GB- I'll give you $30 if you show me how to use it
.I'm also leaning twords the Garmin 240. Its the best deal on a 240x240 that I have found. BassPro.com has it for $279.99. This boat is killin' me - but well worth it. I will take that 315 off your hands if you want to sell it, let me know. Mike I will be calling the shop for the 1100 and chemicals-thank you
