This xterra 70 came up on the local buy swap for $200ono an was wondering if it would be a good buy or not just for a first detector to muck around with? Or better to save the hassle and get a better one. Also what's the things to look at when buying a second hand detector?
For $200 or less, an Xterra 70 would be a great first detector, IMHO. To familiarise yourself with the machine, you can download the manual here:

Things to look at? As well as general wear and tear (scrapes, scratches, etc), check for frayed/split cables, cracked casing, damage to LCD area, signs of battery leakage in battery compartment, cracked coil cover, cracks or breaks in coil mounting brackets.
Test the machine, preferably with fresh batteries (4 x AA - take some with you just in case). Does the display look crisp and clear and are all parts of it functioning? (The manual will show you how it should look). Put a couple of coins on the ground and see if it detects them.
If there are no major problems with any of the above, it's time to start negotiating.
If there are minor problems (fixable or cosmetic only), point them out to the owner and factor them into your offer. Good luck!
