They do if the transducer is installed correctly. But sometimes that is hard to do.
You also have to consider that many flashers only show a depth indicator (not a digital depth number), have less sonar signal processing to do than a chart type sonar unit and don’t have to use any processing power to update a GPS track and/or map either. But a lot of times it’s like Barnacle Bill said: “They do if the transducer is installed correctly.”
Can't use the GPS refresh as a reason..:DQuote:

This is why I have a electromechanical flasher. No dummy (microprocessor) in the real time loop.
My boat holds 2D Readings over 70mph. How? Transducer Location. Location. Location.

Went for a ride with a buddy in his Cessna 340 few weeks ago. He just got it restored and took me for a show and tell. My Garmin did good at 200+ knots @10,00 feet. Wonder what that 1100 would do at this speed and altitude?::p
Forgot to say my Garmin matched the AIS instrument in the cockpit.
