Carp Tech

How to Choose Carp Fishing Tech

Tech for the bank falls into five groups, which are power packs, bivvy fans, insect repellers and zappers, binoculars and underwater cameras. Start with power, since many fans, lights and phones now charge from the same USB pack.

Capacity is quoted in mAh, but watt hours give a fairer comparison between packs because they allow for voltage. A 20,000mAh pack here is rated at 74Wh, while the largest units pass 190Wh.

No pack passes on its full rated figure, as some energy is lost converting it to charge your device. Leave some headroom on top of what you work out you need.

USB-C with power delivery charges modern phones and tablets fastest, and the larger packs reach up to 80W from their USB-C ports. Several also have wireless charging pads, so a phone can sit on top without a cable.

Some packs add a DC socket for heated kit or other 12V gear. Check the plug size your kit needs before you buy.

The power packs listed weigh from about 357g for a small solar pack to 3kg for the biggest block. A light pack suits stalking and short overnighters, while the heavy units stay in the bivvy for a week.

Panels that run on sunlight can top up a pack in daylight, though they work slowly and need direct sun. On grey winter days, rely on a pack charged fully at home.

UK aviation rules allow power packs up to 100Wh in hand luggage, and packs over 100Wh up to 160Wh need the airline's approval. Packs over 160Wh cannot be carried as ordinary passenger baggage, which rules out the largest carp units for trips abroad.

A bivvy fan moves air through a closed shelter on hot, still nights, and most are USB rechargeable. Some combine a fan, a light and a small power bank in one unit, and a few come with a remote so you can switch them from the bedchair.

Evaporative coolers hold water and blow air across it for a cooler breeze. They weigh more once filled, so they suit longer static sessions.

Repellers release a repellent into the air around the swim, and they work best in sheltered spots, as wind carries it away. Some are DEET free and weigh little more than 100g, so they slip into a rucksack.

Zappers use a light to draw insects onto an electric grid instead. Several double as a soft bivvy light, which saves carrying both.

Binoculars help you spot fish showing, bubbling or rolling across a big pit before you choose a swim. The models here are 8x and 10x magnification with 32mm or 42mm lenses, weighing about 415g to 570g.

An 8x42 gives a 5.25mm exit pupil and a steadier, brighter view at dawn and dusk. A 10x42 shows more detail at range but magnifies hand shake too.

Underwater cameras let you see the bottom, your bait spread and how fish behave around it. The two here record 1080p and 2K video, and the smaller unit weighs just 64g.

Wifi models stream to a phone, so you can watch from the bank as the camera sits in the margins. Footage is clearest in shallow, clear water on a bright day.

What Carp Tech Costs

Across the whole range the dearest item costs around seventeen times the cheapest, though that spans small bug repellers to high end binoculars. Within power packs alone, the largest costs about five times the smallest, and every price is checked against reputable online tackle shops.

In power packs, extra money buys more watt hours, faster USB-C output and wireless charging. With binoculars it buys better glass and coatings that stay sharp in poor light.
