I posted a while back along with others having problems with losing depth at higher speeds. I have spent some time experimenting with mine on my 1850 tyee, as I was losing depth at 25 mph. With the transducer mounted on a strip of plywood, I had a friend run the boat while I laid over the transom doing the adjustments. Due to the rise of the transom, I found the best location to be near the outermost edge (starboard) of the transom where the bottom of the hull is flat. Any other location, due to the angle, would lose bottom on the slightest turn to the left. I lowered the bracket and angle in each place in-between, but could not get above 30 mph with depth reading. The outer edge got me to 42 mph, then started to lose depth.
After discussing this with an engineer from zercom, I got some more advice on what to try next. Due to the wide beam of the -ducer, he suggested (after uploading the super-user mode) going into the (x-mit length) function, and changing it to HIGH rather than auto. Also, changing the (beam) function to NARROW, instead of auto. In the meantime, he sent me a different transducer to try, which I just recieved today. He said it should help with higher speed readings but it may show less of the arches while stationary or moving slow. I will give both of these recommendations a try tomorrow and post back my results.
I mentioned this site to him and he had heard of others having problems here, but did not want to post anything until there was a definite fix. So at least they are working on a fix.
Take care,
Brad
