Bass Pro has this g2n unit for $499.97. For those looking for a starter, or a mapping unit. I believe this is a good price.
I have a flyer for black Friday week November 23/29th. It's a Monday only item. Not sure if it's in store only, even so,worth the drive to save $300. Hope this helps.i got excited as i am in the market for this or very similar unit for mapping in the front of the boat. just went and checked and didnt find one. i saw a g3n mega DI for $600
Any unit that utilizes the same frequencies will cause interference. The units can’t tell which one sent the signal. That being said, I run three HB units, two 9s (console) and a 10 (bow and connected to the Mega 9 on the dash). All have chirp and each one will interfere with the others in 2D and sometimes DI (Mega units only with dedicated DI). But usually only in water over 30’. It also depends on the cone diameter. The smaller the cone, the deeper it will go before interference occurs. Haven’t had a problem with SI between bow and transom. Just my experience. YMMV.I was looking at this as well...for the front of my boat. I have an older Hummingbird on the back...am wondering about possible interference between the two??
Or any other manufacturer's unit.
