Livescope

[Danny Lang]

A larger head unit is the same as larger display screen. You will hear people say get the largest screen you can afford.

Thank you sir, did not know the lingo.

"Myself I'll upgrade head units before i upgrade transducers unless i get an absolute steal on a 34."


This is a very good question. Would you rather upgrade to a LVS34 or a larger head unit.

I don't have a problem with what i have so i'd opt for a bigger head unit like i said unless i got such a unbelievable deal on a lvs 34 a person couldn't pass it up which ain't to apt to happen.

Do I need to add another battery for this livescope system?

[Les Young]

Danny, I added a lithium battery to my drivers side rod locker strictly for livescope, but you don’t have to.

Danny, You might want a dedicated battery just for your Livescope. If voltage drops very much at all it presents a lot of problems. But, equally important, is the size of wiring you use. Especially if you're running any distance. I ran an 8 gauge wiring harness from Bass Tank the full length of my 19 foot boat. I also have a dedicated 100AH Lithium battery to run 3 units and 2 Livescopes. This works well for me but in you're case I would at least run 10 gauge wire and a dedicated battery of some sort.

Garmin will tell you it is ideal. However, my experience has been it is not needed. I run my 93SV, Livescope and starter for my 9.9 all on a 35AH AGM battery designed for an electric scooter. It lasts long enough for me…after about 5 hours of cranking up and live scoping the voltage may drop into the 11V range, but it still works. It is said this can cause interference on the screen, but the livescope is always somewhat fuzzy anyway if you have the gain cranked up to see little jigs as I do. Good luck and enjoy the new setup!

I currently have a standard 12v marine deep cycle battery. I will be getting a lithium battery when it gives out because the weight difference is huge and the price difference is not that much.

I didn't and ran it to the cranking battery, all other electronics run off the trolling motor batteries. I did run 10 gauge wire from the front of a 19 foot bass boat to the back and no issues so far in second year.

Try running a 175 Johnson a helix 9, a helix 7 & 2 aerators on it & you might change your mind. I have a buddy with 2 helix 9 & megalive & he gets low voltage message every day if he fishes all day & that's after he let the local dealership talk him into putting a supposedly better battery on it. As long as he runs to charge regularly he can get by but says he's going to end up with a dedicated battery for his megalive too. He's also had interference problems with them all on the same system. Most problems & quirks with either of the 3 different ffs are because of dropping amperage. It does seem like megalive is more prone to get a little crazy compared to the other brands though.

Dedicated battery for Livescope for sure. Only trolling motor on trolling motor battery or batteries. Be ok to run pumps, lights, etc. off of the cranking battery.
Foote note: As others have said the correct gauge wiring and shield everything.
Keep all wiring for Livescope AS FAR AWAY from trolling motor wiring as possible. Shrink tubing on all connections. I bought a 50 foot roll of the corrugated shielding and every wire on my system is covered.
Do it right the first time and don’t cut corners.
My way but I’m kinda OCD. Lol
Good luck.
