I have recently made the upgrade. I looked at the helix5 and really like the unit. The only downside is that I had to use Ethernet connections from front to back and that is not available on the helix series. I went with the 899si on the console and found a used 998 on here for the bow. I stayed with HB for ease of use. Price also was a consideration as the lowrance unit was quite a bit more at the time I got the 899. The little exposure I have had with lowrance had me going thru me yes quite a bit and I like the scroll thru feature of HB once you turn off the functions you don't use. If you come to camp this weekend I would be glad to give you a test drive.
