Pros and cons

Pros

  • Waterproof coil claim supports searching in shallow water while keeping the control box dry.

Cons

What to know before buying

Listing details to confirm

The listing gives runtime as both 20+ hours in promotional text and 19.98 hours in product details. It also calls the coil 8 inches in some text but lists its size as 20 centimeters, and gives the stem range as 41.7" to 51." while listing an extended length of 51 inches. Treat depth, runtime, dimensions, and performance as listing claims and confirm the selected product details if these figures are decisive.

Who is it for?

A good fit for

  • Beginners or families looking for a detector with four selectable modes and adjustable length.
  • Shoreline and shallow-water hobby searches where the coil may enter water but the control box remains dry.
  • Users who prefer a rechargeable detector with an LCD and headphone connection.

Less suited to

  • Searching with the control box submerged or exposed to water.
  • Buyers who need independently established detection depth or a clearly consistent runtime and size specification.

The supplied evidence includes aggregate customer ratings but no review-summary or individual-comment evidence. The ratings lean positive overall, while the smaller lower-star share shows that experiences are not uniformly favorable. They do not establish what customers liked or disliked, nor do they verify the claimed modes, depth, battery life, or waterproof performance.

Frequently asked questions

Can the whole detector be used underwater?

No. The listing says the search coil is IP68 waterproof but explicitly states the control box is not waterproof. It describes shoreline and shallow-water use, not submersion of the whole unit.

What detection modes does the OT-MD17 list?

The listing names All-Metal, Notch, Memory, and Pinpoint modes. It describes Notch as filtering selected unwanted targets and Pinpoint as narrowing a target's location.

How long does the battery last?

Product details list 19.98 hours, while promotional text claims 20+ hours. These are listing claims, and the discrepancy is worth checking if runtime is important.

How deep can it detect targets?

The listing claims detection up to 8 inches deep. Actual results may depend on the target and conditions, and the stated depth is not independently verified here.
