I have 2 of the Striker 7SVs on my little boat at the lake house and they are great units for the price. Had them since April.
You said you didn't need GPS/Chartplotting, they have this but not Mapping.
One other thing on the Striker units, if you manually enter settings for each screen setting, like contrast, depth range, side imaging range, etc..., if you turn the unit off when you raise the trolling motor to move. You will have to reset everything back up on unit restart. I just leave mine on between spots to eliminate that problem if I've manually entered anything.
They work great in Auto also!
