Default 2 GPS Units - 1 Boat??

So I'm getting ready to Refit the Boat I'm getting with Newer / Updated Electronics.

I'm already set on getting the Garmin 740S Unit.

Now, I need a Fishfinder.

Should I get a Combo Unit or one that is JUST a Fishfinder?

The 2 Brands I'm looking at are Lowrance & Humminbird. Kinda Leaning towards Humminbird after Reading some of the Horror Stories people have had with Lowrance, but I know, it's an Electronic Item, ANY Brand can have problems.

My Reasoning for wanting a Combo is if the GPS Craps Out on the Garmin, I'd have a Back Up to get me Home.

Does it sound Crazy to have 2 GPS's on 1 Boat or no?

A lot of members on the site have duplicate electronics. 2 VHFs, 2 GPS etc. heck several even have 3 of the same. Two fixed mounted and a handheld.

Almost makes no sense just to get a fishfinder unless u got a lot of space and fish offshore a lot.The 740s has sonar on it already.Which works very well.At the price the 740s is right now I would get 2 of them if u have room.If not maybe a 541s.That way if ever have problems with either one u can always still be fishing.

Yep, if space and your wallet will allow I'd just get 2 with GPS if you're already looking at getting 2 units. Can just have the one setup as a FF and the other the plotter at all times but you'll at least have that 2nd GPS if needed.

The 740 s was on sale a t WM last week for $800.00 , That's a great deal and a great unit!

In my opinion if your going with two units go with matching units, It is a much better look on the dash .

I don't think the Dash or Overhead Box will be big enough for 2 Units together, so I may have to Flush-Mount 1 and Surface-Mount the other.

My boat is smaller than yours and I have at least two of everything any time I plan on leaving the harbor. Mounted i have two combos. and a compass, obviously. Extra Handheld VHF doesn't hurt to throw in the tackle or ditch bag either.

For the cost difference, I just don't see the downside. Unless you need a super badass sounder.

I have run with two GPS/two radios for many years. Usually one of the GPS units is also a fish finder--or maybe I'll have one combo and one pure fishfinder (such as Furuno)...

Here's a pic of my helm. I have an additional VHF montes in my e-box. Two MFD's are very useful. I run cartography on one and sonar on the other...as always have so at on looking for new ledges.

I like having multiple gps' on the boat. I say go for it.

I had 2 gps/chartplotters, 4 vhfs, 2 ffs but only 1 radar on my last boat. We had a problem one year when the military shut down gps for a few hours so neither of them worked. (that was when selective availability was in force and the military controlled the signal)

My boat is a little smaller than yours and I have 2 chart plotters but only one is hooked up to a transducer.

One of the chart plotters can operation on a battery if needed. I also carry a handheld GPS and VHF in a ditch bag. It for some reason I loose my power I still can talk to someone and give them my position.
