I have a Lowrance 4800m GPS and a X75 sonar on my boat.
I been thinking of upgrading the X75 to match the 4800.
Now I been looking at the Humminbird 700 units.
Lowrance or eagle have been the brands of choice and I already have accommodating holes in my transom for Lowrance hardware.
Humminbird looks very good now days. What do you guys think? Would a Humminbird be a better choice than Lowrance now days?
I think you’d be happy with either Lowrance or Humminbird. Both are very good. In your case, you already have a Lowrance GPS so it might make more sense to go with a Lowrance unit in the event that you decide to network the units. If I were in your shoes, I would probably get a Lowrance LMS-520C with 200khz transducer and without GPS for around $450. You can run it as an independent sonar unit, or you can network it to your globalmap so you have GPS on both units. That may come in handy if you ever had the Globalmap malfunction while you’re on the water.
If networking doesn’t interest you at all, then the Humminbird units should be considered. If you are looking at a stand-alone sonar unit, the Humminbird 777C would be a great choice. It has a very high resolutions screen and is fully powered at 500 watts. One advantage it has over Lowrance is the dual beam sonar. While Lowrance offers dual beam sonar on select units, they cost a little more and they only offer a 12 degree cone at 200khz on their dual frequency units (their single frequency units are 20 degrees at 200khz). This Humminbird unit offers a dual beam with a 20 degree cone at 200khz, and 60 degree cone at 83khz. You can view this dual beam together as one image on the display, or you can view each separately, selecting either 200khz or 83 khz. This particular Humminbird feature is an advantage for fresh water anglers, IMO.
