Internal or external GPS

which is better to have, internal or external antenna. Thinking about getting a humminbird 978 si are they worth it. Also anyone know of a discount place cheaper than BPS
thanks

They're pretty much the same price everywhere, but if you want to save on tax and shipping buy at Tackle Warehouse. If you buy from BPS you have to pay 7.25% In. tax

An external is required if you have a top. If you have an open Bass boat, an internal makes more sense as there is less to mount/wire/hookup.

Go to BBC.com & go to the Humminbird gps froum & they will answer any ??? you may have. They know there stuff & the is some great SI info & pictures. There are also sponsors that will give you a pretty good deal on the unit your looking at purchasing & any problems they'll take care of you.

Not sure about Hummingbird units, but Lowrance units I am familiar with, the external antenna works better, stays connected better, more stable.

i have one of each and they both work good my 1197si is external and it works great, now the 787ci is internal thats in the dash and it takes a few seconds longer for the gps to kick on for it to get a reading but it still works great. but i think its becouse its in dash if it was exposed it would proubly pick up faster but it still dont take that long for it to pick up.

I will point out one problemwith GPS. If the receiver goes out on an external you can just buy a new antenna. If you have one go out in an internal i would guess that you would have to send it in for repair. Just throwing that out there because i recently had an antenna quit working on my lowrance.
