The Ameri-King AK-450 and the ACK-E01 are two of the most popular ELTs in the market. Their compact size and light weight make them ideally suited for general aviation.

There is a safety advantage and operational savings realized with either of these ELTs. Because both of these units use D-cell batteries, savings to the owner and a higher degree of ELT reliability can be had by simply installing fresh D-cell batteries every year, during annual condition inspection of your airplane. (The removed batteries are most likely still perfectly good and can be recycled into home use flashlights, etc.)

These ELTs pay for themselves in a few years !!

The table below outlines the various features available with each of the ELTs. SafeAir1 gives a slight nod to the AK-450 because of the voice transmit feature that could be useful in a downed aircraft situation for helping rescue efforts. The "warble" tone of an activated ELT must be located with "DF Steering" equipment but being able to ALSO transmit voice might allow pilots to direct rescue efforts to the scene much more quickly.

For Experimental aircraft, the ELT you choose may be based on how you plan to install the device. Click this button to view actual installation photos in RV-6s.
