I will never buy Lowrance again. I had an Elite 5dsi on my last boat I bought new. Hated it. Showed fish as tiny specs slightly larger than pieces of pepper. A friend had the same unit and it was exact the same, so not a problem with my unit, a problem with the model. I thought maybe it was a problem with the DSI line. I now have a Lowrance hds7 gen2 and I don?t like it. Has a new transducer and doesn?t show fish when I know they are there, like Kokanee schools. Just bought a Hummingbird Helix that I have yet to use, but always had great luck with them in the past. Cheap, simple to operate, durable. The Lowrance is now only my navigation screen. I know guys that dig Lowrance and have hds10?s and 12?s gen 3 and I?ve fished with them but would personally take a hummingbird 7? over them any day. I want a fish to look like an arch and that?s it.
As for Garmin, my fishing partner has 2 in his boat linked to closed array radar and all that jazz with an Airmar razoo transducer. Biggest screen I?ve ever seen. Can?t ever get them to show fish as arches or fish symbols. Or anything else for that matter. I?m pretty well versed as how to operate all of them and have done tons of research on his and mine and haven?t gotten desirable results. Hummingbird stuff is cheap, easy to operate, and works well.
No experience with Raymarine. Also no idea why my apostrophes show up as question marks.
