The question to ask is: “do I need a large ultrasonic cat repeller or will a smaller (and less expensive) model get the same results ?”.
All our ultrasonic cat deterrents work very well, but it’s a case of picking the right machine for the size of your garden and the severity of the problem.
If you have a small garden, our best selling, smaller cat deterrent STV610 (£26.99) with a 30ft range, will more than likely do the job. However, if you have a larger garden, or a large number of cats that use your garden as a toilet or dig up your flowerbeds, you might want to consider the benefits of the bigger, 150ft range Sentinel ultrasonic cat deterrent (£129.99). Or even our latest model, the ultra-powerful Sentinel 3 way that has a three way speaker system and a maximum range of 300ft (£169.99).
If you are considering splashing out on the Sentinel, one of our more expensive and powerful ultrasonic cat repellers, check the differences before you spend your hard earned cash.
The first and obvious difference is the effective range: 30ft for the STV610 cat deterrent compared with 150ft for the Sentinel. It’s not only the range in a straight line that is increased, but with the longer range, you also get a wider spread of ultrasonic sound from the 150ft model.
The huge benefit that comes with the bigger Sentinel cat repeller is the adjustable ultrasonic frequency. The main reason this ultrasonic repeller stands head and shoulders above other models is because the frequency is adjustable. The user can very easily fine-tune the ultrasound to get the optimum effect for the creature you are trying to repel. The frequency can be adjusted to also repel rats, mice, squirrels, foxes, birds etc.
As the Sentinel ultrasonic cat repeller is so powerful, it is mains powered and therefore always working, giving protection 24/7. It comes complete with a mains adaptor & 10mtr of cable.
We now have an even more powerful model with a range of 300ft. The Sentinel 3 way ultrasonic cat deterrent.
