Got the Clear for HDS5...Where to buy?how much? other options?

[oneyedeer]

Finally saved enough for a decent fishfinder. I got my eye on a hds5. What is consider a great deal? I'm not in a hurry? I know from some threads that every now and then westmarine has it on sell and to price match at basspro shop or vice versa. I know I should get the model with 50/200 transducer. Is this system plug and play? Do I need to purchase additional maps? If so which one should i purchase for Southern cali ocean fishing? Sorry I got lots of questions graduated from m68c

Thanks in advance for post and pm welcome...thanks!
