Used equipment is available and can sometimes be a great deal, but the rapid advance in technology over the past 10 years or so means that there is a lot of obsolete (and sometimes dangerous) equipment out there, even though it may be in "good" condition. Unscrupulous or unknowing sellers offer this "almost new" stuff to unsuspecting buyers. All used gear should be checked by a instructor or other experienced pilot before purchasing! See above for comments on used gear.

No. We only sell new, unused equipment, so that we can ensure that we are offering you the highest quality product that will serve your craft for years to come. We keep any used equipment to offer as "loaner" equipment, to be used by our customers while they're having a unit repaired or upgraded.

Like Radar and Sonar, Ultrasound uses the echoes of sound waves to produce images. In the case of Ultrasound, these sound waves are transmitted through a transducer, and partially reflected back to the transducer by the body's tissue. Human hearing is typically in the frequency range under 18,000 Hz (18 kHz). Bats and whales use frequencies in the range of 100 kHz. In contrast, Ultrasound uses frequencies above 1 MHz (1,000,000 Hz).

HeartScreen America offers affordable, high quality screenings through the use of patent pending protocols and the use of digital interpretive ECG technology found at leading healthcare institutions and hospitals. All equipment performs an internal self-diagnostic check and continually recalibrates for accuracy. Additionally, preventative maintenance is performed on a regular basis.

I probably sound like a broken record, but again I recommend Ebay for an active, if sometimes pricey, selection of Dyna gear. Sometimes you'll have to pay too much, sometimes you'll get a steal; but patience is often rewarded. If you're aware of electronics flea markets or hamfests in your area, give them a look. I've found nearly half of my vintage Dynaco components at flea markets, and they're sometimes cheap just because they're old or have a blown fuse.

One may not make medical claims about indoor tanning equipment. However, phototherapy (or UV light treatment) can be used to ease the symptoms of psoriasis. The treatment is rendered by a trained physician with equipment specifically designed for such a purpose. Many salon operators report that customers who suffer mild forms of psoriasis improve after indoor tanning, and many psoriatics do purchase indoor tanning beds.

Yes. However, the University must be reimbursed for the use of such testing facilities and/or equipment and use must be pre-approved by the faculty member's department head at the same time the consulting is approved.
