I was dissapointed in reading one of the early responses to your question. Namely, that the FL-18 has a bottom lock feature. Anyone want to buy my FL-8 … It’s time for me to upgrade!
But seriously, I’m struggling with the same question in terms of the LCD and its compatibility with temp variations. I’ve got a Lowrance X-97, used one summer, that I’m in love with and would like to put an ice ducer on it. I’ve been asking around for the past two months and the opinions (few facts) haven’t been very definitive:
* you won’t have any problems
* don’t let the LCD freeze or you will damage pixels and get a garbled screen
* keep the isplay unit in the truck or coat pocket while setting up
* use one of those 4-hour handwarmers, place on the screen while in transit
* LCD is difficult to read in direct sun
I like to run from hole to hole at times and my FL-8 (still for sale) is subjected to the temp variations. At this point I’m not willing to risk my X-97 in those conditions.
