Your welcome. That's the 2cnd generation model. First generation did not have chirp. 3rd generation has chirp and touch screen, they're called plus units. There's also the striker series, they're cheaper yet. Two generations of those also. Stiker plus, 2cnd gen, have quickdraw mapping capabilities (can record 2 million acres i believe). Both of the stiker series have base maps that you can store waypoints on. Both the striker and echomap units use the same transducer and have the same screen quality. The main difference between echomap and striker is the mapping.
