Combine Sonar & GPS or keep seperate units?

[Cove]

I need to buy a new sonar & wonder if I should get a combo Sonar/GPS. I have a decent simple GPS unit (no maps etc)I can mount on past boat.

Question: Should I consider a combination Sonar / GPS unit? I read about these but can't quite visualize how this would work and if it would be any advantage over seperate sonar and gps.

I have the Lowrance LMS 240 on my boat. now the LMS-320... Couldn't be happier and use the GPS all the time. I think its convenient to have them both in one unit. However I also have a hand held that I use for ice fishing. I can transfer from the boat unit to the hand held. I would say if you cant afford the GPS/Locator unit then by all means you can use a hand held and a locator seperate. But if you can afford it, I think its a good idea. It gives you quite a large GPS screen when needed.

Thanks ExudeDude,
The little screen on the hand held is a little cramped to say the least. I had not thought of that.
