Well, after hours of comparing the G2 and the G3 online, the biggest difference between the two is the new model has "mega" imaging, and I broke down and bought the G3. Buy once and cry once, right? Price from Idaho Marine was almost the same as online, so just went with them. At least if I have an issue, I can physically take it down to them and have them replace or repair it without dealing with shipping it all over the place.
I figure the mega imaging will be a nice added feature, this boat sees a lot of different fishing spots, I think it will be worth having it. I don't plan on changing this out for many years, so long as it continues to work correctly.
Its installed and looks much sharper and detailed when compared with the Garmin Stryker Plus 5CV it replaced. It also ties into the Terrova quite well! Pulled the tracks I recorded of Arrow Rock instantly.
Bonus!!! The Garmin swivel bracket fits this almost perfectly! Just added a rubber washer about a quarter inch thick to one side of the bracket and she's solid in the boat yet still moves up and down easily enough. Its also a cheaper bracket at about 20 bucks online, and it keeps the unit low on the dash.
Gotta buy an extension network cable for the Terrova next week so I can route it behind the wall up front and under the dash. Don't plan on going out anytime soon, last weekend's trip to CJ for some crappie fishing was good but way too cold!
