|Comments||We are down to our last SL-70 Transponder. This radio looks great, but it was certified with a European Form 1 in 2014, so we discounted the price.
If you can accept this older certification (with the same 90 day warranty), you can save some money.
If you would like a fresh 8130-3, we will be happy to process it through the shop for $100 extra.
The II Morrow / Garmin AT Apollo SL-70 Transponder offers comparable performance to Garmin's GTX-327. Garmin purchased II Morrow / UPS AT and ultimately discontinued the SL-70, but at one time these radios were direct competitors.
The SL-70 is a very powerful transponder. It produces a minimum of 250 watts of transmission power, and the manual states that 325 watts is the typical output. This ensures your position and altitude are noted at very long range.
In the interest of reliability, the SL-70 automatically begins its self-test function if it has not been interrogated in the last 30 seconds.
Additionally, the SL-70 offers an innovative Altitude Hold feature. When you reach your assigned altitude, press the "Hold" button. You may set an altitude buffer between 200 feet and 2500 feet, in 100 foot increments. (The default is 300 feet.) The SL-70 will alert you if your altitude drifts more than the allowed buffer.
The SL-30 is only 1.3 inches high, offering placement flexibility.
The SL-70 features:
