Garmin vs Lowrance

[Riccochet]

I have had both Lowrance units and currently run Garmin units. Is it just my experience but do all of these units loose the bottom when running across the lake at 50-65 MPH?
It's really annoying!

My humminbird with shoot-thru transducer did a much better job of reading at speed than my Garmin does with the GT15 mounted in the same exact spot. Same boat. That's my $0.02 on it from personal experience.

Sometimes the Garmin will read at 50+, sometimes it won't read at 30 and the depth just flashes. Water conditions matter not. Could be glass and I won't get a reading once on plane. Come off plane and go again and I get a great reading. It's hit or miss. Annoying.

Exactly the same experience I've had with Lowrance and Garmin.
