OneCast Fishing

So I use traditional sonar at the bow. The reason is all sonar works best on the move between 3-5mph. If you move slower than that the image is distorted. Even with traditional sonar you see long lines across the screen rather than arches, unless a fish swims through your sonar cone; then you will see an arch. You are rarely moving that fast when fishing up front. Additionally, both SI/DI do not have a coverage cone like traditional sonar, which is a cone. They emit signals at a larger angler but what they see is an extremely small slice. Think more of an extremely thin triangle. If you see a tree on your screen with DI that tree is going to be a lot harder to pinpoint for a cast than if you saw one on traditional sonar. To me its not worth the extra money to have the SI/DI imaging up front. Put that technology at the console and network the one up front. That way you can search for fish and structure, mark the way point, and then go fish it.

I appreciate all the quick replies. I do have a battery charger for the existing marine cranking battery. As for the issues, after about 4-5 hours the electronics give me a low voltage warning and the bow helix will shut off. The motor would still start but I was reading under 10.5 volts. I had been looking at the Optima. Sounds like to be safe I should go with a separate battery for the electronics. Adds a little weight but better than having dead batteries out on the water. Thanks for the all the input.

I recently installed some new electronics on my Triton 189 TRX and all are wired to my cranking battery. I have Helix 7 (.9 amps), x 2 Helix 10 (2.4 amp each), Garmin Echo Map Ultra 126 (3.3 amp) and Livescope System (1.75 amp). I also have a one 10 foot power pole, and the typical other systems that require electricity such as live well, lights, and pumps. Obviously, my current battery (Interstate Marine Cranking 27M-XHD) isn't cutting it and drains pretty fast. I can't get a full day of fishing out of it. What should I do? Is there a large battery that I could go with to meet my needs? Do I need a second battery to only run the electronics? Do I get a second battery and a switch where I could go between the two if one dies? Thanks in advance for the input.
