I’ve been a Lowrance guy forever but I’ve had quite a bit of experience with Humminbird. James has birds rigged on his boat and I can offer my personal opinion.
The sonar on the birds is well…not so good. And by not so good I mean awful. In talking with the techs at SBC they say it is vastly improved with the Onix units.
I don’t know what exactly the problem was but I had Onix units go completely AWOL when I was out fishing…it would make me a touch nervous to sink a bunch of money into it.
I have only had the opportunity to play with the new onix units a handful of times out while we were fishing and struggled with the user interface. It seemed quite dense and convoluted as compared to the Lowrance and previous versions of the bird even being well versed in the old humminbird (2014) units.
They say the side imaging is excellent on the new units.
If you’re a guy who likes to use side imaging a lot I wouldn’t shy away from the Onix. Also, she’s slow as a dog. All the way from starting up the unit (3min) to loading and navigating screens.
Personally, I would continue to run with the HDS hands down! Rock solid sonar and easy interface. The down scan and side scan are no slouches either. It’s just a tried and true system.
