That's part of what I really like about the HDS system. You can buy it in pieces since it's a modular system. I bought 2 HDS 5's when I had the money. Used them for several months as is, while I saved for the LSS-1. Now I can watch the DI/SI on either unit, and saved money over buying 2 full price HB units. Now if I decided to add a sounds system, I could buy the sonic hub from lowrance and connect it to the network, no problemo. I'm not made of money, so this was a great way to get quality units without breaking me off in the wallet. I'm also not bashing HB for requiring 2 SI units in order for you to share SI/DI data. For some that's the way to go, and there's nothing wrong with that, or the HB units.

Like most on here, we pay our own hard earned money and don't have the companies giving us free units, and paying us that way to tow the company line and say all the right things. If we cut the crap about bashing customer service, and really get to the nuts and bolts, we can help inform people about the units.
