This new MKlll version of the Nash Double-Top Extreme Bivvy differs from the MKll in its improved ventilation system and a host of subtle cosmetic changes. The unique twin-skin construction erects as one saving time and energy while the independent inner-mesh capsule provides total protection from mozzies and their like. The integral heavy duty groundsheet is complemented by a similarly robust door-mat and the extended porch canopy affords extra shelter and shade to the year-round, hard-core carp angler. The zip-off front panels can be clipped back onto the bivvy’s main body.

The Nash Double-Top Extreme Bivvy ( 2 man or 1 man version) comes to you in a dedicated carry-case along with a full set of Nash heavy duty T-pegs.


  • Waterproof outer
  • Integral inner mesh to achieve rapid set up and break down. Erects in half the time of other twin-skinned bivvies
  • Totally sealable, inner mesh capsule to optimise comfort and to eliminate mozzie invasions
  • Rear vents to enhance air-flow and comfort
  • New in-line spreader-bar system to optimise rigidity
  • Front waterproof, zip panels to expose mozzie windows and storm door
  • Manufactured to last in extreme conditions for years and years
Dimensions: 2.9m(W) x 1.4m(H) x 2.9m(D)
Weight: 16kg
  • Enhance your bivvy comfort with a dedicated third skin. This gives the angler increased insulation during the colder months as well as eliminating condensation drip. ( will fit MK2 Double top )

Frequently Asked Questions

What comes in the box?

Included with every FishSpy purchase is the FishSpy camera itself, a USB lead, one orange fin, one Foamy, one boom and the instruction and warranty information.

How long does the battery last?

The battery will last 4 hours, streaming live video to your portable device whilst recording the footage at the same time.

How much footage can I record?

FishSpy has a built in hard disk that will hold up to 7 hours of video. The video can be transferred to any other device by a USB lead. Videos stored on FishSpy itself can be managed/ deleted via the FishSpy app or control screen.

Do I need an Internet or phone signal for FishSpy to work?

No. FishSpy generates its own wifi signal which your portable device receives. There is no need to have a phone signal or access to the internet.

How deep can FishSpy be submerged?

It's guaranteed to perform at depths of up to 10m.

Will FishSpy transmit via Wi-Fi when fully submerged?

No - once submerged, FisySpy will lose its wifi connection to your device (wi-fi signals cannot be transmitted through water).

N.B. Your recording will continue whilst FishSpy is submerged, and will be ready for you to view when you re-connect FishSpy to your device once it's resurfaced.

How much does FishSpy weigh?

It weighs 90 grams so about the same weight as a large marker float.

What warranty is provided?

For complete peace of mind all FishSpy cameras are supplied with a 12 month warranty against manufacturing faults or defects. As you would expect this warranty excludes any accidental damage including but not limited to (water ingress through failing to lock the cap correctly, excessive force when tightening the locking ring, impact damage with a hard surface such as a rock or tree) or through natural wear and tear. Please follow the instructions and take care of your FishSpy and accessories because we cannot accept responsibility from incidental or consequential damages caused by the misuse of the FishSpy products or the accessories.

What a great bit of kit. Got this 2 man version for my annual trip to France to replace my trusty shakespeare cypry 2 man. Put it up in the back garden to check it out and it is huge inside. No instructions supplied but it is so easy to erect, a bit tricky to put down tho but had a look on the web ... No Comment
