It’s a great unit, it’s well worth the money. The 7 inch display combined with down imaging produces incredible detail.

So far this unit has been a disappointment for me. I’m not getting any readings if it’s deeper than 250ft even though the broadband sonar is supposed to reach the depth of 600ft. They sent me a new transducer, if that doesn’t work I’ll have to de-install and return the whole thing. Needless to say I do not recommend buying this unit.
