Doug,
I have an Airmar CS4500 which was installed in 2013. Airmar has newer models (ST800, ST850, UST800 & UST850). It is through the hull and when viewed from the outside looks like a depth transducer. See: http://www.airmar.com/uploads/brochures/cs4500.pdf for what I have and http://www.airmar.com/productinfo.html?category=MT <http://www.airmar.com/productinfo.html?category=MT&name=Marine%20Transducers> &name=Marine%20Transducers for the newer stuff.

If so what model is it?

It accurately gives speed readings through water to 0.1 knots. GPS gives speed over ground and isn't as responsive as sensor.

I believe that it measures speed of the boat instead of speed over ground which is helpful when you are trying to judge movement and sail trim versus how fast the tide could be moving the boat. I know there are other sensors now that measure without the paddle. > On Sep 14, 2018, at 9:03 AM, Dan via CnC-List <cnc-list@cnc-list.com> wrote: > > Hi all, > I'm doing an overhaul of my electronics, and I have a general question for > those of you who have been through this before - Are the classic Padwheel > Speed Measuring instruments still worth keeping or have they gone the way of > the Steam Engine? > > I'm pretty sure most Depth Transducer readers now mathematically calculate > your speed from comparative readings, and just about any GPS device including > your phone will give your speed through any plotting software...
