Long-Range Remote Control Bownet Release. Tested to over 1 mile line of sight range. The box is weather sealed against rain or snow. Very fast action release. The antenna is flexible so that birds flying past will not upset the mechanism. The setting height is adjustable for very low profile setting and works extremely well with my low profile bownets. It will work with most bownets having tubes as large as 3/4″ diameter. It takes 8 standard AA batteries in the receiver box with plenty of power for 100 plus releases and a long standby time of several days. The transmitter takes a single 9 volt battery and has a very long lifespan. Batteries are included. The shipping within the US is $15.00 or FREE for this item if you also order a bownet at the same time in which case you will only pay shipping for the bownet. International orders, please ask for a shipping quote. For a link to the youtube video demonstration, click ‘Noble Falconry videos’ at top of the main page and then to my youtube channel.
