Same problems here.
At Ww's Brookvale they got a display model hooked up.
I spied on the Axiom 7" but too complicated for my needs. Pricy too at $1300+
Also checked the 7" Dragonfly which l like with the CMap, NOT Navionics. $800
5" screen too small for ageing eyes.
The only question is the transducer. Transom mount or hull mount? It comes with the transom mounted one but it does not IMO, suit my skeg type hull.
The hull mounted one has a weird shape not like the old round ones, would need sculpturing the hull to fit it snug. And it is 500 bucks plus haul out and fit.
Next week l will talk to Raymarine about it, see what they say.
