Review: Works well if used correctly - My next door neighbour is an animal lover and has always left seed out to feed small birds. Recently she has taken to leaving larger amounts of food out and has attracted seagulls, crows and feral pigeons. Unfortunately she isn't the most approachable person, so I decided on buying an electronic scarer rather than having any confrontational visits with her. To be honest, the reviews of all the sonic and ultrasonic scarers are very mixed and I was not 100% sure this one would actually do the job, but I thought I'd try one and see for myself. I've had it working for 4 days now and it does seem to be doing a good job. I didn't particularly want to scare the smaller birds away from eating in the tree next door, but did want to get rid of the large birds which spend hours on the ground fighting over the dropped seed and then take off and cr*p all over our washing, so I placed the unit directly on the ground facing the tree at a distance of about 5 metres away. I have the audible sonic sound set to "off" and the ultrasonic pitch set at the higher end of the "birds" setting, during the daytime only (off at night). The results are quite obvious and exactly what I wanted to achieve. I've switched it off a couple of times , just to see whether the birds return, and they do come back within a few hours but leave as soon a s it is switched back on again. The small birds such as sparrows still hang on the feeder in the tree but the larger birds absolutely WILL NOT go near the tree on the ground. We've watched pigeons walk towards the tree and suddenly stop still, then fly away without attempting to get close to the seed. Seagull have not even bothered to land since the unit has been active. It hasn't affected the nearby nesting birds and their young, which still tweet in the morning while the parents are collecting bugs from further up the garden, so all seems to be good in that respect.The neighbour has obviously noticed the unit sat on the ground, but has not mentioned it, so that all seems good too! I may be lucky in the fact that I have worked with sonar and so I have a basic understanding of how sound-waves work and are affected by various conditions. I would say that to get best results, although the unit sends a 170 degree signal from the front,it still needs to be facing directly towards the area that needs controlling, it must have no obstacles in the range between the unit and the target and that it will be less effective when it is raining. Thoughtful and careful siting of the unit will give much better results. The photo shows the unit sited next to a garden ornament, facing the tree at a distance of about five metres from the problem area. UPDATE August 2016: I've had this product working in the back garden for 3 months now and here's what I've noticed: 1. It works best if you either change the ultrasonic frequency every week or two, or if you set it to scan through the complete range. 2. It may not ALWAYS be the birds that are the issue, but the people who attract them by feeding them. So, as far as I'm concerned, the problem has now been completely eradicated by setting the audible noise at a level that actually became so annoying to the unapproachable neighbour it forced them to come round and agree to move the bird feeder as long as I turned the noise off! Agreement was reached and the problem has gone. Best money I ever spent!
Review: Pathetic - This item is absolutely useless. I have a rodent issue. I have set the device setting to rodent deterrent. This immits the most unusual and useless cycle of sounds once the sensor is trigger. Completely audible to human ears, the sounds of car alarms, house alarms, and 2 birds of prey do not deter or scare rodents away. Mainly because they're not completely stupid and are very intelligent creatures. Rats especially need some form of ultra sonic sound to be uncomfortable so the above sounds of generic city dwelling mixed with a field are pathetic. For the price of this item as well. Its very hard to click the back panel back on as well. It's weatherproof so far, plugged into the mains (my preferred choice) and the sensor reacts to a tiny fly so can't fault them but other than that, it doesn't do its job at all.

## Questions & Answers

**Q: How long is the extension cable that comes with this model?**
A: The extension cable is a good 10 metres.

**Q: How far from public land would this pest control have to be so it would not interfere with other people's dogs and horses**
A: The motion sensor works up to 50 square feet. The sound goes out about 70 square feet. However, the sound only comes out of the front of the device with a radius of about 150 degrees to the sides, so you can avoid aiming it at the public space.

**Q: How do you attach it to a wall ?**
A: It has two holes on the back which will hang over screws put in the wall.  It is quite secure but can easily be lifted on and off when necessary.

**Q: Can i put this on a table under a tree. i’m trying to stop pigeons shitting on the table. should i put it in a plastic bag. does wind affect it?!**
A: The  unit  is  weather proof,  so   I  would  not  use  a  plastic bag,   the  bag   would  also  weaken  the  sensor,  thus  defeating   the  desired  effect,  you  would  have  to  prevent it  from  been  blown  over  in  a  strong  wind,   maybe  stick  on  table  with   some  double  sided  sticky  tape  or  blue tac,  then  it  should  be  fine,  read  the  manual  for  your  desired   output  of  signal,  &  adjust  accordingly.

### ⭐⭐⭐⭐ Efective, but over priced
*by F***E on 11 September 2015*

My reason for buying this units is to keep other peoples cats out of my garden, which it does very effectively. I have nothing against cats per say, others that they are using my property as an official toilet . Access to the battery case and controls are difficult, as one has to wrestle the unit for some time and pain to close the back of the unit. This is a design fault and could have been better handled, by making it a screw lid rather than a badly designed clip-on. The settings to set up the unit to the sound level of specific animal one wishes to discourage are definitely made for the American or Canadian market. The It is not clear as one is moving the dial from one type of critter t the next that those animals in the lower range will not also be affected, rather than a specific mammal as per the dial, e.g. cat/dog and not also bats. Here in the UK bats are under protection, sa they are on our red book list. I also find it very expensive, when compared to other units. In defence it does have additional feathers such as dialling the specific creature. Other units one can also dial up different sound frequencies, but no clear description. It is very battery hungry, and they use C class batteries, which are not common use these days, which leads to anoretic high maintenance expense.
