Every year I fish with one of the best Lowrance pros in the business, Bruce Samson. This year I was on his boat and he had two of the HDS-10's one of the 7's and one of the 5's hooked up - he also had a laptop wired in the mix, sidescan ducers and underwater camera......this guy knows the bottom of the lakes up in the midwest like nobody else.
As long as you are not wanting to run a radar - I think you will be very happy with the higher end Lowrance products.
If you have any specific issues or questions Bruce is your guy and if he is not in a tournament or prefishing - he would be happy to answer any tech questions you have. He does seminars on electronics in the winter too.
feel free to email me if you need his info.
