Getting a Garmin Livescope

[Kspilot]

I'm told not to connect the Garmin to the cranking or trolling motor batteries so I seen a battery at Harbor Freight $50 that is for mowers and motorcycles,it's a sealed lead acid that is 12 volts and 166 cold cranking amps,how well would that run my GLS10 and 93SV?

Not sure where you are getting your information.......you can most definitely hook it up to your cranking battery......there are lots of guys that do that.......now as for troller batteries, you can but you do have a chance of interference but do it with a step down regulator or what ever its called as LS cant take 36v.

I was told it would run my battery down and possibly not get my motor started but I don't fish a whole day usually 5 hours a fishing trip.

The Garmin just don’t use that much power especially considering your average use

Who told you not to connect it to the cranking battery? That is how the majority of people have it set up.

Connecting to the cranking battery is the most common approach. Just make sure your cranking battery has sufficient power/capacity and you will be fine.

Hook it to the cranking battery and make sure you display the voltage on the screen. When it starts to get low crank up the big motor and go for a ride.

I have livescope plus 4 graphs... 3x12" and 1x10"... all run through my cranking battery... have never had an issue

Can I connect my positive and negative to the fuse block under my dash without running wires back to the battery? The black box will be about 4 ft from the fuse block.

[fishin couillon]

Yes you can.

Why spend that kind of money on a graph set up with livescope to only get a cheap $50.00 battery from harbor freight sheez?

[Kspilot]

Thanks! I will eliminate the need for #10 wire and just connect to my fuse block which has 2 empty connectors.

The 93sv uhd and black box draw about 2a per hour.
What starting battery do you have and are any other graphs or accessories attached?

I have a Proguide Battery and it is 800CCA and 1000 MCA,I have a Lowrance Hook 5 that is connected to the fuse block right now but no other graphs.
