Lake master chips

My first time with the new depth finder that has the slot for the chip. Are these chips a one time use only meaning once you have put it in your depth finder can it be taken out and used in a different machine? If they can be used in different machines why do you not see used ones for sale. Say you upgrade to the newest release is the old chip you had now no good. Do they come with a users key code like computer programs do so they can only be used by one particular machine?

Thanks for any info.

You can re-use as many times as you want on as many different machines you want. A lot of people have multiple and want backups so they dont sell them. And some manufacturers will buy them back from time to time

Ive bought and sold multiple map chips from a certain free listing site on the internet.
