My friend has a Simrad EQ 42 [I think that's right] and when ever he goes like over 10-15 mph, the screen freezes. He says it's the way the machine is, I disagree. Any thoughts? Oh, once the speed drops, the screen starts working again.
Definitely something wrong, probably losing bottom with marginal transducer placement.<br /><br />Fwiw, Simrad is at the apex for quality marine electronics, bar none. They excel with both hardware and software. And you get to pay a whole lot more money for it, too. Simrad has good tech support, when your friend gets tired of the way it is he can give them a call and get thing sorted out.
