Vintage Fish Finder Worth Keeping?

[Utahbill]

Here,s my problem. I am deep into ice fishing mania and would like to get a new fishfinder. My wife is not excited about the prospect of spending even more money on fishing gear. I have a old Bottom Line TBL 100 that I used a few times years ago. I'm convinced I need a newer better sonar unit to replace the old bottom line. How ever if the bottom line is still useful I will concede (at least until next season)[]

Bottom line is this old fish finder trash or treasure?

Thanks.
