1) - The Simrad seems too small and fiddly to use on a RIB - we used one on our course last week and it was bad enough in the classroom
- Icom have nice big displays - and buttons
- I am looking at the 401 VHF unit which is about half the size of the 503 in the picture with the same DSC unit
2) - People on this forum seem to have had problems with Simrad - somebody was on their 3rd handset
3) - Icom give 3 year warranty
4) - I've always had Icom with no problems (touch wood)
