It uses high-pitched ultrasonic output rather than liquid propellant, sprays, or chemicals. The unit has three ultrasonic channels operating at 20–25kHz and three sound wave modes, which allows you to vary the output rather than relying on one fixed frequency. That variation is intended to help with the common problem of a dog becoming used to a single sound. The device is rechargeable via a built-in 300mAh battery, so it does not need disposable batteries, and it is supplied in black with a hanging string for carrying.\u003c\/p\u003e\n\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black handheld ultrasonic dog bark deterrent with rechargeable 300mAh battery and three frequency modes\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US02\/6271\/2025-10-24\/original-image\/1619063422743.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe main construction points come from the source description: a compact handheld body, a built-in rechargeable battery, three ultrasonic channels, and a hanging string. There are no liquid propellant, spray, or chemical components, which keeps the device dry and free from consumable refills. The stated ultrasonic frequency range is 20–25kHz, and the unit is described as having three specific ultrasonic frequencies.\u003c\/p\u003e\n\u003ch3\u003eUltrasonic Output and Modes\u003c\/h3\u003e\n\u003cp\u003eThe device uses three specific ultrasonic frequencies within a 20–25kHz range. Three sound wave modes are provided so you can change the pattern of output. The source text notes that this is intended to solve the poor results sometimes reported with single-frequency units, where a dog may stop responding after repeated use. The unit is described as suitable for training and driving dogs, with an integrated training and driving function. No liquid propellant, spray, or chemical is involved.\u003c\/p\u003e\n\u003ch3\u003eBattery and Charging\u003c\/h3\u003e\n\u003cp\u003eThe built-in battery has a 300mAh capacity and is rechargeable in cycles. Because the battery is built in, there is no need to source or replace disposable batteries. The source text does not state charging time, run time per charge, or the type of charging connector, so those details are not confirmed here. Charging is simply described as cycle-rechargeable.\u003c\/p\u003e\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black handheld ultrasonic dog bark deterrent with rechargeable 300mAh battery and three frequency modes\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US02\/6271\/2025-10-24\/original-image\/1619063422757.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThis is a handheld unit intended to be carried on walks, during outdoor training, or kept close at hand for bark deterrence. The compact size and hanging string allow it to be carried in a pocket or held in the hand. It is aimed at pet owners who want a non-spray, non-chemical option for managing barking and unwanted behaviour.\u003c\/p\u003e\n\u003ch3\u003eOutdoor Walking and Training\u003c\/h3\u003e\n\u003cp\u003eWhen walking or training outdoors, the device can be aimed towards a dog without needing to shorten the distance beyond the stated effective range. The source text gives an effective range of up to 5 metres, and also lists 10 metres as an effective distance, so the exact working range may vary with conditions. The warning sound function is described as supporting dog training. The three modes let you adjust the output if a dog becomes less responsive to one setting.\u003c\/p\u003e\n\u003ch3\u003eEveryday Home and Garden Use\u003c\/h3\u003e\n\u003cp\u003eThe handheld format also suits use around the home, garden, or yard where a dog may bark at passers-by or other animals. Because no spray or chemical is used, there is no residue or propellant canister to deal with. The unit is described as harmless to dogs, other pets, and plants when used as intended. It is supplied in black and includes a hanging string for keeping it within reach.\u003c\/p\u003e\n\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black handheld ultrasonic dog bark deterrent with rechargeable 300mAh battery and three frequency modes\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US02\/6271\/2025-10-24\/original-image\/1619770592748.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe practical buying points are the lack of consumables, the rechargeable battery, and the multi-mode ultrasonic output. The device is designed for repeated use without refills or sprays, and the three modes address the frequency-immunity issue described in the source text. It is a compact handheld item rather than a fixed installation, so it can move with you between locations.\u003c\/p\u003e\n\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\n\u003cp\u003eThere are no liquid propellant, spray, or chemical parts, so there are no cartridges or refills to buy. The 300mAh battery is rechargeable in cycles, which supports repeated use. The source text does not provide a lifespan figure or a specific number of charge cycles, so no such claim is made here. Routine care is limited to keeping the unit dry and charging it as needed.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\n\u003cp\u003eThis product suits owners who want a handheld, rechargeable bark deterrent without sprays or chemicals. Its main differentiators in the source text are the three ultrasonic channels, the three sound wave modes, the 20–25kHz frequency range, the 300mAh rechargeable battery, and the compact size with hanging string. The stated range is 5 metres, with a 10 metre effective distance also listed. Exact dimensions, charge time, and run time are not provided in the source text.\u003c\/p\u003e","brand":"u9cmuw-dx","offers":[{"title":"Black","offer_id":58097463951740,"sku":"CJGY109273401AZ","price":25.88,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0951\/1685\/3628\/files\/1619770592748.webp?v=1793579858","url":"https:\/\/havenmere.co.uk\/products\/ultrasonic-handheld-dog-bark-deterrent-pet-trainer-with-3-frequency-modes-5m-range-rechargeable-300mah-battery-black-for-outdoor-walking-and-training","provider":"Havenmere.co.uk","version":"1.0","type":"link"}
