I did a beer can chicken. Fresh tarragon and seasoned salt under the skin. Steamed a big batch of asparagus. When there's some room, there's a salad waiting for dessert. The chicken was well above average.
My two cents: A 24v system should be plenty unless you fish all day tournaments in a gale. I am shopping a new troll motor and the Ultrex is my second choice. When The Ghost comes out in a longer shaft I will buy.
Battery advice is all over the map. Some advocate Optima. Wrench says don't spend that kind of money and simply buy new batteries every year. I buy Interstates and replace them every other year. Never had a problem with that system so long as you keep them charged.
I have had Lowrance, HB, Simrad, and Garmin units on my boat. They are all different and all excellent, but If you go with the Ultrex, go HB and link your console and your bow. Personally, I would buy the built in Mega DI.
Remember, my advice is worth what you paid for it.
