so I bought a Lakemaster chip for my garmim nuvi.( I can’t afford a true gps/depthfinder right now) how do I get the most out of it and can you use the chip on your cpu as well? right now, what I see is one foot depth changes on the river.. and that maybe all well and good. but isn’t there more I can do.. plus change the colors to show depth? there are not real instructions with the disk, and I bought it brand new at the local pro shop.
