G'day,

I bought one of these units in a combo pack with a electric motor for $430.

I think RRP is about $240 for the sounder.

They do work and as I use a kayak it was better suited then a fullscreen unit. The tranducer is just tied to some leader and sits behind me untill I want a look under the water and I toss it out.

Hope this info helps.
Doomy
