layer", as might be found in larger search type radar units? Thank You, Bob E s/v Second Nature
