Can i connext this straight to my boat battery

Yes, you can connect this direct to battery (assuming it is the normal 12 volt system). A suitable power lead is supllied with the unit. Peter, Hamble Marine.

does this have its own builtin rechargeable battery or is this a separate purchase as i do not have a 12vo;t battery in my boat

You will need a separate power source. If your boat has any other instruments e.g. outboard engine starter motor, or VHF that requires 12 volt battery you can connect your GARMIN to the Sam'a battery. Otherwise you need to buy one. Such batteries also need recharging at least once a month even if you don't use them. I charge mine at least every ten days. Good luck with finding lots of fish.

is this unit rain proof, thanks

Yes, it is rain proof. It is protected with ipx7 ipx7 Suitable:SplashesRain or SnowShoweringIncidental exposure to water of up to 1 meter for up to 30 minutes

wat battery do you need for this item

well i have two np7-12 yuasa 12 volt,7.0ah joined to make 12 volt brought from amazon then a cable from the outboard to charge them but you can go one full day with out a outboard that charges as you have two of these small batteries joined together will last all day no problem but i would not just have one. as i dont think it would last cheers

Farmaweb - amazing

This product is fantastic and works well at depths. But the main thing about the buying experience is that Farmaweb are excellent providing prompt messages and also answering any questions in real detail. It’s been a pleasure dealing with them.
