Ok been using hummingbirds for the last 30 years.Like them and had good service out of some of them. But still hate that when spider rigging in hot weather or winter. It will not show me moving unless I'm going faster then what I fish. So have to use my cheap hand held Garmin. Also to have SI on all three, I have to buy higher priced units to pull this off. Hate moisture in units and this has been an issue the last 10 years.

So thinking about going with Raymarine where I can buy 2 units and use a tablet for the other unit. Also buy Raymarine’s CP200 CHIRP SideVision Sonar module and run it on the other unit also. Plus have Bluetooth to connect to tablets and use the Tablet for the GPS.

Or go with Garmin and try out there units?

Or Lowrance units?

I will have to say I like that with the newer Birds I can make my own maps and stuff. But the moisture issue just burns my butt along with the GPS not showing movement when you're around .2 or .3 MPH.

Plans are to spend around $4500 to $5000. on electronics and will have them set up to swap between boats. So will have to also have 2 mounting kits for each unit..
This will be for our Retirement and I hope to be able to fish 4 to 6 days per week them. That is a little over 3 years off. So may just go cheap for now and see what comes out between now and then.
