Boomerang Tool Company Boomerang XD Retractable Electronics Tether, 36" Kevlar Cord, Retraction Lock, Green Polycarbonate Case, for Rangefinder and GPS Units 0TRG-2413-EL

This is an excellent tool and works exactly as needed. My husband uses it to keep his hand tools within reach while he works, and it has made a big difference. No more searching for the tool he just set down. It stays securely attached and ready to use. The tether is strong and smooth, allowing him to use the tool freely and then let it retract right back to his hip. Simple, sturdy, and very convenient.

Awesome retractable! I have used it for holding my insta360 scuba diving, as well as used it for securing my phone paramotoring. The retractable is long enough to get good video. The clip on it is solid and sturdy. I will be buying more in the long run

I would rate higher but the lock is hard to put on and off and it's quite loud. It is very secure though. The cord retracts very well and that part is quiet if you let it down slowly.

Product works great. A little noisier than I’d like for bow hunting but it’ll do the job.

If you kayak you know that anything that's not attached will eventually be lost. These tethers are a great way to keep your pliers, boga, clippers, radio, phone, etc. The only drawback is the size of the reel. It's a little larger than I would prefer. That said, it's sturdy and everything is secure and easy to clip to my Hobie Outback. I fish in salt water and periodically spray a little WD40 inside and outside on these to keep salt water from affecting small parts. Haven't had any problems with them. Good product.

It's a little bigger than I expected but, it attaches to my rangefinder and, supports its weight perfectly.

Far too noisy to be be useful for hunting.

I like locking feature. Has a strong rewind it will pull my rangefinder back up.

Useful and resistant
