I am looking at buying a used lowarance lms -334c just wondering if there a good unit. I mainly want it for navagation i curently use a hand held h20 with a lake master chip. I am wondering if the use a external antena.

I have one and don't like it. It's got an internal antenna and constantly loses satelites.

Thats what i have heard that they lose signal. I have also been looking at a 337c lowerance but no antena with it. I wonder if the 337c is any better.

The 334c has an internal antenna - it's a first-generation internal antenna unit and the shielding was not good enough and caused interference which caused the unit to not hold a signal all that well.

The 332c has an external antenna and holds the signal well, you shouldn't have any problems with that gps. It might be hard to find an antenna for it now though.

The 337 and 339 were dual frequency versions of the 332 and 334 --- the gps in the 337 will be the same as the gps in the 332, and the gps in the 339 will be the same as the gps in the 334.

Can only speak for myself but I use my 334 in my boat,truck and snowmobile and fourwheeler in the winter and have never have a issue with losing a GPS signal. But have had issues with it holding bottom signal on the sounder part of it when I updated the software. Solved that problem by reinstalling the earlier software for summer use.
