Humminbird Questions

So putting together a few ideas for some upgrades for the boat over the winter/spring and I’ve figured up my ideas if I go Lowrance, but I also want to look at Hummingbird units (esp. after seeing the pp on that new 1199 SI), which I don’t know nearly as much about. More or less building back from ‘scratch’.

Here are my questions:
1) I heard the SI duecers can have trouble keeping bottom on plane (much like lowrance SS duecers) and that you should have the high speed duecer also, is this true? I assume the high speed would be an add on purchase and not included with any of the SI sonar units?

2) Does humminbird network connections share gps cards (lakemaster), so if I have 2 birds I only need one set of lake chips?

3) Can, lets say the new 1199, be networked with an older 757 that I have and share waypoints/maps?

4)Anyone who has ran both Lowrance and hummingbird care to share you thoughts on the big differences, if any?

Thanks

I can answer your first two questions.

Yes, you will need a high speed transducer. I’m pretty sure it is an add on item.

No, you can’t use one gps card for both units. You have to buy two.

That sucks, so to have 2 bird units I need to add another $250 into my budget for them both to have LM chips(WI+MN). If I go bird I will probably keep my 757 up front and use the navionics chip for now anyway, but would be nice to be in th bow looking at the same map as at the helm.

No it can not be networked

My HB SI transducer reads bottom just fine at higher speeds (up to around 60 in a bass boat in calmer conditions). It has more to do with transducer placement than the actual transducer itself. However, if you get the SI tranducer up an out of harms way (which I would recommend after breaking a couple of them) then I would definitely recommend getting a high speed…

I have the 597 ci HD DI and have read conflicting posts about using the xi 9 20 ice transducer for ice fishing. One post indicated this could screw up the down Imaging ability of my unit

My hdsi transducer reads at full speed in my Skeeter WX1850. It’s all about placement and taking the time to find the sweet spot on your hull. Initially i had mine mounted up on the step…. Hated it in this “safe” position.
