Older color charplotter that takes Lakemaster chips?

[Hookmaster]

I am looking for an older color charplotter that takes a Lakemaster chip. The H2O handheld is getting a little hard to see. I guess it would be either a Lowrance or Eagle brand. I am not ready to upgrade to a Humminbird gps/graph combo and buy another chip although that would be nice. My graph now is a Humminbird 777C and works fine. I am looking for model #s so I can search on the internet.

I use the Lakemaster chip in a Lowrance LMS-520 and LCX-28. Those are about 7 years old now and would think they could be had fairly cheap on the used market. Both are color. A 522 or 27 would work too.

Amazing that the lms5xx units are like 300 bucks on the large auction site.

Really? Maybe I should sell mine. Ha!
