High wattage unit, full colour 5in screen, yeah it doesn't like batteries, lol! It also doubles as the graph I use on the bow of the boat hooked up to the US2 on my Terrova during the softwater season. To me its a perfect compromise.
You gotta remember that these features are great, but they eat battery.. My 5000W HB 747C will give me maybe a day and a half on the ice on a full charge (This is why I carry two batteries with me all the time)..
You can see everything with a graph. I can mark a XXXS swivel in 130ft of water
Humminbird for sure if you just wanna turn it on and go without worrying about 1 million settings, lol.
No need to take the boat off, jack up the trailer with the boat on and put it on stands. You can move the axle around all you want if it's up in the air. Shouldn't take you more then 5 mins to see if there's a problem with the alignment.
