We are back from the Chicago boat show and had a great time! we met and listened to, and learned from a LOT of great sailors, Dawn Riley, John Rousmaniere, the Pardeys, etc., Lots to take in, it was very worthy, we also met with the Garmin reps and found that they were quickly able to direct us to the unit that would fit what we needed. here it is..drum roll..Jim had it right, the Garmin echo map 50 series, priced at about $550. has an internal antennae, is viewable in the sun, waterproof with cover and U bracket mount, all software loaded, it also updates 10X a second! and they suggested we get it on Amazon, no tax/free shipping. Now all we need to do is get Maine sail to come by and install it, we will provide the beverages!
I will probably make the mount for the edson binnacle like Long did, That is a nice design!
Anyway, thanks for all the input, I will let you know what happens!
