I was forced to replace the speed log impeller on my
B&G Hornet which worked reliably, accurately for 30 years... with an Airmar DST800.
It's been in the
hull since April 2015. I am so far not enchanted with it for the following reasons not in order of importance:
1. It all black, plastic and where it's installed (old
B&G hole) it dark and difficult to see. ( I have the same issue with my car FOB which is black and hard to see when I drop it (often) in the black interior). Why not white????
It has a insert direction "arrow" which is a raise graphic... very difficult to see as well.
2. It seems to get clogged rather easily... more easily than the B&G impeller. I had the bottom scraped 2 weeks ago... cleaned a very very fouled impeller... which worked for one weekend.... and stopped. When I removed it for
inspection... there was barely anything on it... but the impeller can move laterally. I wonder if this plays a role???
3. The accuracy seems odd to say the least... hard to adjust from the Hornet... either too fast or too slow with consideration for the
current. I've tried changing the "damping"... maybe I haven't found the best setting... Is this a B&G Hornet problem or an DST800 one?
I suspect this is a common speedo.... so I ask what is the experience of others and what instrument is is paired with?
Can it send data to the Hornet and a B&G T7 at the same time? Does it have a temp output? If so can this be displayed on what stand along instrument?
Thank you!
