A solar powered unit cycling three deterrents automatically: an ULTRASONIC phase of 3 minutes sweeping 16 kHz to 30 kHz then randomising, an AUDIBLE phase of 3 minutes through two 20 W speakers, then a 7 minute rest, repeating all day; startup is a 6 kHz tone for 3 seconds. Powered by an integrated solar panel and a 12 V 5 Ah rechargeable battery, with 4 ultrasonic emitters and 2 high brightness LED lamps (4 red, 4 blue). Manufacturer stated sound level is 120 dB. Intended for large OPEN sites with nothing to fix a barrier to: orchards, farmland, yards, grain stores, ponds, substations and airfields. STATED LIMITATIONS: it is a scare device and birds habituate, so it must be moved and switched off out of season; it produces real audible noise, so neighbours, stock and local council noise provisions must be considered before purchase; high frequency sound does not carry far or turn corners, so the ultrasonic phase is a supplement rather than the main effect. Two marketing figures were DROPPED as unsupportable: an advertised 130-180 decibels (contradicted by the manufacturer's own 120 dB specification, and a hearing hazard rather than a feature) and an advertised solar panel efficiency of over 90 per cent (real panels convert roughly 15 to 22 per cent). On a building with ledges, spike strips cost less and work permanently.
