Waterproof beach and diving detector suggestions?

[Lasivian]

I live on a sailboat so I would rather not carry a separate diving detector if I can avoid it. But if it means my beach detector functions would suck I'll buy two.
I'm not likely to ever dive below 100'.
I would like to keep things under $1000, but that's negotiable.
I would like to have lithium batteries rather than only alkaline sizes.
Thanks.

I’ll give my dealer a call Monday & find out why I’m being charged for the water kit accessories.

Maybe the water kit accessories in the YouTube videos where order separately & put all in the same box.

I just spoke with a dealer & the water kit accessories are extra & do not come with the Deus 2 but when ordered can be packaged in the Deus 2 box.

For diving with the XP Deus 2 you will also need to order
XP Deus 2 Aerial Antenna, $24.90
XP Deus 2 Remote Control 20 Meter Waterproof cap [red], $3.90
XP Deus 2 Remote Control Wave Guide, $32.90
XP Deus 2 BH-01 Bone Conduction Waterproof Headphones, $69.90.

Update…. I just spoke with my dealer and he said that the aerial antenna & waterproof red cap does come with the Deus 2. So I had removed from my order . He said as far as the Remote Control Wave Guide he’s unsure if it comes with the Deus 2.
