I am considering making the plunge. I have two concerns that is holding me up and hoping to hear from some experienced users.

1) I am leaning towards the 798 because of the cost difference in it and the 900 or 1000 series. I am concerned that the small 5" screen being too small making it difficult to see the details of structure and contours. I am sure the learning curve is challanging enough with a larger screen SI unit.

2) I regularly fish an area that I must travel thru a stump filled backawter area to get to. I am concerned with the larger ducer on the SI holding up thru the abuse.

Thanks in advance for any and all input.
