Im chasing a combined unit for the kayak. I need a through-hull transducer for the sounder, and an inbuilt antenna for the GPS. Whitworths suggested the Navman 5110 as the cheapest way to do this in one unit. Basically Im in the dark here, I dont know the quality of the Navman, and I dont know what else is available.
The Navman looked fine to me, not too large, removable cables, inbuilt antenna, and pretty simple. Also the price is below $1000, which is good. I can mount a 12V motorcycle battery inside the hull no problem, and run the cables through the hull.
Any thoughts from the watery Brains Trust that is Ausfish?
