Lowrance hooked me up
Lowrance fixed me up just fine.
Just wanted to add here that I did finally send in my unit for evaluation and repair. It works very well now, it was indeed a flaw with the internal antenna. There was no charge and the turnaround was quick, about a week or ten days, with the to/from shipping time.
Now it locks on in much less than a minute and I get many more birds locked and generally WAAS lock when handheld as well. This is what I'd expected it to do. Now it does.
Lowrance staff were helpful and friendly, though they are quite busy so getting ahold of them means waiting around a bit and some callbacks needed. They always called when promised, which is a rarity these days.
I'd buy another Lowrance product tomorrow, two thumbs up from me.
