From what I've been told a few of the features are very useful, but I've not looked it up for myself, but check this out, you can take the sensitivity down to like -1 as you would in a storm, however if you were snag fishing you'd still want plenty if beeps to get your attention so you'd turn the beeps up, you can't achieve that with the older ones. Also adjustments by remote instead of having to go outside when it's [censored]ing down 👍
